Siegel, Isaac, 1880-1947

Isaac Siegel (April 12, 1880 – June 29, 1947) was an American lawyer, jurist, and politician. He notably served as the U.S. Representative from New York's 20th congressional district from 1915 to 1923.

Born in New York City, he attended the public schools before graduating from New York University School of Law in 1901 and being admitted to the bar on May 26, 1902. Siegel commenced practice in New York City thereafter and was appointed special deputy attorney general for the prosecution of election frauds in 1909 and 1910. He was elected as a Republican to the Sixty-fourth and to the three succeeding United States Congresses (March 4, 1915 – March 3, 1923) from New York's 20th congressional district. While in Congress, he was chairman of the Committee on the Census (Sixty-sixth and Sixty-seventh Congresses). Siegel was not a candidate for renomination in 1922. A 1924 bid for re-election to the 20th district seat was unsuccessful.

During the First World War, Siegel was a member of the overseas commission which visited France and Italy during July and August 1918. He was also delegate to the Republican National Conventions in 1916, 1920, 1924, and 1936. An unsuccessful candidate for the New York City Council in 1937, Siegel was appointed as a magistrate of New York City on July 4, 1939, serving to September 14, 1940, when he was appointed justice of the domestic relations court of New York City. He served as justice of the domestic relations court until his death from an accidental fall from a window in his New York City apartment.
