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". He collaborated with Kennedy on the book Profiles in Courage, "assembling and preparing" much of the research on which the book was based. Kennedy won the 1957 Pulitzer Prize for Biography. Sorensen helped draft Kennedy's inaugural address and Lyndon Johnson's Let Us Continue speech following Kennedy's assassination, and was the primary author of Kennedy's 1962 "We choose to go to the Moon" speech.
