Weill Medical College of Cornell University has received $400 million (301 million EUR) for research and treatment of obesity, diabetes, cancer and diseases of aging, among others.
"The goal is to translate the benefits of research advances immediately to patients," the school said in a statement Wednesday.
The gift also will fund a proposed biomedical research building.
The donations bring the medical school halfway toward its $1.3 billion (980 million EUR) capital campaign, started seven months ago.
The money comes from four different sources: Joan and Sanford I. Weill are giving $250 million (188 million EUR); Corinne and Maurice R. Greenberg are contributing $25 million (18.8 million EUR) and another $25 million from their charity, the Starr Foundation; and an anonymous donor is giving $100 million (75.3 million EUR), the school said.
The medical school is named after Sanford I. Weill, the 74-year-old chairman emeritus of Citigroup, who in the past has given the school $200 million.
