Mr Federico Pucci is the very first precursor of machine translation as we know it today! Here is his
Two years after the publication of my first “scoop” regarding Federico Pucci and his mechanical
translator, this post is a synthesis of the research conducted in collaboration with Oriana de
Majo, Federico Pucci’s granddaughter. It gives a summary of 19 previous articles (9 published on
Adscriptor, 10 on Translation 2.0, mainly in French and in Italian), and it attempts to deliver a definitive
answer to the question: did Mr Pucci’s “translating machine” ever exist?
The mechanical translator
In December 1929 (ninety years ago) Federico Pucci presented, in Salerno, for the first time, his
study on the “mechanical translator”, subsequently disclosed to the Italian press in January 1930. In
this same year he displayed the “mechanical translator”, that put his ideas into practice, in the
literature section of the Bolzano National Exhibition for six months. For his study, he was awarded a
This information is given by Federico Pucci himself in his first letter to the CNR (National Research
Council), of 10 July 1949. But he also mentions this fact much earlier, in the preface to his book
published in Salerno in 1931 (or Year IX of the fascist era!), in the first section of what might be
considered the first book ever published on a “machine translating” device, called: “Il traduttore
meccanico ed il metodo per corrispondersi fra europei conoscendo ciascuno solo la propria Lingua:
Parte I.” (The mechanical translator and the method to communicate among Europeans, each native
speaker knowing only his own language: Part I). The book had this cover:
Naturally the term “part one” meant that at least another volume was envisaged. The author adds on
the cover: “Preparatory work for translating from one’s own language to a foreign language. Time
required for learning how to translate: one minute (French language)”. With 68 pages of descriptions, it
is not only his first work, but also the most comprehensive.
In his preface, drafted in Salerno on 10 December 1930, the author states: “This work sets out to
demonstrate that it would be possible to communicate among foreigners, each native speaker knowing
only his own language”.
Then, he gives an example of an Italian text translated into French, and of a French text translated into
Italian according to his method. These are probably the first examples ever of a “machine
translation” (long before the term “machine translation” was coined).
Pucci illustrated his method for “automatically” translating the text from Italian into French (Federico
Pucci dixit) and the other way round. The first consideration is that it would not be easy to try to
translate these texts even by current translation standards. So, one can only imagine the difficulties
involved in translating it “automatically” 90 years ago...
I am still examining this material in order to fully understand how he could achieve such a remarkable
As I have already stressed, Pucci’s vision and approach to translation differed radically from any other
previous (and future, we may add) endeavour. Indeed, already in 1929, he dreamed of creating an
easy (Time needed for learning how to translate: one minute…), handy and economical machine. In
1950 he was actually selling his book at just 150 liras, and for 600 liras (almost 1 USD) he would add
It was obviously a utopia: the portable, inexpensive machine he was dreaming of (less than one
USD...) remained at a blueprint stage, even though his idea was nearly a hundred years in advance!
His invention pivoted around the following main ideas:
• firstly, to divide the text into the smallest units of meaning (morphemes),
• then to transpose these units into the foreign language,
• finally, the receiver puts the words (generated by the machine) back into the order of the
target language, of which he is a native speaker.
He was actually anticipating two concepts that are widely recognised today: that of language
simplification, and that of good enough translations.
A method that is both logical and practical, making use of ideograms (basic & derived) invented for the
purpose by Federico Pucci himself in the 1920s. His only aim was to enable people (including less
educated members of society / anche le persone di limitata cultura) to see in their own language the
words spoken by a foreigner that they would not have understood otherwise.
A method that had been in the making for quite a long time, certainly not last-minute improvisation. Its
inventor was 33 years old when he first presented it to the general public. This means he would
already have been cogitating for a long time (he was 27 when he published his first known work in
1923, entitled Manuale di letteratura Inglese : Parte I (I principali scrittori) (English literature manual:
Part I (the main writers) (Salerno, Tip. Fratelli Jovane), not to mention all that he wrote for the next 30
years (I have come across 10 of his books) to describe and get people interested in his evolving
He devoted his entire life to this invention but did not received due recognition, disappearing into
oblivion for decades!
Let me now translate the two charts of international keys (basic & derived) and the rules for the
practical application of the charts proposed by Pucci. This is the core of the invention, what the
translating machine was intended to transpose “mechanically” to permit the “automatic”
translation from one language to another.
