George Henry Hammond, a pioneer in the use of refrigerated railcars for the transport of fresh meat, first used this method with his small packing company in Detroit, Michigan. In 1868, Hammond received a patent for a refrigerator car design. In the early 1870s, he built a new plant in Northern Indiana along the tracks of the Michigan Central Railroad. By 1873, the George H. Hammond Co. was selling $1 million worth of meat a year; by 1875, sales were nearly $2 million. The company's large packing house in Hammond, Indiana—the town had taken the name of its most powerful resident—rivaled those located at the Union Stock Yard in Chicago. By the middle of the 1880s, when it built a new plant in Omaha, Nebraska, Hammond was slaughtering over 100,000 cattle a year and owned a fleet of 800 refrigerator cars. After Hammond died in 1886, the company became less important and no lon ger challenged the giant Chicago packers, who acquired Hammond at the turn of the century and merged it into their National Packing Co.
