Dr. Étienne-Émile Baulieu, the groundbreaking French endocrinologist whose research yielded the widely used abortion medication mifepristone, has passed away at his Paris residence at age 98. His death was confirmed by his wife, Simone Harari Baulieu, on April 12th.

Baulieu’s most enduring legacy stems from his pivotal role in developing mifepristone—initially codenamed RU-486—during the 1980s. This oral medication transformed reproductive healthcare by providing a non-surgical, accessible termination option. To date, it has been utilized by millions worldwide, particularly in regions lacking advanced medical facilities.

In a heartfelt tribute, Simone Baulieu highlighted her husband’s unwavering ethos: "His scientific pursuits were fueled by a commitment to human progress, advocacy for women’s autonomy, and a vision for longer, healthier lives." French President Emmanuel Macron memorialized Baulieu as "a beacon of courage" on social media, emphasizing how the scientist’s "progressive mind liberated women." Gender Equality Minister Aurore Bergé similarly praised his lifelong dedication to "human dignity."

From Resistance Fighter to Medical Revolutionary

Born Étienne Blum in Strasbourg (1926), Baulieu adopted his wartime alias while joining the French Resistance against Nazi occupation at just 15. His academic journey later took him to the United States, where he collaborated with Dr. Gregory Pincus—a key architect of the first contraceptive pill. Pincus steered Baulieu toward endocrine research, inspiring his focus on reproductive hormones.

Returning to France, Baulieu pioneered a mechanism to inhibit progesterone, the hormone crucial for embryo implantation. By blocking its action, mifepristone safely terminates early pregnancies. Though developed within a decade, its approval ignited global backlash. Baulieu spent years advocating for regulatory acceptance amidst vehement opposition, death threats, and comparisons to "Nazi scientists" by anti-abortion groups.

A Legacy Marked by Controversy and Progress

France authorized mifepristone in 1988, but the U.S. delayed approval until 2000—and access remains contentious. Over 100 nations now permit the drug, yet restrictions persist in several U.S. states. When Wyoming banned it in 2023, Baulieu decried the move as undermining "women’s freedom."

Despite claims by critics labeling medication abortion "dangerous," data underscores its safety. The U.S. FDA reports only 36 fatalities linked to mifepristone out of 5.6 million uses (≈0.65 deaths per 100,000). By contrast, routine aspirin use carries a mortality rate of 15.3 per 100,000. The World Health Organization added the drug to its Essential Medicines List in 2010, affirming its medical necessity.

Baulieu’s later research targeted Alzheimer’s prevention and depression treatments. In 2023, President Macron awarded him France’s highest honor—the Grand Cross of the Legion of Honour—hailing his resilience: "Amid vile insults, you stood firm for science and liberty."

His death marks the close of a life dedicated to medical emancipation, leaving a profound imprint on global healthcare equity and women’s rights.
