Stephen Hawking was a renowned theoretical physicist and cosmologist born in Oxford, England in 1942. He held the Lucasian Chair of Mathematics at the University of Cambridge for over 30 years. Hawking achieved worldwide fame for his breakthroughs in theoretical physics and his bestselling books explaining complex concepts to the public. He struggled with amyotrophic lateral sclerosis for over 50 years, becoming almost completely paralyzed but continuing his scientific work using assistive technology to communicate.

 In 2006, together with Thomas
Hertog at CERN, Hawking
proposed a theory based on the
top-down cosmology, according
to which the universe had no
unique initial state

5. PERSONAL STRUGGLE
 fighting a related motor neuron disease amyotrophic lateral sclerosis (ALS)
that their status has worsened over the years, until it is almost completely
paralyzed, and he's forced to communicate through a voice generating device.
 The first symptoms of the disease appeared during his stay in Oxford and finally
was diagnosed with ALS at age 21, just before his first marriage
 At that time the doctors predicted he would not live more than 2 or 3 years
(average survival time of the disease), but for unknown reasons, is one of the
few people who has survived many more years, even suffering the gradual
advance of the disability.
 In 1985 he underwent a tracheotomy and since then uses a voice synthesizer to
communicate. Gradually has lost the use of his limbs and the rest of the
voluntary muscles, including neck strength to keep his head erect, with all this
mobility is negligible.

of head and eyes.
 With voluntary contraction of

phrases into your speech
synthesizer, the worsening state
led him to only be able to
communicate at the rate of one
word per minute.
