Heinz was founded by and is named for Henry J. Heinz, who was born in the United States to German immigrants. He began packing foodstuffs on a small scale at Sharpsburg, Pennsylvania, in 1869. There he founded Heinz Noble & Company with a friend, L. Clarence Noble, and began marketing horseradish.
The first product in Heinz and Noble's new Anchor Brand (a name selected for its biblical meaning of hope) was his mother Anna Heinz's recipe for horseradish. The young Heinz manufactured it in the basement of his father's former house.
The company went bankrupt in 1875. The following year Heinz founded another company, F & J Heinz, with his brother John Heinz and a cousin, Frederick Heinz. One of this company's first products was Heinz Tomato Ketchup. The company continued to grow.
In 1888, Heinz bought out his two partners and reorganized the company as the H. J. Heinz Company. Its slogan, "57 varieties", was introduced by Heinz in 1896. Inspired by an advertisement he saw while riding an elevated train in New York City (a shoe store boasting "21 styles").
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. The corporation was headed by members of the Heinz family until 1969.
In 1978 the Heinz Company acquired Weight Watchers International, Inc., a producer of low-calorie meals whose weight-loss program eventually became the largest of its kind in the United States. Soon afterward the company began a period of global expansion that continued through the early 21st century. Heinz acquired food-processing companies and established subsidiaries in China, Africa, central and eastern Europe, and the Pacific Rim.
In 2015 Heinz’s holding company merged with Kraft Foods to form Kraft Heinz Company. Heinz subsequently became a division and brand within the newly formed conglomerate.
