A world traveler and self-made millionaire, Mary Hudson was one of only three women on Forbes Magazine's list of 400 richest Americans. As an oil industry leader listed in the World's Who's Who of Women, she made international news when her empire collapsed. Hudson’s career began in 1933, as a 21-year-old widow with an infant to support. She borrowed $200 to buy a gas station in Kansas City, which led to a prominent role in a man's industry. An in-your-face independent distributor, among the first to offer no-frills, self-service gasoline, she co-founded a national organization for independent dealers.
