Barnett "Barney" P. Ruditsky (December 25, 1898 – October 18, 1962) was a British-born American police officer and private detective. During his 20-year career on the force Ruditsky was among the NYPD's prominent "celebrity detectives" of the 1920s and 1930s. Ruditsky was associated with many criminal cases during this period, most notably, ending with the break-up of Murder Incorporated in 1940. Years later, he was called to testify before the Kefauver hearings due to his knowledge of the criminal underworld in Southern California and Las Vegas.
