Cornelius Vanderbilt and John D. Rockerfeller never had a formal college education, Vanderbilt quitting school and age 11 and Rockerfeller spending several months in a formal bookkeeping course after high school

IIRC, George Stephenson (the guy who invented the railroad) never went to school at all. He started working when he was five years old and had to hire a tutor to learn to read when he was about 20.

"... never went to school at all."

Thank you for pointing that out. And when you go to college these days, depending on what courses you take you will probably get socialist indoctrination anyway.
