In 1961, after he graduated from law school, he went to work for the family company, the
Marmon Group. His elder brother
Jay Pritzker assigned him the task of managing the
Hyatt Hotel chain. Donald moved to
Atherton, California, and went about developing the chain and soon became Hyatt's president. In 1967, the Pritzkers bought a newly built hotel in downtown Atlanta out of bankruptcy which had an unusual design consisting of a 21-story atrium lobby with external glass elevators, fountains, and caged tropical birds. Donald renamed it the
Hyatt Regency Atlanta; it became an instant success and served as the architectural model for all future Hyatt hotels. Donald was credited with "setting the tone for the culture and philosophy at Hyatt" and presided over its growth from a six hotel chain to the 5th largest hotel chain in the world at the time of his death. ==Personal life==
