What is the name of book jfk wrote?

John F. Kennedy did not write a book under his own name. He did, however, write a book of essays called "Profiles in Courage" which was published in 1956.

However, it's important to note that there are strong suspicions that the book was not entirely written by Kennedy, but instead was largely ghostwritten by Theodore Sorensen, a close advisor and speechwriter. This is a subject of debate among historians and biographers.
