Background
Mae Carol Jemison was born on October 17, 1956, in Decatur, Alabama, United States. She is the youngest child of Charlie Jemison, a roofer, carpenter, and maintenance supervisor for a charity organization, and Dorothy Green, an elementary school teacher. Her sister, Ada Jemison Bullock, became a child psychiatrist, and her brother, Charles Jemison, is a real estate broker. The Jemison family moved to Chicago, Illinois, when Jemison was three years old to take advantage of better educational opportunities, and it is that city that she calls her hometown. Throughout her early school years, Jemison's parents were supportive and encouraging of her talents and abilities, and she spent a considerable amount of time in her school library reading about all aspects of science, especially astronomy.
