Hubert & Pirsson was a New York City architectural firm, founded by Philip Gengembre Hubert (1830 1911) and James W. Pirsson (1833 1888), which was active from c.1870 to 1888. It was later known as Hubert, Pirsson and Company, and Hubert, Pirsson & Haddick from 1888-1898. Active during New York City's "Gilded Age", the firm produced many of the city s finest buildings, including hotels, churches and residences, and were especially noted for their luxury co-operative apartments and residential hotels. The French-born Hubert and the New York City-native Pirsson, who was trained by an English architect, established their partnership around 1870; the former s father was the architect and engineer Charles Antoine Colomb Gengembre, while the latter s father was a well-connected "piano-forte manufacturer and musician who helped to found the New York Philharmonic Society."
