The life in photos of Tucson developer and philanthropist Donald Diamond, who owned Diamond Ventures.

Diamond was born in New York and first became enamored with Tucson when he attended the Brandes School, a boarding school near where Park Place now stands.

He returned to the East Coast for high school in Washington, D.C., served in the U.S. Army Infantry during World War II and attended the University of Arizona from 1947 to 1949. He met his wife, Joan, at UA.

He retired as a commodities broker in 1965 and moved his family to Tucson. He began to dabble in real estate. Over the next 50 years Diamond became a large, if not the largest, private land owner in Pima County and one of the most influential private-sector businesspeople and deal-makers in Arizona. – Ann Brown
