Lewis Solon Rosenstiel (21 July 1891 – 21 January 1976) was the founder of Schenley Industries, an American liquor company, and a philanthropist.
He began his career working at his uncle's business, Susquemac Distilling Company, in Milton, Kentucky.
The company bought numerous distillers, including one in Schenley, Pennsylvania, that had licenses to produce medicinal whisky.
His daughter, Louise, married Sidney Frank, who well after her death in 1973, became a billionaire creating the vodka Grey Goose and through guerilla marketing of the German cordial, Jägermeister.
Rosenstiel was a friend of attorney Roy Cohn, and together they formed the organization American Jewish League Against Communism.
In 1980, it was purchased by the paper magnate Peter Brant and developed into 95 10-acre sites, sold to celebrities, including Vince McMahon and Ron Howard.
