KitchenAid is an American home appliance brand owned by Whirlpool Corporation. The company was started in 1919 by The Hobart Manufacturing Company to produce stand mixers; the "H-5" was the first model introduced. The company faced competition as rivals moved into this emerging market, and introduced its trademarked silhouette in the 1930s with the model "K", the work of designer Egmont Arens. The brand's stand mixers have changed little in design since, and attachments from the model "K" onwards are compatible with the modern machines.
