Ralph Lamb

Sheriff Ralph Lamb became one of the most recognizable figures in twentieth-century Las Vegas: a Nevada rancher policing a city increasingly shaped by casinos, organized crime and rapid growth. Known as the “Cowboy Sheriff,” he led Clark County’s law enforcement from 1961 to 1979 and became the first sheriff of the merged Las Vegas Metropolitan Police Department.

Born in Alamo in 1927, Lamb grew up in a large ranching family and served in the military during World War II. He later joined the Clark County sheriff’s department, rose to chief of detectives and spent a period running a private detective agency. An unsuccessful election campaign in 1958 did not end his ambitions. He was appointed sheriff in 1961 and won election to a full term the following year, beginning a long tenure during the Strip’s expansion.

Lamb’s reputation rested partly on his willingness to confront powerful men directly. His encounter with Chicago mob figure Johnny Rosselli became a defining story: Lamb demanded that Rosselli comply with the requirement for convicted felons to register with the authorities. Accounts emphasize the physical humiliation that followed. The episode has been retold in different forms, and its colorful details should be read alongside the broader record of Lamb’s relationship with casino operators and organized crime. His career was more complicated than a lone lawman simply driving the Mob out of town.

He also helped modernize policing. His department adopted improved fingerprinting, computers and a SWAT team. In 1973, the city police and county sheriff’s department combined to form Metro, with Lamb remaining sheriff. That institutional change mattered in a valley where the city boundary and the Strip’s location in unincorporated Clark County divided responsibilities. Lamb’s rural image could obscure his role in building a larger, more modern police organization.

His tenure also drew criticism over rough policing and close relationships with influential local figures. Federal tax-evasion charges in 1977 included questions about money borrowed from casino owner Benny Binion; Lamb was acquitted. He lost the 1978 election to John McCarthy and left office in 1979. Lamb died in Las Vegas in 2015, aged 88. The television drama Vegas borrowed from his life, but the historical figure is best understood through both sides of his legacy: the forceful personality of the Cowboy Sheriff and the lasting institution he helped establish.
