The Kray twins were English gangsters who were foremost perpetrators of organized crime in London’s East End during the 1950s and ’60s. Ronald, commonly referred to as Ron or Ronnie, most likely suffered from paranoid schizophrenia. With their gang, The Firm, the Krays were involved in armed robberies, arson, protection rackets, assaults, and the murders of Jack “The Hat” McVitie and George Cornell. As West End nightclub owners, they mixed with prominent entertainers including Diana Dors, Frank Sinatra, Judy Garland and with politicians. The Krays were much feared within their milieu, and in the ’60s became celebrities in their own right, even being photographed by David Bailey and interviewed on television.
