Mae Carol Jemison was born in Decatur, Alabama, on October 17, 1956, the youngest child of Charlie Jemison and Dorothy Green. Her father was a maintenance supervisor for a charity organization, and her mother worked most of her career as an elementary school teacher of English and math at the Beethoven School in Chicago. The family moved to Chicago, Illinois, when Jemison was three years old, to take advantage of the better educational and employment opportunities there. Jemison says that as a young girl growing up in Chicago she always assumed she would get into space.

Jemison is an active public speaker who appears before private and public groups promoting science and technology as well as providing an inspirational and educational message for young people. "Having been an astronaut gives me a platform," says Jemison,"but I'd blow it if I just talked about the Shuttle." Jemison uses her platform to speak out on the gap in the quality of health-care between the United States and the Third World. "Martin Luther King [Jr.] ... didn't just have a dream, he got things done."  Jemison sometimes appears at charity events. In 2007, Jemison walked the runway, wearing Lyn Devon, at the Red Dress Heart Truth fashion show during Fashion Week in New York to help raise money to fight heart disease. Also in 2007, in May, Jemison was the graduation commencement speaker and only the 11th person in the 52-year history of Harvey Mudd College to be given an honorary degree. She was awarded a doctor of engineering degree.  On February 17, 2008, Jemison was the featured speaker for the 100th anniversary of the founding of the Alpha Kappa Alpha Sorority. Jemison paid tribute to Alpha Kappa Alpha by carrying the sorority's banner with her on her shuttle flight. Jemison's space suit is a part of the sorority's national traveling Centennial Exhibit. Jemison is an honorary member of Alpha Kappa Alpha, a sorority founded in 1908 at Howard University to address the social issues of the time and promote scholarship among black women. The Des Moines Register interviewed Jemison on October 16, 2008 and reported that she has mixed feelings about the term "role model". "Here's the deal: Everybody's a role model.... Role models can be good or bad, positive or negative."  Jemison participated with First Lady, Michelle Obama, in a forum for promising girls in the Washington, D.C. public schools in March 2009. In 2014, Jemison also appeared at Wayne State University for their annual Dr. Martin Luther King, Jr. Tribute Luncheon. In 2016, she partnered with Bayer Corporation to promote and advance science literacy in schools, emphasizing hands-on experimentation.  She took part in the Michigan State University's lecture series, "Slavery to Freedom: An American Odyssey," in February 2017. In May 2017, Jemison gave the commencement speech at Rice University. She discussed the 100 Year Plan, science and education and other topics at Western Michigan University also in May 2017.
