19 Black Female Scientists That Have Changed The World
The study of science spans a vast range of subjects, from chemistry and astronomy to coding and medicine. Throughout all of these fields, Black women have made important contributions to both theoretical and practical aspects of science.
In this article, we’ve highlighted some of the top Black female scientists in the United States and the world.
1. Alexa Canady (1950-)
Born in Michigan, Alexa Canady received a degree in zoology from the University of Michigan in 1971. Four years later, she received her medical degree. In 1981, Canady became the first Black female neurosurgeon in the United States.
She specialized in pediatric neurosurgery, and from 1987 until 2001, she was the Chief of Neurosurgery at Michigan’s Children’s Hospital. In 1989, she was inducted into the Michigan Women’s Hall of Fame.
