Yvonne S. Thornton is an American obstetrician-gynecologist, musician and author.

Biography Thornton was born in New York City and raised in Long Branch, New Jersey as the third of five children to Donald (1925-1983) and Itasker Thornton (1915-1977), where she graduated from Long Branch High School. Her father, a ditchdigger, and a veteran of World War II, had a dream for each of his six children, all African-American girls, to become doctors.

Thornton served on active duty in the United States Navy Medical Corps from 1979 to 1982. She was commissioned with the rank of Lieutenant Commander and served as an obstetrician–gynecologist during her tenure.

Thornton was stationed at the National Naval Medical Center in Bethesda, Maryland now part of the Walter Reed National Military Medical Center.

In 1996, Thornton received her Masters in Public Health degree in Health Policy and Management from Columbia University School of Public Health. She eventually rose to the rank of full professor and was appointed to the faculty of Weill Cornell Medical College as a Professor of Clinical Obstetrics and Gynecology in 2003. She now holds the faculty position of Professor Emeritus of Obstetrics and Gynecology at New York Medical College. and was lead vocalist while her youngest sister, Rita, played piano and keyboards. Their father, Donald, was the road manager.

At age 11, The Thornton Sisters performed on the then-popular Ted Mack and the Original Amateur Hour. Their performance appears in the Motion Picture, Broadcasting and Recorded Sound Division of the Library of Congress

Two years later, the sextet went on to win an unprecedented six consecutive weeks on Amateur Night at Harlem's world famous Apollo Theatre. The coveted prize was a paid week of appearances with professional artists, such as Shep and the Limelites, Fats Domino, and Ernie K-Doe. A year later, in 1962, The Thornton Sisters were featured at The Brooklyn Fox with Murray the "K" and his Swingin' Soiree, performing with Fabian, The Shirelles, Chuck Jackson, and The Four Seasons.

During that year, The Thornton Sisters signed with Roulette Records and then Atlantic Records. However, the mandated personal appearance tours conflicted with their academic pursuits and the contracts were canceled.

After the Brooklyn Fox, for the next thirteen years (1963-1976), The Thornton Sisters were on the “college circuit” performing on weekends at many fraternities and eating clubs of many colleges, including Amherst, Colgate and Bucknell and Ivy League universities, such as Princeton, Cornell, Dartmouth and University of Pennsylvania in order to defray the cost of their tuition for medical and dental schools.

Awards and honors Thornton has received numerous honors over the years, including several honorary doctorate degrees. Her second memoir, Something to Prove: A Daughter's Journey to Fulfill a Father's Legacy, was released in December 2010 and was named the Grand Prize Winner of the 2011 New York Book Festival.

Research and scholarly contributions Yvonne S. Thornton is a perinatologist whose clinical research and academic work have significantly influenced maternal-fetal medicine, prenatal diagnostics, and obstetric care.

Prenatal diagnostics and chorionic villus sampling (CVS) Thornton is known for her instrumental role in refining and advocating for chorionic villus sampling (CVS), a prenatal diagnostic technique that allows early detection of genetic conditions in the fetus, typically in the first trimester. She led clinical trials at Cornell University and collaborated with Thomas Jefferson University to master and teach the procedure. She conducted research on interventions for obesity in pregnancy, including the field's first randomized clinical trial on perinatal outcomes in nutritionally monitored obese women, addressing weight gain prevention and associated maternal-fetal complications.

She also developed practical obstetric innovations, such as the "Thornton Suspenders", a suspension technique for safely delivering morbidly obese patients. Her research emphasized evidence-based, patient-centered care in challenging clinical scenarios.

Academic leadership and publications Thornton has authored numerous scholarly and educational works, including:

Textbooks: Primary Care for the Obstetrician and Gynecologist Lay and professional books: Woman to Woman and Inside Information for Women

Her scholarly contributions extend beyond the clinic through mentorship and teaching at institutions such as New York Medical College, Westchester Medical Center, Morristown Memorial Hospital, and Columbia University, where she has guided generations of medical students and residents in maternal-fetal medicine.
