Mae Carol Jemison is an American engineer, physician and NASA astronaut. She became the first African American woman to travel in space when she went into orbit aboard the Space Shuttle Endeavour on September 12, 1992. After medical school and a brief general practice, Jemison served in the Peace Corps from 1985 until 1987, when she was selected by NASA to join the astronaut corps. She resigned from NASA in 1993 to found a company researching the application of technology to daily life. She has appeared on television several times, including as an actress in an episode of Star Trek: The Next Generation. She is a dancer and holds nine honorary doctorates in science, engineering, letters, and the humanities. She is the current principal of the 100 Year Starship organization.

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. "I thought, by now, we'd be going into space like you were going to work." She said it was easier to apply to be a shuttle astronaut, "rather than waiting around in a cornfield, waiting for ET to pick me up or something."

In her childhood, Jemison learned to make connections to science by studying nature. Once when a splinter infected her thumb as a little girl, Jemison's mother turned it into a learning experience. She ended up doing a whole project about pus.[6] Jemison's parents were very supportive of her interest in science, while her teachers were not. "In kindergarten, my teacher asked me what I wanted to be when I grew up, and I told her a scientist," Jemison says. "She said, 'Don't you mean a nurse?' Now, there's nothing wrong with being a nurse, but that's not what I wanted to be." In an interview with Makers, she further explains how her sheer interest in science was not accepted. "Growing up...I was just like every other kid. I loved space, stars and dinosaurs. I always knew I wanted to explore. At the time of the Apollo airing, everybody was thrilled about space, but I remember being irritated that there were no women astronauts. People tried to explain that to me, and I did not buy it."

Jemison says she was inspired by Martin Luther King Jr.; to her King's dream was not an elusive fantasy but a call to action. "Too often people paint him like Santa – smiley and inoffensive," says Jemison. "But when I think of Martin Luther King, I think of attitude, audacity, and bravery." Jemison thinks the civil rights movement was all about breaking down the barriers to human potential. "The best way to make dreams come true is to wake up."

Jemison began dancing at the age of 11. "I love dancing! I took all kinds of dance — African dancing, ballet, jazz, modern — even Japanese dancing. I wanted to become a professional dancer," said Jemison.[11] At the age of 14, she auditioned for the leading role of "Maria" in West Side Story. She did not get the part but Jemison's dancing skills did get her into the line up as a background dancer. "I had a problem with the singing but I danced and acted pretty well enough for them to choose me. I think that people sometimes limit themselves and so rob themselves of the opportunity to realise their dreams. For me, I love the sciences and I also love the arts," says Jemison. "I saw the theatre as an outlet for this passion and so I decided to pursue this dream." Later during her senior year in college, she was trying to decide whether to go to New York to medical school or become a professional dancer. Her mother told her, "You can always dance if you're a doctor, but you can't doctor if you're a dancer."

Jemison graduated from Chicago's Morgan Park High School in 1973 and entered Stanford University at the age of 16. "I was naive and stubborn enough that it didn’t faze me," Jemison said. "It’s not until recently that I realized that 16 was particularly young or that there were even any issues associated with my parents having enough confidence in me to [allow me to] go that far away from home." Jemison graduated from Stanford in 1977, receiving a B.S. degree in chemical engineering and fulfilling the requirements for a B.A. degree in African and Afro-American Studies. At Stanford, she choreographed a musical and dance production called Out of the Shadows. She took initiative to get even further involved in the black community by serving as head of the Black Students Union in college. Jemison said that majoring in engineering as a black woman was difficult because race was always an issue in the United States. "Some professors would just pretend I wasn't there. I would ask a question and a professor would act as if it was just so dumb, the dumbest question he had ever heard. Then, when a white guy would ask the same question, the professor would say, 'That's a very astute observation.'" In an interview with the Des Moines Register in 2008 Jemison said that it was difficult to go to Stanford at 16, but thinks her youthful arrogance may have helped her. "I did have to say, 'I'm going to do this and I don't give a crap (damn).'" She points out the unfairness of the necessity for women and minorities to have that attitude in some fields.

Jemison obtained her M.D. degree in 1981 at Cornell Medical College.[1] She interned at Los Angeles County-USC Medical Center, and in 1982, she worked as a general practitioner. During medical school, Jemison traveled to Cuba, Kenya and Thailand, to provide primary medical care to people living there. During her years at Cornell Medical College, Jemison took lessons in modern dance at the Alvin Ailey school. Jemison later built a dance studio in her home and has choreographed and produced several shows of modern jazz and African dance.

After completing her medical training, Jemison joined the staff of the Peace Corps and served as a Peace Corps Medical Officer from 1983 to 1985 responsible for the health of Peace Corps Volunteers serving in Liberia and Sierra Leone.  Jemison's work in the Peace Corps included supervising the pharmacy, laboratory, medical staff as well as providing medical care, writing self-care manuals, and developing and implementing guidelines for health and safety issues. Jemison also worked with the Center for Disease Control (CDC) helping with research for various vaccines.

