Clarence Lexow (September 16, 1852 – December 31, 1910) was a member of the New York Senate from 1894 to 1898.
He was born on September 16, 1852, in Brooklyn, New York City. His father was Rudolph Lexow (1823-1909) who was born in Germany. His mother was born in England and had died prior to 1880. His siblings include: Charles K. Lexow (1850–1928) who was a lawyer in 1880; Allen Lexow (1855-?) who was a banker in 1880; and Rudolf Grant Lexow (1865-?).
He studied abroad and at the Columbia Law School, where he graduated in 1872. He was admitted to the bar and established his practice in New York City, where he had many German-American clients. In 1880 Clarence was living in Clarkstown, Rockland County, New York with his parents, and he was already a lawyer. Rudolph Lexow, his father was working as an editor. Clarence and Charles also appear as living in Manhattan in the Benedict Building at 79 Washington Place in New York City.
In 1882, he became a resident of Nyack and was active in the Republican Party there. In 1890 he was an unsuccessful nominee for Congress. Though Lexow was unsuccessful, the majority for the Democratic victor was lower than had been usual.
He was a member of the New York State Senate from 1894 to 1898, sitting in the 117th, 118th (both 16th D.), 119th, 120th and 121st New York State Legislatures (all three 23rd D.). Here he at once took a leadership role, and was chairman of the committee on internal affairs and introduced the bi-partisan police bill calling for an investigation of the New York City Police. This led to the appointment, in 1894, of the Lexow Committee, of which he was head. The committee documented how Tammany Hall leaders and the police extorted bribes from operators of gambling and prostitution houses. He was a Senator from the 16th District from 1894 to 1895; and the 23rd District from 1896 to 1898. Lexow was also the introducer of the bill creating the city of Greater New York, was chairman of the joint legislative committee for the investigation of trusts and unlawful combinations, of the committee on primary elections reform, and of the judiciary committee.
