The editors at Humboldt High School in St. Paul, Minn., had Joan Mansfield’s number. “Though other blondes may fade and tire, Joan will set men’s hearts afire,” read her entry in the Class of 1945 yearbook.

Indeed, Joan, a member of the drama club, would go on to generate a good deal of drama, embarking on a scandalous affair with one of America’s richest men and marrying him. Then, long before Warren Buffett and Bill Gates made such pledges common, she would give away the bulk of his $3 billion fast-food fortune.
