Francis Taylor and Guitan B. Dupuy established the firm of “Taylor & Dupuy” in 1859 in New York City.  By 1870 Taylor & Dupuy was producing about 50 pianos and melodeons annually, and they had a reputation for building fine instruments of exceptional quality.  A small and conservative firm, Taylor & Dupuy never built pianos in large numbers and they enjoyed several years of modest success until 1881.

Francis Taylor:  Guitan B. Dupuy withdrew from the firm of “Taylor & Dupuy” in 1881 in order to establish his own firm building pianos under his own name.  In 1882, Francis Taylor admitted his son into partnership and the firm was reorganized as “Taylor & Son” at 8 East 18th Street.  Taylor & Son continued to build pianos and organs until just after 1890.

Guitan B. Dupuy: Guitan B. Dupuy withdrew from the firm of “Taylor & Dupuy” in 1881 n order to establish his own firm building pianos under his own name.  In 1885 Dupuy admitted his son, John S. Dupuy, into the firm and reorganized as “The Dupuy & Son Piano Company” at 42 Clinton Place, New York City.  The Dupuy & Son Piano Company was a short lived partnership and appears to have been out of business before 1887.
