If you would like to see a comprehensive list of famous homeschoolers, broken down by occupation, check out this site: http://www.famoushomeschoolers.net/index.html
The site is owned by a homeschooling mother and librarian named Teri Ann Berg Olsen. It appears that she was the original author of the list of famous homeschoolers that is now floating around the internet (without giving credit to her unfortunately). She has been continually updating the list since 2000, so there are a LOT of names!
For a great list of famous self-educated people, see this site: http://autodidactic.com/profiles/profiles.htm
If you see anyone interesting on these lists, I highly recommend reading their biography. It is so comforting to know that even great people are perfectly ordinary, with ordinary problems just like you. It will give you courage – especially if you’re questioning your decision to home school!
