Gus Greenbaum

Gus Greenbaum was a casino operator whose career connected the Flamingo and Riviera with organized crime's expansion into Las Vegas. He helped manage the Flamingo after Benjamin “Bugsy” Siegel's death and later took charge of the financially troubled Riviera. His success as an operator coexisted with the violence surrounding that business world.

Greenbaum belonged to the network of gambling figures who invested in Nevada when legal casinos offered opportunities unavailable in most other states. Alongside Siegel, Meyer Lansky and Moe Sedway, he participated in the 1945 purchase of the El Cortez downtown. At the Flamingo, Greenbaum and Sedway became central management figures. Their work forms an important part of the resort's history after Siegel, whose celebrity often overshadows the people who kept the business operating. The Flamingo's subsequent success encouraged further resort construction and helped make the Strip attractive to investors from different cities and criminal organizations.

The Riviera opened in 1955 with a nine-story tower but soon faced serious financial difficulties. The Chicago Outfit placed Greenbaum in charge of its recovery. He brought experienced associates into the operation and helped stabilize the property. This was a period when casino management, outside financing and hidden criminal interests could be closely intertwined. Public authorities were paying attention: when Senator Estes Kefauver's committee visited Las Vegas in November 1950, Greenbaum had been subpoenaed, although he was not ultimately called into the courtroom. Sedway did testify. The hearing illustrated the widening national scrutiny of the industry in which both men worked.

Greenbaum and his wife, Bess, were found murdered at their Phoenix home on December 3, 1958. No one was prosecuted for the killings, and explanations of who ordered them remain theories rather than established verdicts. Bess's death is also a reminder that the violence of organized crime extended beyond the men who ran its businesses. For visitors, Greenbaum's history brings together three distinct places: the downtown El Cortez, the Flamingo on the Strip and the vanished Riviera farther north. They reveal a working casino executive whose influence was substantial even when his name was less visible than the hotel's entertainers or its most famous investors. His story also shows why successful resort development cannot be separated from the sources of money and power behind it.
