Celebrated humanitarian, theologian and philosopher Albert Schweitzer turned to medicine at age 30, after a successful career in music. As a physician and Christian missionary, he dedicated himself to the hospital that he set up in French Equatorial Africa (now Gabon) for the treatment of various ailments including leprosy and sleeping sickness. He was awarded the Nobel Prize for peace in 1952 for his service to humanity. Though he periodically returned to Europe for fundraising purposes, Schweitzer lived in Africa from 1913 until his death.
