Why this person is recognized
What Mae has actually done
Recognition rests on documented conduct. Each example below records what happened, when, the principle it demonstrates, and the sources our editors reviewed, with an honest assessment of how strong that evidence is.
- 1
Served as Peace Corps Area Medical Officer for Sierra Leone and Liberia
From January 1983 to June 1985, after medical school and an internship, Jemison worked in Sierra Leone and Liberia as Area Peace Corps Medical Officer. She managed health care delivery for Peace Corps and U.S. Embassy personnel, supervised the pharmacy, laboratory and medical staff, and developed health training and public health guidelines. She also took part in research on a hepatitis B vaccine, schistosomiasis and rabies with the National Institutes of Health and the Centers for Disease Control.
Principle demonstrated: Public service to others at personal cost

Ordered a costly military medical evacuation for a gravely ill volunteer despite challenges to her authority
In her own published account, Jemison, then 26, concluded that a Peace Corps volunteer whose condition did not match a malaria diagnosis had meningitis and called for a military medical evacuation that she said cost $80,000 to initiate. She wrote that embassy staff questioned whether she had the authority and that she told them she needed no one's permission; she stayed with the patient for 56 hours and the patient survived. She has repeated the account consistently, including in a 2017 interview.
Principle demonstrated: Principled decision under pressure for a vulnerable person

Left NASA after one flight to found a company focused on technology for the developing world
Jemison resigned from NASA in March 1993, six months after her only spaceflight, and the same month founded the Jemison Group, a technology consulting firm. The National Library of Medicine describes the company as formed to develop technologies for the developing world, with projects including a satellite-based telecommunications system to improve health care in West Africa and consulting on solar thermal electricity for developing countries. She later taught a Dartmouth course on space-age technology in developing countries and founded the Jemison Institute there.
Principle demonstrated: Consistency between stated values and conduct

Founded The Earth We Share science camps in 1994 and remained hands-on for decades
In 1994 Jemison founded the Dorothy Jemison Foundation for Excellence, named for her mother, and its The Earth We Share international science camp for students aged 12 to 16. The Cornell Chronicle reported in 2005 that she visited the four-week camp at Cornell in person twice, returning for a day to check students' progress, and watched the final presentations remotely from China. She has described her role as chief curriculum developer, including training teachers and trainers.
Principle demonstrated: Sustained, hands-on contribution to young people's education

Testified before the U.S. Senate on barriers facing girls and minorities in science
On June 19, 2012, Jemison submitted written testimony to the Senate Committee on Health, Education, Labor and Pensions for a hearing marking the 40th anniversary of Title IX. She argued that women and minority students are pushed out of STEM fields by biased teaching, discouragement and stereotypes rather than lack of ability, described her own experience as the only girl in her high school drafting class and with skeptical engineering professors at Stanford, and called for continued enforcement of Title IX.
Principle demonstrated: Fairness and inclusion; using influence on behalf of those with less

Character dimensions
The five dimensions
We assess conduct against five dimensions. A dimension marked "not independently assessed" means we did not review documentation for it; it is never a negative finding. We do not assign scores.
Relationship Integrity
Not independently assessedNo independent documentation reviewed; not assessed.
Personal Integrity
DocumentedHer career choices are consistent with her stated values: she left NASA in 1993 to apply technology to developing-world needs and has run a science literacy program for 30 years. In 1996 she filed a formal complaint about her treatment during a traffic-warrant arrest through official channels; the investigation cleared the officer (see concerns). No instance of dishonesty found.
Professional Integrity
Not independently assessedPhysician, Peace Corps medical officer, NASA mission specialist (co-investigator on a bone cell experiment on STS-47), Dartmouth professor, corporate board member, and principal of the DARPA-seeded 100 Year Starship project (2012). In 2012 she said she wanted the starship effort to draw participation "from everyone, regardless of ethnicity, gender, geographical location or scientific field." No adverse workplace findings located.
Moral Courage
Partially documentedThe Peace Corps evacuation decision is the clearest instance, but it is self-reported. Her Senate testimony and public statements about bias in STEM education are documented but low-cost advocacy.
Respect for Others
DocumentedStrongest dimension: two and a half years of frontline medical service in West Africa and three decades of hands-on science education for 12 to 16 year olds, with independent reporting of her in-person involvement.
Recognition rationale
Why the standard was met
Mae Jemison met the standard through public service that predates and outlasts her spaceflight. She served two and a half years as a Peace Corps medical officer in Sierra Leone and Liberia before joining NASA, left the agency after one flight to apply technology to developing-world needs, founded The Earth We Share science camps in 1994 and remained personally involved for decades, and testified before the United States Senate in 2012 on barriers facing girls and minorities in science. The conduct is documented by NASA's own biography, public records, and independent reporting of her in-person involvement. One example, a costly medical evacuation she ordered in 1983 over objections, is self-reported and is rated accordingly. The only adverse matter found is a 1996 traffic-warrant arrest in which the disputed conduct concerned the officer, not her; it is not a finding against her. Recognition rests on a lifetime of service to people with less power than herself, not on her mission.
Professional biography
Career context
Mae Jemison earned a chemical engineering degree from Stanford in 1977 and an M.D. from Cornell in 1981, then served as Area Peace Corps Medical Officer for Sierra Leone and Liberia from January 1983 to June 1985. Selected by NASA in June 1987, she flew as science mission specialist on STS-47 in September 1992 and left NASA in March 1993. She founded the Jemison Group, the Dorothy Jemison Foundation for Excellence and its The Earth We Share science camps, taught environmental studies at Dartmouth, and leads the 100 Year Starship initiative.
