Eidlitz was born in Prague, into a Jewish family; his parents were Abraham and Judith Eidlitz, and he had one brother Markus Eidlitz. He received his early technical training at the Prague Realschule and then continued his education at the Vienna Technical University. He enrolled in its short-lived business school, not its engineering or architecture curricula. Eidlitz emigrated from Vienna to the United States in 1843 and settled in New York. His brother Marc Eidlitz emigrated to New York three years later. ", home of P. T. Barnum, built in 1848 near Bridgeport, Connecticut Eidlitz spent three formative years in the office of Richard Upjohn. He likely participated in his project of constructing Trinity Church at the head of Wall Street, which was under way. He also worked with the architect Cyrus Lazelle Warner, whose office was a few doors from that of Upjohn's. In 1846 Eidlitz formed a partnership with the German immigrant architect Karl Otto Blesch, who had trained in Munich with Friedrich von Gärtner. One of their several joint commissions in New York was for St George's Episcopal Church, still standing on the west side of Stuyvesant Square. Blesch designed the exterior, mixing Gothic and Romanesque styles, and Eidlitz designed the plain interior and the original openwork spires. The Episcopal congregation was so satisfied with the design that they rebuilt the church after a disastrous fire in 1865 following the same design, under Eidlitz' supervision. By that time the design was also influenced by Dr. Stephen Tyng, a new pastor hired for what had become a changing urban congregation, in a neighborhood largely filled with immigrants. J.P. Morgan, still an influential parishioner, helped support many social services programs started by the church. Eidlitz's reputation was marred by his involvement, with H. H. Richardson and Frederick Law Olmsted, in the re-design of the New York State Capitol in Albany. In 1875, Eidlitz, Richardson, and Olmsted proposed changes to the capitol, which was already under construction to designs by Thomas Fuller. In 1876 state officials dismissed Fuller and hired the trio, causing tremendous controversy. Eidlitz designed the capitol's Assembly Chamber and its now dismantled vault. Eidlitz was a founding member of the American Institute of Architects in 1857. In 1859, he joined the Century Association.
Writing on architecture
Eidlitz wrote numerous articles published in such journals as The Crayon in the 1850s and the American Architect and Building News beginning in the 1870s. He published a major book , which proposed an organic theory of architecture that wedded German notions of art and science to American transcendentalist concerns.
Marriage and family
Eidlitz married Harriet Amanda Lazelle Warner in 1845. He had worked with her father Cyrus Lazelle Warner. Her mother was Elizabeth Wadland Adams, who, despite claims she made during her lifetime, was not descended from President John Adams. By means of this marriage Eidlitz helped secure his family's social place in the United States. Episcopal priest Stephen Tyng presided their wedding. They had seven children, but the first died soon after birth. Their eldest son, Cyrus Lazelle Warner Eidlitz, was also an architect, designing the St. George Memorial House and founding the firm Eidlitz & McKenzie, designers of the New York Times Building, One Times Square. Leopold's brother Marc Eidlitz was the founder of a major construction firm, Marc Eidlitz & Son Builders N.Y.C. in New York, which built the St. Regis Hotel and many other projects. Marc converted to Catholicism and kept close ties to the German immigrant community, becoming president of Germania Bank in 1888. Eidlitz has been called America's first Jewish architect. In his early work, as at the Shaaray Tefila synagogue, Eidlitz identified himself as Jewish to clients. Other evidence suggests he later hid his heritage; his marriage was officiated by the Episcopal priest Tyng, and the Eidlitz children were raised as Christian, according to their mother's tradition. Eidlitz presented himself as simply German or Austrian and he Germanicized his parents' given names on American records. One of his daughters, Mari Imogene Eidlitz, was married in a Catholic ceremony in 1887 at St. Anne's Church in New York. in Manhattan, New York City. Eidlitz designed the interior, and supervised its reconstruction in 1865 after a fire.
