George Henry Griebel (13 August 1846 – March 1933) was a prominent Berlin-born and trained architect who resided in New York City. He designed numerous public and private buildings, many of which are still standing in New York City, Philadelphia, and Washington DC. However, because at the time an architect did not receive credit for his work unless he owned his own firm, Griebel is largely uncredited for buildings such as the Dakota Building and other luxury apartment buildings in New York City, a staircase in the Library of Congress, the design for Grant's Row, planned as the home of embassies in Washington, DC, and many other buildings. The original architectural drawings of the Dakota building and the Singer Building are in the private collection of the Griebel family.
