7 Up was created by Charles Leiper Grigg, who launched his St. Louis–based company The Howdy Corporation in 1920. Grigg came up with the formula for a lemon-lime soft drink in 1929. The product, originally named Bib-Label Lithiated Lemon-Lime Soda, was launched two weeks before the Wall Street Crash of 1929. It contained lithium citrate, a mood-stabilizing drug, until 1950.