The first step in Federico Pucci’s method was to draw up a system of international “keys” valid for the
Romance languages. Below are the two charts proposed by him:
Moving on from theory to practice and from synthesis to analysis, here is a chart of
the fundamental keys valid for the Romance languages. With one or two additions, we
will see that the same keys hold good for those Germanic and Slavic languages too.

Conditional “K” was chosen as a symbol
because the term conditional

Mr Pucci later developed and added a second chart of basic keys by inflecting personal pronouns,
articles, possessives, demonstratives, etc., with the aim of “enabling less educated people (this was
back in the 1930s) to easily come up with the equivalents in Italian.”
These charts were followed by rules for their application, and with the explanation for their operation:
1. The words indicated in the second column of box A must be replaced by the corresponding
ideogram, with the exception of m and f, which must be joined to the adjective with a dash,
indicating gender, e.g. buon libro, write: “buon -m libro” [concept: good (masculine in Italian)
2. The ideograms in box B express the variation to the concept of infinitive produced by the
inflection of the verb. For example, for the Italian word porterebbe, knowing that this is the
conditional of the verb portare, one would write portare
3. One should attempt to express propositions as direct constructions and include abbreviated or
implied words), e.g. to convey the expression I’ll leave tomorrow, you write: I shall leave
tomorrow, i.e. I leave (ideogram of future) tomorrow.
4. Diminutives, nicknames, etc. should be replaced, having the modified entry preceded by an
adjective that provided the intended meaning of the altered word: e.g. giardinetto = piccolo
giardino (small garden).
5. Expressions that are rare in the language being translated should be replaced by simpler
terms expressing an equivalent meaning.
If the foreigner replaces the words received with terms found in the dictionary, he shall automatically
obtain the version in his own language, bearing in mind that for names that vary in terms of gender,
the dictionary will indicate the variation, and this change will have a knock-on effect on connected
Thus, if as an Italian, I wish to communicate with a French “una buona scelta”, I will write “1 buono-f
scelta”. In the dictionary the French will find: scelta, f, and understand that the Italian has given to the
adjective “buono” the character “f”, because “scelta” is a feminine word. However, as the
corresponding French term, “choix”, has a masculine gender, he understands that the “f” for “buono”
takes the value “m” in French, thus, it becomes “1 bon -m choix”, that is “un bon choix”.
Since the above-mentioned system clearly expresses the interdependence of words, the order in
which words may be placed, on account of the way sentences are constructed in different languages,
has no bearing on the interpretation of the thought. Anyone who has studied Latin will know this very
Let us take an example from English:
The future tense in English, translated, say, to Italian: I shall give him a good pen.
Knowing that I shall give is the future of the verb give, we have:
I give III3 14 good -n pen.
In Italian this gives us: I dare III3 14 buono -f penna.
[In French: I donner III3 14 bon -m stylo.]
And we can reconstruct, from the chart rules, the following: Io darò a lui una buona
And in more correct Italian:
Io gli darò una buona penna...
If we apply these rules to the Dante passage (from La Vita Nuova),
phrases are reduced to morphemes, the smallest units of meaning (noun, infinitive of the verb,
adjective, adverb, etc.) to be translated using the portable dictionary incorporated in the machine, thus
producing a message made up of ideograms (international keys having the same meaning in different
languages) and words translated into the language of the native speaker, who simply has to put the
words in the right order.
Look at the result here...
We are talking about the 1930s... I have translated the same passage from French into Italian using
Google’s neuronal machine translator, 90 years later. Apart from the missing phrase in Federico
Pucci’s text, I would be hard pressed to say which version is the best one!
And Pucci concludes (I am paraphrasing here): “This translation is quite correct, [and undoubtedly
better] than what a secondary school pupil could manage after having studied French for a few years.
Now, we are not looking for a perfect translation, only a way to understand, and there is no doubt that
a Frenchman would be able to understand the sense of the produced text.”
This is the concept of the “good enough” translation, already supported in 1931, when the author was
just 35 years old...