Once while serving as a doctor for the Peace Corps, a volunteer became seriously ill, and a doctor diagnosed malaria. The volunteer's condition progressively worsened, and Jemison was sure it was meningitis with life-threatening complications that could not be treated in Sierra Leone. Jemison called for an Air Force hospital plane based in Germany for a military medical evacuation at a cost of $80,000. The embassy questioned whether Jemison had the authority to give such an order, but she told them she did not need anyone's permission for a medical decision. By the time the plane reached Germany with Jemison and the volunteer on board, she had been up with the patient for 56 hours. The patient survived.

After the flight of Sally Ride in 1983, Jemison felt the astronaut program had opened up, so she applied. Jemison's inspiration for joining NASA was African-American actress Nichelle Nichols, who portrayed Lieutenant Uhura on Star Trek. Jemison's involvement with NASA was delayed after the Space Shuttle Challenger disaster in 1986, but after reapplying in 1987, she received the news of her acceptance into the astronaut program. "I got a call saying 'Are you still interested?' and I said 'Yeah'," recalls Jemison,[21] as one of fifteen candidates chosen out of roughly 2,000 applicants.

Her work with NASA before her shuttle launch included launch support activities at the Kennedy Space Center in Florida and verification of Shuttle computer software in the Shuttle Avionics Integration Laboratory (SAIL). "I did things like help to support the launch of vehicles at Kennedy Space Center," said Jemison. "I was in the first class of astronauts selected after the Challenger accident back in 1986, ...  actually worked the launch of the first flight after the Challenger accident.

Jemison flew her only space mission from September 12 to 20, 1992, as a Mission Specialist on STS-47, a cooperative mission between the United States and Japan, as well as the 50th shuttle mission. Jemison was a co-investigator of two bone cell research experiments, one of 43 investigations that were done on STS-47. Jemison also conducted experiments on weightlessness and motion sickness on herself and six other crew members. "The first thing I saw from space was Chicago, my hometown," said Jemison. "I was working on the middeck where there aren't many windows, and as we passed over Chicago, the commander called me up to the flight deck. It was such a significant moment because since I was a little girl I had always assumed I would go into space," Jemison added. Despite NASA's rigid protocol, Jemison would begin each shift with a salute that only a Trekkie could appreciate. "Hailing frequencies open," she could be heard repeating throughout the eight-day mission.

Because of her love of dance and as a salute to creativity, Jemison took a poster from the Alvin Ailey American Dance Theater along with her on the flight. "Many people do not see a connection between science and dance," says Jemison. "but I consider them both to be expressions of the boundless creativity that people have to share with one another." Jemison also took several small art objects from West African countries to symbolize that space belongs to all nations. Also on this flight, according to Bessie Coleman biographer Doris L. Rich, Jemison also took into orbit a photo of Coleman — Coleman was the very first African-American woman to ever fly an airplane.

STS-47 was a cooperative mission between the United States and Japan that included 44 Japanese and United States life science and materials processing experiments. Jemison logged 190 hours, 30 minutes, 23 seconds in space. One of the experiments she supervised on the mission was to induce female frogs to ovulate, fertilize the eggs and then see how tadpoles developed in zero gravity.

Jemison resigned from NASA in March 1993. "I left NASA because I'm very interested in how social sciences interact with technologies," Jemison said. "People always think of technology as something having silicon in it. But a pencil is technology. Any language is technology. Technology is a tool we use to accomplish a particular task and when one talks about appropriate technology in developing countries, appropriate may mean anything from fire to solar electricity." NASA training manager and author Homer Hickam later expressed some regret that she had departed, saying, "NASA had spent a lot of money training her; she also filled a niche, obviously, being a woman of color." Hickam had trained Jemison for her flight on Spacelab-J/STS-47. In an interview with the Des Moines Register on October 16, 2008, Jemison said that she was not driven to be the "first black woman to go into space." "I wouldn't have cared less if 2,000 people had gone up before me... I would still have had my hand up, 'I want to do this.'"

Jemison is a Professor-at-Large at Cornell University and was a professor of Environmental Studies at Dartmouth College from 1995 to 2002. Jemison continues to advocate strongly in favor of science education and getting minority students interested in science. She sees science and technology as being very much a part of society, and African-Americans as having been deeply involved in U.S. science and technology from the beginning. She has been a member of various scientific organizations, such as the American Medical Association, the American Chemical Society, the Association for Space Explorers and the American Association for the Advancement of Science. Additionally, she served on the board of directors of the World Sickle Cell Foundation from 1990 to 1992.

