James W. Pirsson

His father “was a well-known piano-forte manufacturer and musician who helped to found the New York Philharmonic Society. Pirsson received his training from an English architect named Weeler and was engaged in a very active practice before joining with Hubert in 1870. In that year, the two men are listed as the architects for two third-class tenements erected on East 49th Street between First and Second Avenues under the first name Hubert & Pirsson. Their partnership lasted until Pirsson's death in 1888. Upon his death, the firm operated under the name Hubert, Pirson & Haddick, until 1893 when Hubert retired.
