accessed by a set of three "high-speed" elevators in the northern portion of the lobby. There was ventilation equipment on the sixth floor. The seventh through fourteenth floors included offices, as well as rooms for each of the Curb Exchange's committees. There was a fully functional hospital for Curb Exchange employees on the ninth floor. The Board of Governors was housed on the thirteenth floor in a room measuring . History New York's stock trading activity historically took place in outdoor spaces until 1792, when a predecessor to the New York Stock Exchange (NYSE) was founded, and some trading moved into their building. Trading continued to take place "on the curb" outside the New York Stock Exchange Building. The outside traders benefited from the NYSE's refusal to allow trade in some types of securities, and became a leading marketplace for non-listed securities. This market had no fixed location, moving around as traffic and other conditions dictated. Starting in the 1880s, Emanuel S. Mendels and Carl H. Pforzheimer attempted to standardize the loosely organized curb market of curbstone brokers on Broad Street. The New York Curb Market Agency was established in 1908 to codify trading practices. Three years later, the curbstone brokers had come to be known as the New York Curb Market, with a formal constitution and brokerage and listing standards. The Curb Market had offices in the Broad Exchange Building at Broad Street and Exchange Place, though trading remained outdoors. New building By the 1910s, the Curb was handling an increasing volume of shares, and in 1915, its president Edward R. McCormick suggested moving the market indoors to increase investors' trust in the market. Though Mendels had suggested moving the Curb indoors as early as the 1890s, McCormick's proposal was seriously considered as a way to provide a weatherproof location for brokers as well as to remove "unethical bucketeers" from the exchange. In June 1919, the Curb's members formed the Curb Market Realty Association in an attempt to more strictly regulate the market. Later the same month, the Curb's members approved a set of rules that would allow the building to be erected, and limited its future membership to 500 members. The following month, there was a proposal to merge the Curb and the NYSE, a plan that was dropped in November 1919. The Curb Market purchased a L-shaped plot between Greenwich Street and Trinity Place in December 1919
