Gustavus Franklin Swift, Sr. (June 24, 1839 – March 29, 1903) was an American business executive. He founded a meat-packing empire in the Midwest during the late 19th century, over which he presided until his death. He is credited with the development of the first practical ice-cooled railroad car, which allowed his company to ship dressed meats to all parts of the country and abroad, ushering in the "era of cheap beef." Swift pioneered the use of animal by-products for the manufacture of soap, glue, fertilizer, various types of sundries, and even medical products.
