Theodore Chaikin Sorensen (May 8, 1928 – October 31, 2010) was an American lawyer, writer, and presidential adviser. He was a speechwriter for President John F. Kennedy, as well as one of his closest advisers. President Kennedy once called him his "intellectual blood bank". Most notably, he was generally regarded as the author of Profiles in Courage, and stated in his memoir that he helped write the book. Profiles in Courage won Kennedy the 1957 Pulitzer Prize for Biography. Sorensen helped draft Kennedy's inaugural address and was also the primary author of Kennedy's 1962 "We choose to go to the Moon" speech.
