The company's claim to fame today is that it built the world's largest pipe organ: the Boardwalk Hall Auditorium Organ in the Atlantic City Convention Hall, Atlantic City, New Jersey; inaugurated in 1932, it has over 33,000 pipes controlled from a seven-manual console. Unfortunately, the company went bankrupt in the process. The organ still exists but is only partially playable, there is some question as to whether all of it was ever playable at the same time.
