Andrew and Stephen C. Schlesinger discuss The Letters of Arthur Schlesinger, Jr., a collection of their father’s letters to Harry Truman, Robert Kennedy and others, in a recent appearance on MSNBC’s “Morning Joe.”

Here’s a summary of the book:

The Letters of Arthur Schlesinger, Jr. reveals the late historian’s unvarnished views on the great issues and personalities of his time, from the dawn of the Cold War to the aftermath of September 11. Here is Schlesinger’s correspondence with such icons of American statecraft as Harry Truman, Adlai Stevenson, Hubert Humphrey, Henry Kissinger, Bill Clinton, and, of course, John and Robert Kennedy (including a detailed critique of JFK’s manuscript for Profiles in Courage). There are letters to friends and confidants such as Eleanor Roosevelt, John Kenneth Galbraith, Gore Vidal, William Styron, and Jacqueline Kennedy (to whom Schlesinger sends his handwritten condolences in the hours after her husband’s assassination), and exchanges with such unlikely pen pals as Groucho Marx, Sammy Davis, Jr., and Bianca Jagger. Finally, there are Schlesinger’s many thoughtful replies to the inquiries of ordinary citizens, in which he offers his observations on influences, issues of the day, and the craft of writing history.
