BOSTON — Dr. Paul Farmer, a U.S. physician, humanitarian and author renowned for providing health care to millions of impoverished people worldwide and who co-founded the global nonprofit Partners in Health, has died. He was 62.

The Boston-based organization confirmed Farmer’s death on Monday, calling it “devastating” and noting he unexpectedly passed away in his sleep from an acute cardiac event while in Rwanda, where he had been teaching.

Farmer was a professor of medicine at Harvard Medical School and chief of the division of global health equity at Brigham and Women’s Hospital. He wrote extensively on health, human rights and social inequality, according to Partners in Health.

“A compassionate physician and infectious disease specialist, a brilliant and influential medical anthropologist, and among the greatest humanitarians of our time — perhaps all time — Paul dedicated his life to improving human health and advocating for health equity and social justice on a global scale,” wrote George Q. Daley, dean of Harvard University’s Faculty of Medicine, in a statement.

Partners in Health, founded in 1987, said its mission is “to provide a preferential option for the poor in health care.” The organization began its work in Cange, a rural village in Haiti’s central plateau, and later expanded its operations to regions including Africa, Eastern Europe and Latin America.
