Gerhard Anton Eickhoff (September 11, 1827 – November 5, 1901) was a German-American journalist, editor, author, lawyer, Congressman from New York, United States Treasury auditor, and New York City Fire Commissioner.
He was born in the rural hamlet Kaldewei, part of the village of Benninghausen, Prussia, today suburbanized into Lippstadt, Northrhine, Westphalia, Germany. His parents Caspar Eickhoff (1803–1867) and Maria Catharina Trockel (1803–1863) and their forefathers were peasants in the hamlet Kaldewei, born in serfdom to the Cistercian Cloister of Benninghausen (founded in 1240, secularized in 1804), but ultimately released from serfdom by the Grand Duke in 1809.
After his school education he started to work as a teacher in Lippstadt and publicized radical writings in pre-revolutionary Prussia until 1847.
