Piano maker and music publisher. Rolfe was a partner with Thomas Culliford making square pianos for Longman & Broderip until the firm became bankrupt in 1796. He continued in business with Culliford but left the business in 1798 to trade alone at 112 Cheapside. His early square pianos are noted for their floral painted nameboard decoration and internal music stand that incorporated a second music desk for accompanying musicians. The firm became William Rolfe and Sons in the early 19th century.
