Joseph Grafton Gall (born 1928) is an American cell biologist and winner of the 2006 Albert Lasker Special Achievement Award. He also won the 2007 Louisa Gross Horwitz Prize (Columbia University) (shared with Elizabeth Blackburn and Carol W. Greider). He has been credited for encouraging women biologists, a group sometimes called "Gall's Gals", in an era when this was relatively uncommon. One of his students who went on to do important work in the science include Susan Gerbi. When asked to explain his encouragement of women in the sciences, he "began talking about his mother. Gifted in math and science, she had been the first woman in her family to attend college, graduating in the 1920s. She became a homemaker, not a scientist. But she urged a young Gall to explore the natural world, encouraging him to catch bugs and bring them into the house so together they could identify the creatures using scientific reference books. "It never occurred to me that a woman's aptitude was different than a man's," Gall said. "My father -- a lawyer -- was afraid of animals and insects. So, if anything, maybe I thought it went the other way.".
