![]() There, he met Francis Crick, with whom he shared a fascination with genetics and inheritance. Convinced that he needed to learn tools of physics and chemistry in order to uncover the structure of DNA, he moved abroad to the Cavendish Laboratory at the University of Cambridge in the United Kingdom. ![]() For his graduate work, Watson used X-rays to inactivate bacterial viruses and earned his Doctor of Philosophy at age 22. Although the conventional view of the time was that proteins were genes and able to replicate themselves, Luria and his colleagues were aware of studies suggesting that DNA, not protein, was the genetic mastermind. ![]() Luria was a member of the Phage Group of investigators who used bacterial viruses as a tool to investigate genes. ![]() Watson completed his Bachelor of Science in Zoology in 1947 at the University of Chicago and began graduate work in the genetics laboratory of Salvador Luria at Indiana University, Indiana. His life ambition changed, however, after reading the book What is Life by Erwin Schrödinger, which convinced him to trade in his binoculars for a microscrope to study genetics instead. He grew up an avid bird watcher and planned to be an ornithologist. James Dewey Watson was born in Chicago in Illinois, United States, on 6 April 1928, the son of a businessman tailor. ![]()
