Built into Boardwalk Hall’s Main Auditorium in Atlantic City between 1929 and 1932, the Boardwalk Hall Auditorium Organ is widely recognized as the world’s largest pipe organ, with 33,112 pipes. Designed by Emerson Lewis Richards and Seibert Losh for the hall’s immense interior, it used unusually high wind pressures and eight hidden chambers to project sound without amplification. Its seven-manual console, 1,235 stoptabs, 64-foot pipe ranks, and extraordinarily powerful Grand Ophicleide and Diaphone-Dulzian made it one of the most ambitious and loudest musical instruments ever created. After decades of damage and neglect, restoration since the 1990s has gradually returned major sections to service.
