Gustavus Franklin Swift

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.

Swift donated large sums of money to such institutions as the University of Chicago, the Methodist Episcopal Church, and YMCA. He established Northwestern University's "School of Oratory" in memory of his daughter, Annie May Swift, who died while a student there. When he died in 1903, his company was valued at between US$125 million and $135 million, and had a workforce of more than 21,000. "The House of Swift" slaughtered as many as two million cattle, four million hogs, and two million sheep a year. Three years after his death, the value of the company's capital stock topped $250 million. He and his family are interred in a mausoleum in Mount Hope Cemetery in Chicago.
