Recipe Booklet, "Jell-O Ice Cream Powder," circa 1910

In 1899, Orator F. Woodward acquired the rights to Jell-O from Pearle Wait, who had invented Jell-O when he added fruit flavoring and sugar to powdered gelatin in 1897. Woodward used recipe booklets to gather interest, which proved to be an invaluable marketing strategy. Additional Jell-O products included Jell-O Ice Cream Powder, in which homemakers could add milk and freeze it for a frozen treat.
