Lewis Solon Rosenstiel (July 21, 1891 – January 21, 1976) was the founder of Schenley Industries, an American liquor company, and a philanthropist. The Lewis S. Rosenstiel Award is named after him; the Rosenstiel School of Marine and Atmospheric Science is named after him and his wife.
Rosenstiel was born in Cincinnati, Ohio to Solon and Elizabeth Johnson Rosenstiel. He attended University School and Franklin Prep. He then went to work at his uncle's business, Susquemac Distilling Company in Milton, Kentucky. Rosenstiel organized Schenley Products Company in the 1920s. The company bought numerous distillers, including one in Schenley, Pennsylvania, that had licenses to produce medicinal whisky. In 1933, when Prohibition ended, Schenley Distillers Company was formed as a publicly owned company. (The name was changed to Schenley Industries in 1949.) Schenley became one of the largest liquor companies in the United States. It was one of the "Big Four", which dominated liquor sales, and included Seagram, National Distillers and Hiram Walker. Rosenstiel retired from Schenley in 1968 and it was acquired by financier Meshulam Riklis. The company was sold to Guinness in 1987.
Rosenstiel was a friend of attorney Roy Cohn, and together they formed the organization American Jewish League Against Communism. Rosenstiel was also friends with Federal Bureau of Investigation director J. Edgar Hoover, and was the primary contributor to the J. Edgar Hoover Foundation.
Rosenstiel was married five times: to Dorothy Heller, Lenore Cohn, Louise Rosenstiel, Susan Kaufman and Blanka Wdowiak. His daughter, Louise, married Sidney Frank (who well after her death in 1973 became a billionaire promoting American sales of Jägermeister and Grey Goose.
