First woman full professor at Mount Sinai School of Medicine

In 1973, Tsai-Fan Yu became the first woman to be appointed a full professor at the Mount Sinai School of Medicine (now Icahn School of Medicine at Mount Sinai). While the exact calendar date of the promotion is not reported, the year is firmly documented across multiple sources and represents a major barrier‑breaking milestone.

Mount Sinai was one of the oldest and most prestigious teaching hospitals in the United States, with a faculty historically dominated by men. Yu’s elevation to full professor acknowledged decades of pioneering research on gout, including elucidating its metabolic basis in elevated uric acid and developing effective treatments such as probenecid, colchicine, and allopurinol. Her promotion signaled institutional recognition that a Chinese‑born woman scientist could lead a major research program and train future specialists on equal footing with male colleagues.

For women in academic medicine, this first was highly significant. At a time when few medical schools had any women full professors, Yu’s appointment challenged assumptions about who could hold senior academic authority. It created a precedent within Mount Sinai for future women faculty and contributed to broader efforts to diversify leadership in U.S. medical education.

From the perspective of women’s history and the history of science, Yu’s 1973 promotion stands as a landmark in both gender equality and the globalization of medical expertise, demonstrating how a woman immigrant researcher could reshape an institution and a clinical field.
