Bill Gates has called Paul Farmer one of the most amazing people he has ever met. CNN medical correspondent Dr. Sanjay Gupta says that "if pure altruism exists in humans, it probably looks a lot like Dr. Paul Farmer."

In Paul Farmer, Servant to the Poor, Jennie Weiss Block introduces readers to this physician and medical anthropologist of international stature whose Catholic faith has driven him to work untiringly to make a preferential option for the poor in health care. Farmer, with his colleagues at Harvard University and Partners in Health, have been instrumental in bringing the fruits of modern medicine to millions of the poorest people in the world, in places like Haiti, Rwanda, Peru, Russia, Malawi, and West Africa during the recent Ebola crisis. Challenging the conventional wisdom of global health experts, Dr. Farmer has shown it is possible to deliver high-quality medical care on a large scale in settings of great poverty and to build communities around the globe where good health and hope prevail.
