George Samuel Dougherty (April 5, 1865 – July 16, 1931) was an American law enforcement officer, private detective and writer. He was considered one of the leading detectives in the United States, first for the Pinkerton Detective Agency and then as a private investigator. Dougherty was responsible for the capture of many notorious criminals during the late 19th and early 20th centuries. He also introduced the modern-day fingerprinting to the police force. While serving as Second Deputy Police Commissioner and head of the NYPD Detectives Bureau, he is credited for his assistance in solving the 1912 murder of Herman Rosenthal which ultimately resulted in the conviction and execution of the Lenox Avenue Gang and NYPD police detective Lieutenant Charles Becker. Biography Early life and career with the Pinkertons Born to Charles A. Dougherty and Ellen June in Cressona, Pennsylvania on April 5, 1865, George Dougherty worked as a printer before joining the Pinkerton Detective Agency in 1888. Dougherty soon established himself as one of the agency's top men and apprehended countless criminals during his twenty-three years with the Pinkertons. Dougherty eventually took charge of the Pinkerton's branch in New York City and held that position until accepting an offer from Mayor William Jay Gaynor to become Deputy Police Commissioner of the New York City Police Department on May 1, 1911. NYPD & the Rosenthal murder His appointment was seen as an attempt to reorganize the NY Police Department. Succeeding William J. Flynn, Dougherty reported directly to Police Commissioner James C. Cropsey who would later become a Supreme Court Justice. He would have a stormy relationship during his two and a half years with the NYPD however. A strict disciplinarian, he exerted considerable control over his men and was responsible for "shaking up" the bureau on several occasions: he also led raids on a number of illegal gambling establishments, arresting the crime boss Giosue Gallucci, and, in one incident, used axes to force their way in. When Herman Rosenthal was gunned down in front of the Hotel Metropole on July 16, 1912, then District Attorney Charles S. Whitman accused the police department of making little effort to apprehend the gunmen. One of the few exceptions, according to Whitman, was the assistance given by Dougherty who had been personally cooperating with the District Attorney's office and was praised for his honesty. Prior to leaving the police force, Dougherty led a detective squad
