2. Thomas Jefferson
President: John Adams, 1797-1801
Slave Owner?: Yes. The guy who wrote the Declaration of Independence owned slaves.
Jefferson died precisely fifty years after signing the Declaration of Independence – July 4, 1826. His political rival John Adams died the same day. July 4 generally seems to be a bad day for veeps. Hannibal Hamlin, a vice president under Lincoln, also died on that day.
