Hal Erickson and Robbins Cahill looking at his 5-volume oral history at the University of Nevada, Las Vegas. Typed description provided with image: "Robbine Cahill Oral History Transcript. [April 01, 1979, L-R: Hal Erickson; Robbins Cahill]. State regulation of gaming in Nevada began with Robbins Cahill. As early as 1945 when we became a member of the nevada State Tax Commission, Cahill had been in part responsible for enforcement of the state's first gaming regulations. When Nevada's Gaming Control Board was established in 1955, Cahill became its first chairman. With his encyclopedic memory Robbins Cahill is the most authoritative figure on gaming history in Nevada. His six-volume oral history is the richest and most vivid source of information in Nevada on the development of state gaming regulation."