Reporting on a conference held by Mr Pucci in Salerno on 21 January 1930, published on 6 February
1930 in the Salerno edition of the newspaper “Il Mattino”, the journalist wrote: “Mr Pucci first
demonstrated that all the attempts by foreign scientists made over the last three centuries had
achieved no practical results, and then in an extremely practical way he presented his own method,
getting persons who had not studied English and German to translate some phrases in those
As the journalist reports, during the presentation of the book, Pucci had members of the audience
translate some phrases from Italian into English and German and they did not know either of the two
foreign languages. Should we infer that they availed themselves of a machine invented by Pucci?
A reply may be given by through careful analysis of the words chosen by the journalist: “Mr Pucci first
demonstrated… in an extremely practical way his own method, getting persons…”. As in the subtitle to
Pucci’s book, the journalist does not write about a “machine”, rather merely about a “method”.
Which is obviously not the same thing. [Top]
The Bolzano national exhibition (1930) – The precursor to “translating machines”
Now, let us go back to the silver medal obtained in Bolzano. It is an extremely relevant detail, as it
means that a prototype of the “mechanical translator” had already been on display in 1930. But was it
really a “machine”, a “prototype” developed by its inventor, or something else?
Well, there was no machine. Thanks to the magic of the Internet, I have found an edition of the
catalogue of the first National Exhibition of Arts and Crafts of Bolzano, with a collection of official
photographs of the fair, referring to the period June – November 1930.
The December 1929/January 1930 presentation had been organised by Dopolavoro Ferroviario
(Railway Workers’ Recreational Association) of Salerno. This might explain Pucci’s participation in
what was his first exhibition, the aim of which were:
1) to confer awards on those participants whose products are the creative expression
of after-work activity devoted to the creation of fine works, in the sphere of the arts
Some works were models, such as this radiotelegraph transmitting station. Thus, even without
mentioning a “machine”, if there had been a model of the “mechanical translator”, it would have
obviously taken its place in the catalogue. Unfortunately, there is no article referring to it, and no
photo of either a model or a machine!
Anyway, in the light of the above-mentioned time references and historical records, it is safe to say
that Federico Pucci's machine translation concept was almost a hundred years ahead of his time.
He was also a few years ahead of the patents filed in 1933 by French engineer Georges Artsruni, of
Armenian origin, and Soviet engineer Petr Petrov-Smirnov Troyanskij, the universally recognised
pioneers of machine translation for their mechanical brain and automated dictionary respectively.
Hence, we have the documentary evidence of Artsrouni and Troyanskij’s translating machines, but no
certainty about Pucci’s “mechanical translator”. So far, all my researches to find a concrete, physical
trace of his machine have failed.
I have reached the conclusion that the machine never existed, despite the considerable amount of
energy and efforts devoted by its inventor to build one, although Pucci made a new model for each
edition of his “machine-book”.
Federico Pucci had a very clear vision of what his “translating machines” should be like. He himself
talks about his protean idea:
Notes on machines and how they work
Translating machines can be of different types: simple, mechanical, electrical,
phonoelectric, photoelectric and remote-electric. These then give rise to numerous
mixed types, including the Portable Electromechanical Interpreter, awarded a prize at
the Liège Inventions' Competition.
Let me explain the general concept underlying these machines. The pages of the
portable dictionary, which in the model presented consist of two columns glued onto
cardboard, are pushed forward by a human hand. If one had to express the phrase
“egli va”, to an Englishman, the phrase begins with the letter e, so the letter E is pulled
out by hand, bringing up the page containing the words that begin with E. The second
letter of the first word leads us to immediately find egli – he. And the same for
“andare”, which gives us to go. Since we are using the present indicative, we look at
the morphological corrector and find that for the present indicative 3rd person singular
the verb form is oes; thus, he goes.
In the electrical type, elements are moved by electricity rather than by hand. In the
phonoelectric type, the portable dictionary is arranged in three columns, the first two
printed on the canister, the third consists of a steel disc, like that of a gramophone.
