First major North American proponent of the tomato, inventor of the swivel chair, father of archeology--there's a lot of stuff there. He was about as prolific as Franklin.
Yeah, but everyone knows about that stuff. (Maybe not the architecture.) He also founded the University of Virginia. But his more "hackerly" accomplishments are among the less historically noteworthy ones.
He was personally very disappointed in his presidency, despite all the accomplishments you note, plus winning the First Barbary War. He was in many ways a frustrated idealist, most dramatically in his moral disgust at slavery contrasted with his lifelong ownership of slaves.
