Greatest Figures in American History

John Hawkins at Right Wing News asked several left-of-center bloggers, including yours truly, to send him a list of who we think are the 20 greatest figures in American history.
Rather than invent objective criteria I decided to just cite my favorites. My list doesn’t include 20. It only includes 16. That’s how many I came up with in one sitting and I didn’t want to force four more.
Here they are in no particular order and for no particular reason. Feel free to use the comments and offer suggestions for those I left out.
1. Franklin Delano Roosevelt
2. Theodore Roosevelt
3. Eleanor Roosevelt
4. Abraham Lincoln
5. George Washington
6. Rosa Parks
7. Thomas Jefferson
8. John Muir
9. Mark Twain
10. Harry S Truman
11. Martin Luther King Jr.
12. Susan B. Anthony
13. John Steinbeck
14. Frederick Douglass
15. Harriet Tubman
16. Carl Sagan
