Hyatt Hotels Corporation, commonly known as Hyatt, is an American multinational hospitality company headquartered in the Riverside Plaza area of Chicago, Illinois. Hyatt was founded by Jay Pritzker in 1957 when he purchased the Hyatt House motel adjacent to the Los Angeles International Airport. Over the following decade, Jay Pritzker and his brother, Donald Pritzker, grew the company into a North American management and hotel ownership company, which became a public company in 1962. In 1968, Hyatt International was formed and subsequently became a separate public company. Hyatt Corporation and Hyatt International Corporation were taken private by the Pritzker family business interests in 1979 and 1982, respectively. On December 31, 2004, substantially all of the hospitality assets owned by Pritzker family business interests, including Hyatt Corporation and Hyatt International Corporation, were consolidated under a single entity called Global Hyatt Corporation. In 2009, the company went public again and was renamed to its current name, Hyatt Hotels Corporation.
