Richard S. Newcombe (1880-1930) had a long and illustrious career in public service, including as the Queens County District Attorney in the 1920s, where he prosecuted several notable cases, including a scandalous murder trial that was dramatized as a famous Hollywood film.

Newcombe was born in Manhattan on in 1880. His father, also named Richard, was a law partner to Albert Cardozo, whose son, Benjamin, also became a lawyer and then a judge who served on the New York Court of Appeals and as an Associate Justice of the U.S. Supreme Court. After attending public school, Newcombe went to Phillips Andover Academy, then to New York Law School, passing the bar in 1904.

After working for a law firm and launching an unsuccessful bid for Justice of the Supreme Court, Newcombe began his career in public service when the corrupt Queens Borough President Maurice Connolly appointed him as Queens Public Works Commissioner. The two clashed and he didn't last long in the position, next running for Queens District Attorney in 1923, defeating the incumbent, and then winning reelection three years later by a substantial margin. One of the cases he pursued was a $16 million sewer contract scandal in Jamaica, which ultimately caused Connolly to resign.

The most famous case he prosecuted, however, came in 1927. On March 20th of that year, Ruth Snyder and her lover, Henry Judd Gray, murdered Snyder’s husband, Albert, in the couple’s Queens Village home, staging it to appear as a robbery. Their sloppy alibi was further diminished by the discovery that Snyder and Gray had recently taken out a double indemnity insurance policy together, which, if Albert died accidentally, would pay twice as much.

The trial was a sensation from the start, with a media circus that resulted in unprecedented news coverage, but it culminated in even more sensationalism. After being found guilty and sentenced to death by electrocution, a Daily News reporter snuck a camera into Snyder's execution room. The photograph that captured the moment of her electrocution was on the front page the next day, and the paper sold out in 15 minutes.

The murder gained more notoriety following the release of James Cain’s 1943 novella Double Indemnity and its 1944 classic film adaptation, all based on this true-life story.

Newcombe did not live to see these dramatizations, however. He was elected as Surrogate of Queens County in 1929, and May 7, 1930, was Newcombe's first day as a judge. He had a packed schedule, presiding over three jury trials and overseeing the installment of another jury. In addition, the city was in the middle of a heat wave. At the end of this exhausting workday, Newcombe, along with his wife, Rosena Reis Newcombe, and accompanied by his secretary, visited a heart specialist. He and his wife then joined his brother-in-law for dinner before returning home. Just after 10pm, Rosena contacted the secretary to notify him that Newcombe had died, having collapsed as he was dressing for bed.

Though it was a modest ceremony, more than a thousand people gathered for his funeral, held at his home at 75 Greenway Terrace in Forest Hills. Newcombe had been a leader with the Boy Scouts for some time, and the only official ceremonial aspect to the funeral was led by them. Twenty Eagle Scouts served as a guard of honor at his home, and they played taps as Newcombe's casket was lowered in Woodlawn Cemetery.

Newcombe had been a leader across many areas. In addition to serving as president of the Boy Scouts Sustaining Association of Queens, and having inspired the naming of Camp Newcombe in Wading River, Long Island, he had been a director of Flushing Bank, helped to organize the Boulevard National Bank in Forest Hills, and served on the board of the American Trust Company.

By January 1937, friends and colleagues of Newcombe set out to petition the Board of Aldermen and the Transit Commission to rename this triangle and the nearby Kew Gardens subway station, which had just opened a week earlier, in his honor. On November 18, 1939, around 100 of those supporters gathered to unveil a granite block with a bronze plaque to designate the area as Newcombe Square.
