From ThinkWatson.com, Critical Thinkers Through History is a nice visual timeline that show photos or images of some of the greatest critical thinkers in human history.

What do Sigmund Freud, Henry Ford, Frank Lloyd Wright, and Marie Curie have in common? They were great critical thinkers that all made their mark in history! Here’s a chart of some of the top critical thinkers through history. It’s not comprehensive by any means, but see if you agree!

Who else should be on the list?

I think the timeline should go back farther in time, although photos would be a problem.  Sun Tzu, Aristotle, Galileo, etc.

Thanks to Matt for sending in the link!
