In 1970, Margaret Truman and bestselling author Thomas Fleming spent eight days with her father, President Harry Truman, as part of their research for a biography of the 33rd president of the United States. Mr. Truman had personally chosen Fleming as Margaret’s collaborator. He had read and admired his biography of Thomas Jefferson, The Man From Monticello. Here’s Fleming’s memoir of that amazing time, during which the elder statesman sets the record straight on John Kennedy, Lyndon Johnson, Joseph Stalin, Charles de Gaulle, Douglas MacArthur, the atomic bomb, and, most important, the American presidency.
