Edison 2nd Studio in Manhattan
Located in Manhattan, this was the location of Edison's 2nd studio. His original studio was known as "Black Mariah" and was in West Orange, New Jersey. Being very tiny, Edison need more space and built this rooftop studio in 1901 and used it until he moved into his Bronx location ion 1907.
Edison played no part in the actual movie making at this studio beyond being the owner and namesake.
Today this location is part of a larger parking garage.
