Input: Question: Where was the Organ Company located? Passage:Cyrus Curtis remains #20 on the list of the richest Americans ever. He was known for his philanthropy to hospitals, museums, universities, and schools. He donated $2 million to the Franklin Institute, for example; $1.25 million to the Drexel Institute of Technology for the construction of Curtis Hall; and $1 million to the University of Pennsylvania. He also purchased a pipe organ manufactured by the Austin Organ Company that had been displayed at the Philadelphia Sesquicentennial Exposition of 1926 and donated it to the University of Pennsylvania. It was incorporated into Irvine Auditorium when the building was constructed and is known to this day as the Curtis Organ, one of the largest pipe organs in the world. (The largest is said to reside in Philadelphia's John Wanamaker Building, only twenty blocks east of Irvine Auditorium.) Curtis donated pipe organs to many institutions in Philadelphia and on the day of his funeral, all of those organs were played in his honor.
