When I was a student studying to become a Psychotherapist, I wanted to understand how the various important figures in the development of theoretical models might have come across each other, met each other, and been influenced by each others' works. I could not find anything that I thought matched what I was seeking, and so I created this for myself. Hyperlinks on page-1 take you to a detailed page on each name :-)
