Picasso's Childhood Facts

John Harvey Kellogg, doctor: The man who started Kellogg's brand cereal � and all their eventual offshoot products � was a doctor before he became an entrepreneur. Inspired by his commitment to health and nutrition, Kellogg was the chief physician at the Western Health Reform Institute of Battle Creek, which promoted healthy eating and a healthy lifestyle. He had nontraditional health beliefs, though: he was convinced most illnesses were caused by bowel irregularity and/or stomach disorders, or by sex (he often claimed that he and his wife of 40 years had never consummated their marriage). A health book author and lecturer, Kellogg and his brother started the Kellogg cereal company and invented wheat and corn flakes, virtually on accident, due to budget constraints and a batch of overcooked dough.

Harry Truman, haberdasher:
The president who dropped the A-bomb had much more humble beginnings. He was a bank clerk and bookkeeper, served in the National Guard and in WWI, and after the war, opened his own men's haberdashery store in Kansas City, MO, with a friend.

Graham Chapman, doctor:
Before Monty Python success, Chapman wrote for the BBC and worked on radio and TV series, with John Cleese and other future collaborators. But even before the entertainment business, the British actor and writer studied at the Barts and The London School of Medicine and Dentistry. He met Cleese at this time, and together, the two wrote sketches together. While some sources say that Chapman did not practice medicine professionally, others say that he was a doctor for a few years before turning to show business full time.
