Charles Henry Parkhurst (17 April 1842 – September 8, 1933) was an American clergyman and social reformer, born in Framingham, Massachusetts. Although scholarly and reserved, he preached two sermons in 1892 in which he attacked the political corruption of New York City government. Backed by the evidence he collected, his statements led to both the exposure of Tammany Hall and to subsequent social and political reforms.
After further studies in Leipzig in 1872-1873, he was ordained as a Presbyterian minister. He was pastor of a congregational church at Lenox, Massachusetts, from 1874 until 1880, when he was called to the Madison Square Presbyterian church, New York City (1880–1918).
On February 14, 1892, he challenged Tammany Hall from the pulpit. Pointing to the hall’s political influence and their connection with the police, he noted that men fed upon the city while pretending to protect it saying,
"While we fight iniquity, they shield and patronize it; while we try to convert criminals, they manufacture them..."
When the municipal grand jury asked him for hard evidence, Parkhurst personally hired a private detective and, with his friend John Erving, went to the streets in disguise to collect proof of the corruption. From the pulpit on March 13, 1892, he preached a sermon backed with documentation and affidavits. Parkhurst’s campaign led to the appointment of the Lexow Committee to investigate conditions, and to the election of a reform mayor in 1894. Although Tammany Hall did publicly clean house, it remained influential on the both the political front and in organized crime until the 1950's.
His first wife, Ellen Bodman, died on May 28, 1921. He married Eleanor Marx on April 18, 1927 in Los Angeles. He died on September 8, 1933 by sleepwalking and walking off the porch roof in his Ventnor, New Jersey home.
