William H. Christopher was a small-scale piano maker during the 1840s and 1850s era. He is first listed as a partner with Wales Grow in the firm of Grow & Christopher in 1847. Their workshop located at 130 Avenue 3, New York City and they were both a retailer and manufacturer of pianos and possibly melodeons. The firm built primarily square grand pianos both under the names of 'William H. Christopher' and 'Grow & Christopher', and their instruments had a reputation of being built with superb craftsmanship. The firm was dissolved in 1857 when William Christopher left the piano industry to pursue other business interests.
