James Watson, left and Francis Crick, right, the young co-discoverers of DNA's double-helix structure, in Cambridge, England, 1953. The brash duo were impatient with authority, dismissive of prevailing opinions -- and very eager to win the race to unravel the code. "A goodly number of scientists," said Watson, "are not only narrow-minded and dull, but also just stupid."
Picture - With a Model of DNA: At 35, the British Crick had not yet earned his Ph.D., while the American Watson, 12 years younger, was awarded his doctorate when he was just 22.
After the two published the findings of their remarkable discovery in
1953, Watson returned to the United States to teach at Harvard. Crick went
on to become a professor at the Salk Institute for Biological Studies in
San Diego, California.
