Brabazon, an independent writer and film producer, updates his biography of the humanitarian and physician Albert Schweitzer with new and profoundly revealing letters between him and Hlne Bresslau, whom he married after a ten-year correspondence. The letters reveal an intensely secret and unusual relationship, as well as facets of Schweitzer's personality and thinking that he took great trouble to hide from the world. New documents from the State Department regarding his battle with the US Atomic Energy Commission to stop H-bomb tests are also discussed. Annotation c. Book News, Inc., Portland, OR (booknews.com)
