The Oster appliance company was launched in 1924 with the introduction of a hair clipper developed by a man named John Oster. Oster purchased the Stevens Electric Co. in 1946 and diversified from barber equipment into a variety of small home appliances, such as blenders and toasters. The Sunbeam Corp. acquired the Oster Manufacturing Co. in 1960 and continues to produce small home appliances under the Oster name. Among Oster brand appliances are microwaves designed to be simple to operate.