This records the voice of the foreign language speaker with the pronunciation of the
translations in the foreign language. Next to each Italian word there is a number. By
pressing a button, a hook electrified via a magnetic field goes to the recorded
pronunciation and reads the word in the foreign language, after an electrical
movement has undertaken the graphic and phonetic correction. In the example given
above, the o is replaced with oes. The remote-electric system entails the use of two
electric translators, one working as a transmitter, located for instance in Rome, the
other as a receiver, for instance in London. By connecting the two devices via a
teleprinter the same movements undertaken by the transmitter are recorded on the
London-based device, resulting in both a written and spoken “remote” translation. In
subsequent types the syntax-correcting part B is incorporated in the portable
dictionary. I have used this instrument to make the dictionary simpler for my
experiments. I have chosen English as an initial application of the system as there are
few morphological variations in this language. For sound experiments Spanish will be
the preferred language, and the first phonoelectric trials will take place between Rome
(perhaps the Accademia Universale Inventori ed Autori) and the telephone exchanges
of Spanish-language organisations allied to the Pro Pace(*) (…) With those types in
which the portable dictionary is complete, the first letter is brought out, taking with it
the folder that includes all the words that begin with that letter. Then there is the
second letter that is brought out using the same system, bringing to the fore the third
letter, and so on.
By replacing the electrical or manual movement with a keyboard, it may be possible to
type in the word, in order to bring out the foreign word. This is the system I presented
in Paris in September 1949, reported by the official French radio at 8 p.m. on 2
September 1949, and by the English newspaper News Chronicle on 26 August 1949
(*) Pro Pace: International Association of which Pucci was Chairman
Yet although he spent all of his life trying, writing continuously for thirty years describing his invention
(as far as I know in 10 books, from 1931 to 1960), after nearly a century his numerous attempts at
“translating” his vision and concept into a “physical device” did not result in any great success.
The only two “awards” we have (Paris 1935 and Liège 1950, since it appears that the silver medals of
Bolzano and Cuneo have been stolen) tell us as much, just as the numerous other clues tell us about
his failed attempts to build his machine.
Now let us examine more closely: 1) the awards; 2) the clues. [Top]
1) The awards
a) Paris, May 1935
I first thought that this award, issued in May 1935 by the Paris Trade Fair Committee, referred to the
Lépine competition, usually held as part of the Paris trade fair. However, the 33rd Lépine competition
was held from 30 August to 7 October 1935, at the Porte de Versailles exhibition centre, more than
three months after the award was issued.
The answer lies in the monthly journal of the International industrial property protection office, entitled
“La Propriété Industrielle” (51st year, issue no. 4, 30 April 1935):
“…alongside the Paris Trade Fair, to be held in this city from 18 May to 3 June 1935
at the Versailles Exhibition Centre park, an invention competition will be held, open
from 10 May to 3 June (decree dated 22 March)”…
Certificates of guarantee will be issued [for the Paris event] by the Industrial property
director…, under the conditions set forth in the decrees of 17 July and 30 December
It is specified that the Paris Trade Fair Competition only accepted “truly new inventions never before
presented in other competitions”.
The previous year, “even though most of the projects submitted were of real interest, after a very
careful examination the panel conferred awards to only 170 of the 643 inventors taking part in the
Competition, who had submitted a total of 1,055 new inventions. The rigorousness of the panel
implies that only meritorious inventions were given an award. This shows the high level of the
competition and the interest it garners for both researchers and industry.” (Source)
So, this award attests to a silver medal rewarding a “truly praiseworthy invention”: “a method to
translate languages without knowing them”!
The same term as the one used by the journalist in 1930. The words are once again of prime
Pucci himself confirms this at least on two occasions. First in one of his books, in which he writes “This
is the system I presented in Paris in September 1949”, then in his first letter to the CNR: “this study
[was] awarded a silver medal at the international invention exhibition held as part of the Paris trade fair
A “method”, a “system”, a “study”, but not a “machine”.
- - -
b) Liège, 1950
This International trade fair took place in Liège from 29 April to 14 May 1950 with the theme “At the
forefront of technology”, in particular in the areas of “mining, metallurgy, mechanical engineering and
This is probably why, in his book, Pucci describes the invention presented on that occasion as a
“Portable Electromechanical Interpreter”, while the award refers to a silver medal that Pucci won for
“Written and spoken translation of languages without knowing them”.
