The former Mount Prospect Laboratory in Prospect Heights, Brooklyn, built in 1938, architect: Aymur Embury II[1]. The lab was designed to fit into the neighborhood; it looked like a residence, not an official city structure. It would serve as the city's water testing laboratory until it was replaced by the current building in 1938. That unique Moderne style building was designed by the prominent architect Aymar Embury II for the Department of Water Supply, Gas & Electric of the City of New York. Embury is most famous for his collaboration with Robert Moses during the Great Depression years, creating recreation centers, city pools and other park buildings throughout the city. ... The new Mount Prospect Laboratory stayed in operation, testing water from all across the systems, until the 1960s. It was then transferred over to the Department of Education, which still has the building. Today, it is the only remaining structure in the neighborhood that references the great public works complex that was the Mount Prospect Reservoir.[1]
