The Master Institute was founded by Nicholas Roerich in 1921, and for much of its existence was housed in the Master Apartments. The Master Apartments were designed by Harvery Wiley Corbett in 1929 for Roerich and built on the site of the former Horch mansion at 310 Riverside Dr. in New York City. After ligitgation in 1938, Louis and Nettie Horch took ownership of the building. They were also closely associated with the Bloomingdale Neighborhood Conservation Association, a cooperative partnership between the City of New York and private citizens to improve the housing and social conditions of residents of the Bloomingdale neighborhood in New York City.
