Andaz is an international company and operator of hotels. The Hyatt Corporation was born upon purchase of the Hyatt House, at Los Angeles International Airport on September 27, 1957. The original owners were entrepreneurs, Hyatt von Dehn and Jack D. Crouch. Von Dehn was eager to get out of the hotel business after a few years, so he sold his share in the hotel to Jay Pritzker. Jay's younger brother Donald Pritzer, under Jack Crouch's mentorship, took over day-to-day operations of the company and acquired motels and hotels. Under Donald's leadership, Hyatt became the fastest growing hotel chain in the United States until his death in 1972.
