major U.S. manufacturer of processed foods, which are distributed throughout the world. The company's “57 Varieties” slogan was devised in 1896; today the company markets several hundred products. Its headquarters are in Pittsburgh, Pennsylvania.

The company was founded in Sharpsburg, Pennsylvania, in 1869 by Henry John Heinz (Heinz, Henry John) (1844–1919), who was later to become nationally known as the “Pickle King.” Heinz had become interested in selling food when he was a child; by age 16, he had several employees working to cultivate the hotbeds and gardens he had built and to deliver his produce to Pittsburgh grocers. His first company, a partnership with two other men, was formed to prepare and market horseradish. Although the company did not survive the business panic in 1875, Heinz reorganized it in 1876 and built it into a major national company by the end of the century. By 1905 it had become the H.J. Heinz Company, the largest producer of pickles, vinegar, and ketchup (catsup) in the United States. By 1919 the company had more than 6,000 employees and 25 factories. Heinz was an astute marketer of his products as well, and he set up a massive electric sign in New York City (1900) to advertise his firm's relishes, condiments, and pickles (see advertising). Heinz was a progressive employer for his time and was one of the few food processors to support a federal Pure Food Act. The corporation was headed by members of the Heinz family until 1969.

In addition to standard products such as ketchup, vinegar, and pickles, Heinz also markets frozen foods, sauces, and pasta under labels such as Ore Ida and Classico. Heinz has processing plants in several countries, and roughly half of the company's sales come from outside the United States.
