Who is the founder of the Hyatt hotels?

The original owners of the Hyatt House at LAX (the first to be built just outside an airport) were entrepreneurs, Hyatt von Dehn and Jack Crouch (1950-1992). The Hyatt hotel chain was started by Jay Pritzker (1922-1999) by his purchase in 1957 of that hotel. Crouch left the company in 1965. The Pritzkers are one of Chicago's wealthiest families.
