Cyrus Lazelle Warner Eidlitz (July 27, 1853 – October 5, 1921) was an American architect, educated in Germany, best known for designing One Times Square in New York City.
The young Eidlitz was educated in New York, then to Europe in Geneva, Switzerland and following in Stuttgart, (Germany), where he studied architecture at the Polytechnic Institute.
His early Gothic and Romanesque Revival designs, including Dearborn Station in Chicago, Michigan Central Station (1887) in Kalamazoo,[1] and the precursor to the current Buffalo & Erie County Public Library in Lafayette Square, show his father's influence.
Eidlitz & McKenzie was one of the first architecture firms that put architects and engineers on equal footing.
The interior decoration design of the Arnot Memorial Chapel at Trinity Church in Elmira, New York is also attributed to him.
