Clement Stone, who parlayed $100 in savings into an insurance empire that financed millions of dollars of contributions to the campaigns of Richard M. Nixon and hundreds of millions to charities, died on Tuesday in Evanston, Ill. He was 100 and lived in Winnetka, Ill.... William Clement Stone was born in Chicago on May 4, 1902. His father died when he was 3, leaving the family impoverished by gambling losses. At the age of 6, he began hawking newspapers on Chicago's South Side, while his mother worked as a dressmaker. At 13, he owned his own newsstand.”
