Robert Loud (not to be confused with Loud Brothers or Thomas Loud of the early 19th Century) was a prominent music dealer and retailer in Buffalo, NY during the early 20th Century. Pianos sold under the 'Robert Loud' brand name were manufactured by the prominent W. P. Haines Piano Company of New York City. The W. P. Haines factory was capable of high volume manufacturing, and they actually manufactured pianos to the specifications of several other firms during the early 20th Century. In addition to pianos sold under the 'Robert Loud' and 'W. P. Haines' brand names, the firm built instruments for The Bradbury Piano Company and the Webster Piano Company. After the Great Depression, the W. P. Haines was absorbed into the large Winter Piano Company of New York. Winter continued building pianos under the W. P. Haines brand name until about 1950. The Robert Loud brand name was discontinued during the Great Depression.
