Famous people in history: Henry J. Heinz

Henry J. Heinz created a condiment synonymous with American cuisine and a company that pioneered benevolent social benefits for its employees. The son of a German immigrant, Heinz relaunched his fledgling business with the creation of Heinz ketchup in 1875 after his horseradish venture failed following the Panic of 1875.

Heinz coined the “57 varieties” slogan that appears on every bottle of Heinz ketchup, a claim which advertised the large number of products Heinz produced. Heinz was born, lived, ran his business, raised his family, and died in Pittsburgh, Pennsylvania.
