Scientist Leona Zacharias was a rare woman. She graduated from Barnard College in 1927 with a degree in biology, followed by a Ph.D. from Columbia University. But throughout her career she labored behind men with loftier titles who got the bulk of the credit. In the 1940s, when premature newborns were going blind after being born with perfectly healthy eyes, Dr. Zacharias was part of the team that worked to root out the cause.
