Charles M. Schwab (1862-1939)

He and his wife died without children, but they raised her nephew, Carlton Wagner, and he had a daughter by a nurse who he saw twice a year and put up in a fine hotel in Washington D.C. with a chauffeur and a companion. Knowing how Carnegie would frown on his extra-marital affair, he was unable to formally adopt his daughter. In 1918, he came in at thirteenth (tied with James Stillman, Daniel Guggenheim, Thomas F. Ryan and J.P. Morgan, Jr.) on the first ever Forbes Rich List with an estimated personal fortune of $70-million but by the time of his death in 1939 in was significantly debt and living in comparative poverty.
