I found a few :) I’ll post them in a moment.
Thank you! Yes, JFK published 3 novels (to my knowledge):
1) Why England Slept (thesis JFK wrote during his senior year at Harvard)
2) A Nation of Immigrants (published in 1964, after JFK’s death, though written in 1958)
3) Profiles in Courage (his most famous book, which won the Pulitzer Prize)
JFK gave many amazing speeches in his time. Below is a link to a list of his speeches:
Hope this helps you some :)
