While one New York tree gets all the glory, we thought we put together a collection of some other archival Christmas Trees.

In the 1920s, the growing obsolescence, squalid conditions, and rising vacancies in old-law tenements near booming business district provoked developers to dream of lucrative, high-density private construction. Businessman Fred French believed slum clearance was the key to making central city life appealing to the middle-class. Successful redevelopment – what he called “scientific rebuilding” – would require wholesale demolition to change the entire atmosphere of a neighborhood so it could compete with suburban life. Underwritten by an investment plan that sold small-denomination stocks that promised solid returns to investors, French quietly assembled hundreds of tenement properties in Midtown’s east side for his Tudor City project. Clearing for the large hilly site began construction in 1926, and French quickly constructed twelve towers ranging from 10 to 32 stories. The high land coverage and population density were mitigated by the ample open space in adjacent private parks and the quality of the heavily ornamented neo-Tudor buildings. French marketed Tudor City as an amenity-rich alternative for white-collar workers who wanted to “walk to work” rather than endure hours of rail or subway commuting. Designed for the “average salary earner” and his family, the small but luxuriously finished units were complemented by common facilities and overseen by careful community controls.

Three examples of very dense high-rise housing developments suggest how the private market might have rebuilt parts of Manhattan for the middle class if the real estate boom of the late 1920s had not ended in the Great Depression. Two were created by the visionary developer Fred French: Tudor City (1927), a 14.5-acre enclave of a dozen towers on E. 42nd Street, and Knickerbocker Village (1934) on the Lower East side, which replaced some of the district’s oldest tenements with modern, but extremely dense, multifamily housing. The other, London Terrace (1930), packed 1,665 units into an avenue-long apartment block in Chelsea. The density of these middle-class developments averaged 463, 800, and 931 persons per acre, respectively. This story is adapted from an exhibition at the Skycraper Museum.