An expression that appears to rule out any idea of a “machine”, notwithstanding the name chosen
by its inventor on this occasion, probably in order to make his invention relevant for the themes
concerning the trade fair. [Top]
2) The clues
The main clues are given to us by Mr Pucci himself in his two letters to the CNR, written on 10 July
1949 and 17 October 1950 respectively, and in the CNR’s reply, dated 20 July 1949, to the first letter,
referring to: “…the Italian electro-mechanical translator that will participate in the invention competition
that will be held from 16 to 29 September in Paris”.
“…I should say that in 1936 I was also allowed to participate in the Leipzig Exhibition. However, the
International Inventions Exhibition, held in the same city, did not accept my submission, even though it
acknowledged my studies and their inventive nature, as in view of the originality of the invention, the
only one to be contained in books, German law did not allow the patenting of the invention, unlike
French law. I had indeed been granted a provisional patent in France. In view of the German interest
in finding out about the innovation, the Leipzig Trade Fair organisation worked for my admission in
another section, granting me a special dispensation.”
So, no machine existed.
- - -
Then the war came, and I attempted to steer my studies towards a military use. I managed to create
mechanical translating devices “C” and “D”, a mechanical solution, attempting to create a new
mechanical-based language, with device C working as a transmitter, and D as a receiver device. They
were to be submitted to the 1940 Engineering Exhibition, but the War Ministry opposed its
participation. I was called to Rome to explain the invention. It was approved, and I was authorised to
build and try out the device, at the State’s expense, since I had informed them I could not afford to
build it on my own. Obviously I was obliged to keep everything secret. However, as I was not a
mechanic, I thought that I would need the assistance of other persons, who might not be able to keep
the secret. I did not want to run this risk, so I turned down the assignment, and left the invention in the
hands of the War Ministry, so that it might do whatever it wanted with the idea.
Let me to stress Federico Pucci’s words: “I was authorised to build and try out the device, at the
State’s expense”… “However, as I was not a mechanic …, I did not want to run this risk, so I turned
down the assignment, and left the invention in the hands of the War Ministry, so that it might do
whatever it wanted with the idea.”
So, it can be argued that no machine was ever built, either by Mr Pucci or at the behest of the War
- - -
In the first two paragraphs of his second letter to the CNR, Pucci states:
- First paragraph:
I respectfully note that… following some blueprints that I presented at the Paris Exhibition of
Inventions (September 1949)…
Presentation of “blueprints” and not of a “machine”.
This was also mentioned in the first letter:
The three-stage dynamic-mechanical translating device has been allowed to the
international inventions' competition, that was part of the Paris Trade Fair, opening on
16 September (…)
It should be noted that the Paris Inventions Exhibition also accepted inventions in
the form of blueprints, in such cases merely checking the correctness of the
The Industrial property office in Paris is working accordingly to issue a certificate of
guarantee in favour of the undersigned.
Here, the mention of a “certificate of guarantee” is relevant, as it corroborates what we have already
seen in the monthly journal of the international industrial property protection office, entitled “La
Propriété Industrielle” (51st year, issue no. 4, 30 April 1935):
Certificates of guarantee will be issued [in the case of Paris] by the Industrial property
director…, as per the conditions set forth in the decrees of 17 July and 30 December
Going into further detail, the decree of 17 July 1908 was promulgated in order to implement the “Law
of 13 April 1908 concerning the temporary protection of industrial property in international exhibitions
held overseas or officially recognised exhibitions, such as exhibitions organised in France or overseas
territories with the administration’s authorisation or its patronage”. Art. 1 of this decree states:
Temporary protection is granted to patentable inventions and industrial blueprints,
trademarks or brand names for products that are correctly admitted to such
While art. 2 (in the version updated through 5 September 2018) states:
Exhibitors wishing to obtain temporary protection, shall seek the issue of a certificate
of guarantee to ensure that the item for which protection is requested, is
actually on display.
This certificate shall be requested during the exhibition and by no later than the three-
month period from the official opening of the event. The application shall contain an
accurate description of the item to be protected and, if applicable, the blueprints
relating to the item.
So according to Federico Pucci himself, the industrial property protection office of Paris issued to him
a certificate of guarantee not for the “translating machine”, which had not in any case been
built, but for its “blueprints”.
