The second edition of this biography of humanitarian Albert Schweitzer has been updated to include documents discovered since the work was originally written, including the letters between Schweitzer and Helene Bresslau written during the ten years before their marriage. This correspondence tells of a complicated love story and throws a completely new light on Schweitzer’s personality and the genesis of his decision to go to Africa. The author’s ongoing research has also included more recently released documents from the State Department regarding Schweitzer’s battle with the United States Atomic Energy Commission to halt H-bomb tests.
