Mae Jemison - (Born 1956) Mae Jemison is a retired medical doctor and American astronaut. In 1992, she became the first black woman in space. She holds a degree in chemical engineering from Stanford and a degree in medicine from Cornell. She remains very active in science and technology.

Percy Julian - (1899-1975) Percy Julian developed the anti-glaucoma drug physostigmine.

Dr. Julian was born in Montgomery, Alabama, but educational opportunities for African Americans were limited in the South at that time, so he received his undergraduate degree from DePauw University in Greencastle, Indiana.