- Second paragraph:
The Inventions Institute appears to hold the view that although the Invention is of scientific relevance
(having retraced case no. 11095, in which the Institute approved the undersigned’s invention,
however, since it consisted of a book and not a machine, decided that it could not be patented, 12

mechanical translator” may be submitted to the National Institute for the Examination of Inventions…

judgement which, if favourable, will enable us to provide suitable assistance for the development of the
Thus, we can see that what Pucci presented is a blueprint for an invention that was never fully
And so, the final answer is...
Summing up, in view of the many elements and clues that I was able to gather, I dare say that the
answer to the question: «Did Federico Pucci’s “translating machine” ever exist?» is NO!
Sadly, Pucci was left alone with his exceptional foresight and could not manage to pool together
enough financial and technical resources to build a prototype. And so, he was not able to patent an
invention that never went beyond the conceptual phase, with its blueprints, models and descriptions.
Yet Mr Pucci continued to take part to numerous exhibitions and to write several books on the subject,
using all the means at his disposal, in order to promote his “translating machines” and their novelty:
➽ in 20 years, from 1930 to 1950, he took part to seven national and international exhibitions
and invention competitions (the terminology used by Pucci in his letters), without mentioning the 1940
Engineering Exhibition (I imagine in Rome, participation in which had been blocked by the War
Ministry), receiving a total of four silver medals:
1. Bolzano National Trade Fair (1930), silver medal
2. Cuneo Trade Fair (1930), silver medal
3. International Inventions Exhibition, Levante Trade Fair, Bari (1934)
4. International Inventions Competition, Paris Trade Fair (1935), silver medal
5. International Inventions Exhibition, Leipzig (1936)
6. Inventions Exhibition, Paris Trade Fair (1949)
7. Liège Inventions Competition (1950), silver medal
➽ in 30 years, from 1931 to 1960, he wrote ten books about his “translating machines”:

The announcement of 26 August 1949
All of the above in order to achieve a single tangible result - after such a great deal of energy and
resources over such a long period of time -, a simple announcement published on Friday 26 August
1949 (seventy years ago this year), both in Great Britain and in the United States.
In Great Britain the News Chronicle published the following in one of its columns:
You type in English, it prints Greek
British tourists should be able to circle the globe without having to learn languages if
inventor Frederico (sic!) Pucci, of Salerno, completes his “electric translator”.
He says that it will be ready in about a fortnight.
On Pucci’s machine one merely types words in, say, English, and the machine prints
them in Italian, Greek or any other language.
So, the machine was not yet ready, and Federico Pucci had refused to supply further details...
In the United States, the United Press issued an agency release on 25 August 1949, which was
picked up the day after by the New York Times:
and by several American newspapers over the following days (from 26 to 29 August). Thanks to
Google I found a dozen or so such articles on the Internet. There will undoubtedly be others (click on
the image to see the list):
The titles are different, but they all repeat the same text, along these lines:

And after that, complete silence. And total oblivion for almost half a century! Until John
Hutchins, a specialist and historian of machine translation, reported the few lines from the New York
Times mentioned above...
Before adding: “and nothing more is known about Pucci...” and:
It is not known how many others at this time had similar ideas about translating
machines. The new electronic computers had caught the imagination of many people.
Reports on the 'electronic brains' – the term regularly used by journalists – appeared
almost daily in national newspapers throughout the world. Translation was then, and
often still is, regarded by those unfamiliar with its difficulties as essentially a question
of finding equivalent words in another language. To use a computer in such a task
What we can be sure of, however, is that this consideration does not concern Mr Pucci. By 1949 he
had already been attempting to theorise the “machine translator” for some 20 years, well before the
era of the computer. And he had been the only one to do so back then.
And then, a return to total oblivion for another two decades! Until the undersigned, while preparing
an infographic on the history of machine translation, read the article reported by John Hutchins. This
discovery was so mind-blowing that I forgot all about the infographic and concentrated my research on
the remarkable story of Federico Pucci…
His idea of what machine translation should be like, was completely different from that of all other
researchers in the field. He had realised right from the start that the brute force of a machine would
never be able to convey properly the extreme fluidity of a language. French, Russians and Americans
realised this at their expense, having kissed goodbye to millions and millions of francs, dollars and
rubles since World War Two, without having anything tangible to show for it. Until Google came...
