O'Neill, William

William (Michael J.) O’Neill was a long-serving and influential law-enforcement official whose career placed Englewood at the center of New Jersey’s early-20th-century movement toward police professionalization. O’Neill spent approximately 25 years with the Englewood Police Department, including five years as chief from 1924-1929. He gained statewide recognition for his emphasis on training, discipline, and modern police methods. His leadership extended well beyond the city: by the late 1920s he was president of the New Jersey State Association of Police Chiefs and a member of the International Association of Chiefs of Police, signaling his role as a key figure in shaping policing standards across the state. A clear example of O’Neill’s reform-minded approach was his active collaboration with H. Norman Schwarzkopf, then superintendent of the New Jersey State Police. O’Neill invited Schwarzkopf to Englewood to deliver what was reported as the first in a planned series of professional police lectures, urging that all available patrolmen attend. Schwarzkopf’s talk on the “ethics of police work” reflected a shared belief that effective policing required formal instruction, ethical grounding, and continuous education—not merely on-the-job experience. These lectures were intended to function almost as a regional police school, reinforcing Englewood’s reputation as a hub for professional development. O’Neill’s career ended tragically in December 1929, when he died by suicide after being missing for two days. Contemporary accounts noted that he had recently undergone serious surgery, had returned to duty while still in considerable pain, and was described as physically and emotionally strained. His death drew wide attention throughout New Jersey, underscoring both his prominence and the intense pressures faced by senior police officials in an era when occupational stress and mental health were rarely acknowledged. Funeral services were held in Englewood, with interment at Mount Carmel Cemetery in Tenafly, and were attended by police leaders from across the state. He was survived by his widow and two sons. Together, O’Neill’s partnership with figures like Norman Schwarzkopf and his advocacy for ethics-based training illustrate his role in the transition from informal, local policing to a more centralized, professional, and credentialed model in New Jersey—while his death highlights the personal toll such leadership could exact in the early 20th century.
