Millions of Americans spend the early morning hours of New Year's Day watching the Rose Parade wind its way through the streets of Pasadena under typically blue California skies. The floral floats and marching bands always pass the Norton Simon Museum, the name clearly visible for all to see. But few of the bleary-eyed viewers have ever visited one of the world's great art collections, and fewer know the man behind the name, for outside of art Norton Simon was a very private mogul. Norton Simon achieved success in two disparate, at times contradictory, worlds -- commerce and culture. His achievements were unrivaled except, perhaps, by personal demons, an exchange few of us would be willing to make.
