William George Helis Sr. (October 17, 1886 - July 25, 1950) was an impoverished Greek emigrant to the United States who made a fortune in the oil business and who became a major owner/breeder of Thoroughbred racehorses and racetrack owner. In his obituary, the Pittsburg Press called William Helis "one of the amazing figures of the American oilfields."[1]
A resident and legal domicile of New Orleans, Louisiana,[2] William Helis died at Johns Hopkins Hospital in Baltimore, Maryland. His remains were brought home to New Orleans where he was interred in the Metairie Cemetery.[3] His mausoleum was built by American architect and sculptor, Albert Weiblen.[4]
In 1991, William Helis was posthumously inducted into the Fair Grounds Racing Hall of Fame.[5]
William George Jr. became managing partner of his father's various oil properties and was also heavily involved in Thoroughbred horse racing.
