Ronald Kray (24 October 1933 – 17 March 1995) and Reginald Kray (24 October 1933 – 1 October 2000) were identical twin brothers and gangsters, who were the foremost perpetrators of organised crime in the East End of London, England, from the late 1950s to 1967. With their gang, known as the Firm, the Kray twins were involved in murder, armed robbery, arson, protection rackets, gambling, and assaults. In the 1960s, as West End nightclub owners, the Kray twins mixed with politicians and prominent entertainers such as Diana Dors, Frank Sinatra and Judy Garland. They became celebrities themselves, were photographed by David Bailey and interviewed on television. The Kray twins were arrested on 8 May 1968 and convicted in 1969 as a result of the efforts of detectives led by Detective Superintendent Leonard "Nipper" Read. Each was sentenced to life imprisonment. Ronnie was committed to Broadmoor Hospital in 1979 and remained there until his death on 17 March 1995 from a heart attack; Reggie was released from prison on compassionate grounds in August 2000, five weeks before he died of bladder cancer.
