1980s -- Dr. Patricia Bath was born in Harlem, N.Y. in 1942. Bath earned a B.A. in chemistry from New York's Hunter College in 1964, and a doctoral degree from Howard University in 1968. As an intern at Harlem hospital Bath's noticed disparities in the number of eye procedures performed on Black and low income patients despite the high cases of blindness among the communities. She later persuaded her professors at Columbia University to perform free eye procedures on Harlem Hospital patients, and in 1970 became the first black person in her field to serve in ophthalmology at New York University.
