Celebrating the 100th Birthday of a Great Scientist
Is an unquenchable joy in science the secret to longevity?
As a graduate student, Evelyn Witkin jumped up and down with excitement when she found out that bacteria have genes. She went on to spend over half a century studying bacterial genetics, and this month, she turned 100.
Read about the discoveries that earned Witkin a 2015 Lasker Award, view an extended interview in which she discusses her life in science, and see a New York Times profile on her.
