Did jfk write his own speeches?

Although JFK is known for being an excellent public speaker, it is unclear how much of his speeches were actually written by him. In some cases, it is known that he had help from speechwriters, such as Ted Sorensen. In other cases, JFK is known to have written his own speeches, such as his famous Inaugural Address. It is difficult to determine exactly how much JFK wrote himself, as many of his speeches are simply credited to " Kennedy." However, it is clear that he was an excellent speechwriter, and often came up with his own material. In fact, many of his famous quotes are actually from his speeches.
