Marie Maynard Daly was the first African American woman to earn a Ph.D. in chemistry, in 1947 from Columbia University. She faced a lot of racism and sexism in the scientific world, yet still did important studies on sugars, cholesterols, proteins. Daly also worked on programs to increase the numbers of minority students enrolled in medical school and graduate school for science and created a scholarship fund for black students of science.
