Mary Agnes Sullivan built a remarkable 35-year career as a pioneering policewoman in New York City. She became the first woman homicide detective in the New York City Police Department, breaking down barriers and setting new standards for women in law enforcement. Her achievements were numerous, including being the first woman to make lieutenant, the second woman to achieve the rank of first-grade detective, and the first woman inducted into the NYPD Honor Legion. Sullivan’s dedication and contributions to the force were recognized when she was appointed as the director of the Bureau of Policewomen, a position she held for the last 20 years of her career.

Sullivan’s impact on law enforcement extended beyond her achievements. She inspired other remarkable women, such as Mae Foley, to follow in her footsteps. Foley, who joined the New York City Police Department in the early 1920s, also became a trailblazer for women in law enforcement. She broke barriers and fought against gender biases, becoming one of the first women to work as a plainclothes detective in New York City. Like Sullivan’s, Foley’s determination and perseverance inspired countless women to pursue careers in law enforcement.

Despite their significant contributions, Sullivan and Foley faced challenges and resistance during their careers. Both women encountered skepticism and prejudice from male officers, and sometimes even from the very prisoners they sought to protect. However, their unwavering commitment and remarkable achievements opened doors for future generations of women in law enforcement.

Sullivan’s illustrious career and experiences as a New York City police detective during the late 1920s and 1930s were documented in her autobiography, “My Double Life: The Story of a New York Policewoman.” Initially published in 1938, the book sheds light on her journey as a trailblazing woman in law enforcement. Its significance and relevance were evident as the autobiography was re-released in 1983, ensuring that Sullivan’s story continued to inspire future generations.

Mary Agnes Sullivan and Mae Foley, alongside other pioneering women in law enforcement, have left an indelible mark on women’s history in the field. Their determination, courage, and groundbreaking achievements have forever changed the landscape of law enforcement, inspiring countless women to pursue careers in this traditionally male-dominated profession.
