Rose M. Singer (1896-1991) was a longtime jail reform activist and an original member of the New York City Board of Correction. She volunteered for the Board for more than three decades, beginning with its inception in 1957. In the early 1950s, she was founder and first president of the Friendly Visitors, a service group that helps women in prison.

Singer was born in Brooklyn to Russian-immigrant parents Samuel Singer, a presser, and Molly (Cluhock) Singer. After graduating from Brooklyn College, she continued her studies at Columbia University, where she earned a master’s degree in child psychology.

In 1956, she received an award for distinguished and exceptional service to New York City from Mayor Robert F. Wagner, Jr., in recognition of 20 years of volunteer work. A year later, Wagner appointed her as one of nine members to the Board of Corrections, a newly formed volunteer citizen watchdog group formed to assist the Department of Corrections with managing and planning and to serve in a monitorial role on behalf of the public. Singer continued to serve on the Board until her death in 1991, when she was the last of the original nine.

Active in civic affairs, Singer fulfilled many roles, serving at various times as chairwoman of the voluntary advisory council to the Department of Correction, chairwoman of the executive committee of the Women's Prison Association, vice chairwoman of the Citizens Union of the City of New York, and trustee of the National Conference of Christians and Jews. At their 50th anniversary celebration in 1977, the National Conference of Christians and Jews named Singer as one of 50 Women of Achievement. On June 20, 1988, a ribbon cutting ceremony was held to dedicate a new $100 million jail for women on Rikers Island as the Rose M. Singer Center in Singer’s honor.

Singer died of heart failure at her home in Manhattan on March 14, 1991. She was survived at the time by three sons (Ronald, Edward, and Martin), seven grandchildren, and two great-grandchildren.