In 1993 Jemison founded her own company, the Jemison Group that researches, markets, and develops science and technology for daily life. Jemison founded the Dorothy Jemison Foundation for Excellence and named the foundation in honor of her mother. "My parents were the best scientists I knew," Jemison said, "because they were always asking questions." One of the projects of Jemison's foundation is The Earth We Share (TEWS), an international science camp where students, ages 12 to 16, work to solve current global problems, like "How Many People Can the Earth Hold" and "Predict the Hot Public Stocks of The Year 2030." The four-week residential program helps students build critical thinking and problem solving skills through an experiential curriculum. Camps have been held at Dartmouth College, Colorado School of Mines, Choate Rosemary Hall and other sites around the United States. TEWS was introduced internationally to high school students in day programs in South Africa and Tunisia. In 1999, TEWS was expanded overseas to adults at the Zermatt Creativity and Leadership Symposium held in Switzerland.

In 1999, Jemison founded BioSentient Corp and has been working to develop a portable device that allows mobile monitoring of the involuntary nervous system. BioSentient has obtained the license to commercialize NASA's space-age technology known as Autogenic Feedback Training Exercise (AFTE), a patented technique that uses biofeedback and autogenic therapy to allow patients to monitor and control their physiology as a possible treatment for anxiety and stress-related disorders. BioSentient is examining AFTE as a treatment for anxiety, nausea, migraine and tension headaches, chronic pain, hypertension and hypotension, and stress-related disorders."

In 2012, Jemison made the winning bid for the DARPA 100 Year Starship project through the Dorothy Jemison Foundation for Excellence. The Dorothy Jemison Foundation for Excellence was awarded a $500,000 grant for further work. The new organization maintained the organizational name 100 Year Starship. Jemison is the current principal of the 100 Year Starship.

In 2018, she collaborated with Bayer and National 4-H Council for the initiative called "Science Matters" which was aimed at encouraging young children to understand and pursue agricultural sciences.

Jemison's first book, Find Where the Wind Goes (2001), is a memoir of her life written for children. She describes her childhood, her time at Stanford, in the Peace Corps and as an astronaut. School Library Journal found the stories about her earlier life to be the most appealing. Book Report found that the "explanation of her encounters with biased professors and their treatment of her on the basis of stereotypes, rather than intelligence, are presented very realistically."

Her "True Book Series," published in 2013, is co-authored with Dana Meachen Rau. Each book in the series has a "Find the Truth" challenge, in which the answer is revealed at the end of the story.[41] School Library Journal found the series to be "properly tantalizing surveys of our local stellar neighborhood and its ongoing exploration."

In 1993, Jemison appeared as Lieutenant Palmer in "Second Chances", an episode of the science fiction television series Star Trek: The Next Generation, earning her the distinction of being the first real-life astronaut to appear on Star Trek. Her appearance came about when LeVar Burton learned from a friend that Jemison was an avid Star Trek fan. Burton asked her if she would be interested in being on the show, to which she responded, "Yeah!!" Jemison had been inspired by the character of Uhura on Star Trek and has been a lifelong fan of the show.

Jemison has also appeared as host and technical consultant of the Discovery Channel science series World of Wonder.

In 2006, Jemison participated in African American Lives, a PBS television miniseries hosted by Henry Louis Gates, Jr., that traces the family history of eight famous African Americans using historical research and genetic techniques. Jemison found to her surprise that she is 13% East Asian in her genetic makeup.

February 2, 2013, Jemison appeared as the "Not My Job" guest on NPR's Wait Wait Don't Tell Me, answering questions about airport shuttles.

In the spring of 1996, Jemison filed a complaint against a Texas police officer, accusing him of police brutality during a traffic stop that ended in her arrest. She was pulled over by Nassau Bay, Texas officer Henry Hughes for allegedly making an illegal U-turn and arrested after Hughes learned of an outstanding warrant on Jemison for a speeding ticket. In the process of arresting her, the officer twisted her wrist and forced her to the ground. In her complaint, Jemison said the officer physically and emotionally mistreated her. Jemison's attorney said she believed she'd already paid the speeding ticket years ago.[59] She spent several hours in jail and was treated at an area hospital after release for deep bruises and a head injury.[61] Jemison said in a televised interview that the incident has altered her feelings about police there. "I always felt safe and comfortable [around the police]. I don't feel that way anymore at Nassau Bay and that's a shame," she said. Jemison filed a lawsuit against the city of Nassau Bay and officer Hughes.

In 2007, diagnostic test provider Gen-Probe Inc. announced that they would not accept the resignation of Jemison from their board of directors. Jemison had failed to be re-elected to the board in a vote of the shareholders of the company at the company's May 31 annual stockholders meeting. The company said it believed that Jemison's failed re-election was the result of a recommendation by advisory firm Institutional Shareholder Services that shareholders vote against her due to her poor attendance at board meetings. Gen-Probe determined that Jemison's two absences in 2006 were for valid reasons and said Jemison had attended all regular and special board and committee meetings since September.

In 2017, a "Women of NASA" LEGO set went on sale featuring (among other things) mini-figurines of Jemison, Margaret Hamilton, Sally Ride, and Nancy Grace Roman.
