Francis Crick, Nobel Prize winner in Biology, who co-discovered the DNA double helix with Jim Watson, died today. I grew up admiring people like Watson and Crick, Feynman, Bardeen (Yes, I was/am a science geek at heart!), Fermi and Landau. At the time, Watson and Crick were the “young ones” of this group; today Crick is dead at 88. A real character, he recognized the serendipity of his discovery, but continued making scientific contributions during his lifetime, including generalizations about the role of DNA in all species. A sad day for science, his contributions will always be remembered. In some sense, his death marks in my mind the end of an era in science which was both an important part of and a significant influence in my life.