I imagine that the registered letter sent to President Truman (probably in late April/early May 1949)
didn't have the sole purpose of receiving financial support for the construction of electric translator
devices, but Pucci also had the intention of date-stamping his blueprints. In 1953 he sent a second
registered letter, this time to Clare Boothe Luce, then ambassador of the United States in Rome. It
His approach is very clear, and can be seen in particular in his first letter to the CNR, in which he
claims paternity for the invention of the electronic brain announced by the Americans [citing the works
of Harry Huskey, who intended to use his SWAC (Standards' Western Automatic Computer) for
machine translating, information also reported by Mr Hutchins], and also stresses its extremely high
1) the huge sums of money made available by the US Government for the
construction of the electronic brain, even though it cannot be marketed, is unsuitable
for the intended purpose and can be used only to translate to and from the national
2) tens of thousands of lire would be needed to build Italian electro-mechanical
translating devices, not billions of dollars;
3) Italian electro-mechanical translating devices would have a limited cost, could be
mass-produced for both domestic and overseas markets, and could bring in far more
for the State than their original cost. The undersigned, certainly believes that with the
help of Italian electro-mechanical expertise, it will be possible, in the near future, to
type a text in Italy and obtain the translation overseas, both written and spoken.
It is a view that foreboded the global democratisation of machine translation as we know it today, a
phenomenon that will grow more and more in the future.
I am quite frankly amazed by, and fail to accept, the deafening silence regarding the existence of
Federico Pucci, since I started talking about him on the Internet and publishing my discoveries about
him. Except for one student doing a master’s in translation, so far, no researcher, academic or any of
the main experts of machine translation has contacted me or looked more closely into this new
material, which evidently clashes with the accepted history of MT.
And when I have tried to talk about him to some experts, I have at best been greeted by a
condescending smile, at worst I have been completely ignored! Perfectly in keeping with the haughty
indifference that has always been shown to Mr Pucci’s work and human adventure.
Keeping things in due proportion, his story is not dissimilar to that of Charles Goodyear, who spent his
whole life attempting to get his invention acknowledged, in vain, dying in the most abject misery. [Top]
A man of ingenuity and of culture
His daughter had the following words inscribed on his gravestone:
Cav. Federico Pucci, 23/03/1896 - 6/03/1973
A man of ingenuity and of culture
Federico Pucci was also a renowned linguist. There are at least three certificates issued by the
Prefecture of Salerno attesting to his linguistic expertise.
On 19 August 1940, a letter regarding the Provincial censorship commission – Interpreters,
addressed to the Interior Ministry by the Prefect of Salerno, mentions Federico Pucci:
There is also an employee of the State Railways company who not only knows
[German, French, English and Spanish], but is also an expert in the following
languages: Czech, Portuguese, Dutch, Swedish and Slavic languages.
In another letter, dated 30 October 1942, concerning the War Censorship Service, again addressed to
the Interior Ministry by the Prefect of Salerno, the situation is described as follows:
This Provincial Commission has been receiving for some time copious amounts of
correspondence, for its censoring, written in French, Dutch, German, Spanish,
Portuguese, Catalan, Romanian, Esperanto, Swedish, Danish, Flemish, Norwegian,
Russian, Bulgarian, Polish, Slovenian, Croatian, Bohemian, Czech, etc. from other
Commissions, especially those in: Naples, Rome, Catanzaro, Brindisi, Bari, Ancona,
Benevento, Campobasso, Avellino, Caltanissetta, Florence, Catania, Syracuse,
Reggio Calabria, Messina, Palermo, Ragusa, etc.
The excessive amount of translation work needed has been assigned to acting censor
Cav. Pucci Federico, an employee of the State Railways company, who is a skilled
polyglot, and who almost every day is required to work beyond normal working hours
and to make an extra effort to ensure the smooth running of the service.
I propose that Mr Pucci, who has performed exceptionally in both quantitative and
qualitative terms, be given a monthly salary of L. 700 in view of his status as sole
Finally, Prefect G. Cenami, in a document dated 15 September 1948, written in his capacity as
“Chairman of the Provincial War Censorship Commission”, notes that Mr Pucci was “a renowned and
expert polyglot… in around thirty languages!!
… During the war, in particular from July 1940 to July 1943, Rag. Pucci carried out
(…) the duties of translator-censor of foreign correspondence handled by the
Provincial war censorship commission of Salerno.
