In 1908 Herbert Johnson, an engineer for the Hobart Manufacturing Company, invents an electric standing mixer. His inspiration came from observing a baker mixing bread dough with a metal spoon; soon he was toying with a mechanical counterpart. By 1915, his 80-quart mixer was standard equipment for most large bakeries. In 1919 Hobart introduced the KitchenAid Food Preparer (stand mixer) for the home. A mixer is a kitchen appliance intended for mixing, folding, beating, and whipping food ingredients. Mixers come in two major variations, hand mixers and stand mixers.
