Newspaper advertisement from Svenska Amerika Posten, January 25, 1933. Clever Elsie is being praised for her preparation of Ry-Krisp, which is to heat buttered crackers and then let them cool.
In 1904, immigrant baker Arvid Peterson gave a Swedish-styled cracker a modern American name and introduced the country to Ry-Krisp. For decades, Minneapolis was the one and only location where the product was made.
