Planning and construction William Fletcher Weld, who died in 1881, was described as one of the most successful merchant ship owners in the United States. He left a $21 million estate (equivalent to $ million in ), much of which went to his grandchildren William Fletcher Weld Jr., Charles Goddard Weld, Mary Bryant Pratt Sprague, and Isabel Weld Perkins. The Weld estate bought the northwest-corner lot at Broadway and Duane Street from the Hale estate in May 1888 for $350,000. At the time, the lot contained a three-story brick building with a restaurant on the ground floor and offices on the upper floors. Two years later, the estate acquired an interior lot adjacent to that property. Within eleven years, it had become the world's "purely
mutual natural-premium" life insurance company. By the time the building was announced in January 1892, Mutual Reserve had agreed to lease space in the Weld estate's new building for its new headquarters. The lease would run 40 years from June 1, 1894, and was based on a percentage of the construction cost and the $500,000 land value. Mutual Reserve was recorded as having paid $408,297 for the lease, as well as construction and furnishings. Hume filed plans for the Mutual Reserve Building in June 1892, by which it was planned as a 13-story structure. Construction was also held up by strikes at the granite supplier's factory. The building, officially completed in September, ultimately cost $1.2 million in total. The building's contractor Richard Deeves & Son, as well as a bicycle showroom and architects, also took up space in the building. and reorganized as the Mutual Reserve Life Insurance Company in 1902, although further scrutiny led to the company's vice-president and president being indicted in 1906. In the wake of this controversy, the building's private executives' elevator was closed in June 1907. even though the company had just entered
receivership. 305 Broadway had become known as the Langdon Building by 1909, when Hume filed plans for minor building modifications. The building was probably named after John Langdon Brandegee, a
stock broker who was the son of the sole owner at the time, Mary Bryant Pratt Sprague. During the mid-1910s, the ground floor space was taken by the Standard Lunch Company and Emerson Shoe Company. The new owner planned to renovate the building for lawyers' use at a cost of $40,000 to $50,000, and planned to rename the structure as the Lawyers' Building. The purchase was due to the building's proximity to courthouses on
Chambers Street and the lack of available space for lawyers in the
Financial District. and a 1920s hub of the "personal injury underworld". Other tenants during that time included metal supplier Herman J. Heght Inc.; the
Amalgamated Lithographers of America; architecture firm Marcus Contracting Company; architect George F. Hardy; and a temporary location of the Wall Street Synagogue. The building was sold in 1940 to the Downtown Renting Company, and it was refinanced for $300,000. At the time, 305 Broadway was entirely rented, with most of the tenants being lawyers. Five years later, the building was sold to Broaduane Corporation. The Jewish Forum Association, which published a journal called the
Jewish Forum, operated in the building in the 1940s. During the next decade, many agencies of the New York state government started moving in. Through the 1960s, the city government's departments of Real Estate and Relocation also occupied space in 305 Broadway. The building also served as the first permanent headquarters of the
New York City Landmarks Preservation Commission (LPC) from 1967 to 1980. Reade Broadway Associates bought the building two years later. The building officially became a city landmark in 2011. It is one of several remaining life-insurance company headquarters on the southernmost section of Broadway, along with the
