Paul Farmer

Dr. Farmer worked to improve health care in the developing world. He died in Rwanda Feb. 21, on the grounds of a hospital and university he helped establish. Originally broadcast in 2011.

The physician and anthropologist has spent 30 years treating patients in Haiti. In Haiti After The Earthquake, he details what it was like on the ground in the days after the 2010 quake — and why the country is still struggling to recover.

Farmer is an infectious disease specialist and a recipient of the MacArthur "genius" grant for his work treating tuberculosis in Haiti. He is the subject of the new book Mountains Beyond Mountains, by Pulitzer Prize-winning author Tracy Kidder.