Mr Pucci, a renowned and expert linguist, was assigned the task of translating and
censoring not only civilian correspondence written in around thirty foreign
languages arriving in Salerno, but also correspondence from numerous other
Provincial Commissions endowed with translators, as per ministerial orders. Mr Pucci
carried out these duties commendably and with great discernment.
It should be noted that the second letter mentions “Cav. Pucci Federico”, including the honorary title of
Knight that we also see on his gravestone. His granddaughter and I wondered about the origins of the
honour conferred, and above all about the reasons for it. We first thought about it being for work-
related merits. This honour however, was created in 1951, while the Quaestor of Salerno’s reference
is prior to that date! So, it could only refer to Knighthood of the Kingdom of Italy and not of the
Republic. It was more likely to have been of the order of the Crown of Italy.
After extensive research, Federico Pucci’s granddaughter found his grandfather’s nomination for a
Knighthood, dated 27 October 1936 (year XIV of the fascist era), signed by Victor Emmanuel III, King
of Italy and Emperor of Ethiopia!
“Having regard to special merits;
Having consulted the Board of the Orders of St Maurizio and St Lazzaro of the Crown of Italy;
At the proposal of the Head of Government, Prime Minister and State Secretary (Mussolini) and the
Minister for Communications (Antonio Stefano Benni)
This is to nominate
as Knights of the Order of the Crown of Italy, with the power to bear the insignia established for the
said grade, the following three hundred and seventy-one persons:
Pucci Rag. Federico – Head of operations 2nd
cl. - Naples 263
The Chancellor of the Order is hereby tasked with enacting this Decree, which will be registered with
the Chancellery of the Order.
Delivered at San Rossore, 27 October 1936 - XIV
I believe the key clue here is “At the proposal... of the Minister for Communications” for services
rendered by Federico Pucci, before acting as a translator and censor during the war. And this was
probably an acknowledgement of the award obtained in Paris in the previous year, for his “method for
translating languages without knowing them”!
So what should we conclude, on the eve of the 90th
anniversary of Pucci’s concept of machine
translation? I believe that the rich and intense journey already travelled is much shorter than the one
that is still ahead in order to ensure universal recognition of the role played by Federico Pucci as one
of the first pioneers of machine translation, and for a University, or one of the leading actors of
machine translation (Google maybe?), to take up his work and his ideas and finally build a working
prototype, in line with his protean vision of “translating machines”…
I hope I managed to stir your curiosity on Federico Pucci's legacy in the field of “mechanical
translation”, the unknown ancestor of what is currently known as “machine translation”. [Top]
P.S. The history of machine translation in the 20th century now needs to be rewritten from the
1929 (December): Federico Pucci presents his study on the “mechanical translator” for the first time
1930: Federico Pucci’s participation in the first National After-Work Arts and Crafts Exhibition of
Bolzano – literary section, with his concept of “mechanical translator”, awarded a silver medal.
1931: Federico Pucci publishes in Salerno the first part of what we might consider to be the first book
ever published anywhere on a “mechanical translating device”, called: "“The mechanical translator
and the method for Europeans to correspond, knowing only their own language: Part I: Translating
from foreign language).”"
1932: likely construction of a prototype “translating machine” by Georges Artsrouni, later destroyed.
No document has been kept about it, except for a photograph that makes a description impossible.
1932: Warren Weaver becomes director of the Rockefeller Foundation.
1933: filing of patent and presentation to Soviet authorities of Petr Petrovič Smirnov-Trojanskij’s
machine, probably at the design and description stage. (Source)
1933-1935: construction of Georges Artsrouni’s “mechanical brain”:
1935: presentation of Federico Pucci’s “mechanical translator” at the Inventors Competition, part of
the Trade Fair of Paris, receiving a silver medal for a “a method for translating languages without
knowing them”! (Source)
1937: Georges Artsrouni presents some machines at the National Exhibition of Paris, the principle of
which received a Grand Prix award for mechanical data processing, according to the inventor himself.
1939-1945 : World War Two
➽ Federico Pucci’s publishing activity is interrupted between 1931 and 1949, a time corresponding to
the pre-war, war and post-war periods, during which little is known about Federico Pucci, apart from
his participation in some Exhibitions and his work as a censor, about which he writes:
