He won a Pulitzer Prize
Two novels about World War Two were penned by JFK. At the age of 22, Kennedy published his first book, "Why England Slept," and in 1945, he worked for William Randolph Hearst's newspapers as a reporter for a few months, covering the United Nations convention in San Francisco and the aftermath of World War II in Europe.
John F. Kennedy, a senator from Massachusetts, received the Pulitzer Prize for Biography on May 6, 1957, for his book "Profiles in Courage." Kennedy gained national prominence thanks to the effort, which received high praise. One of the most important books ever written on political courage and the U.S. Senate, despite some controversy surrounding the book's authorship (some claim that Kennedy speechwriter Ted Sorensen wrote the book) and the accuracy of some of the characterizations (Blanche Ames*, the daughter of Governor Adelbert Ames, tried unsuccessfully to get a retraction on the negative description of her father).
Due to back surgery, Senator Kennedy spent the years 1954–1955, confined to bed. During this time, the research and planning for the book that would later win an award were completed.
