Incorporated on August 24, 1926
Joseph L. Rosefield was the inventor of hydrogenated peanut butter. Before this process was developed, peanut butter would separate and quickly spoil. Mr. Rosefield received a patent for his process in 1923 and three more patents as he improved the process over the next seven years. Under Mr. Rosefield's guidance, his packing company in Alameda became the largest peanut butter manufacturer in the nation with up to 90 employees working three eight hour shifts, seven days per week. The product was sold under the name "Skippy Peanut Butter." Tours of the facility were enjoyed by generations of Alameda school children. The Alameda plant closed in 1974. The Skippy brand continues to be popular today.
