It has three buildings: the Tower (1906-09), the North Building (1929-50) and the South Building (1953-60).","why_significant":"The nomination argues the complex is nationally significant in industry, commerce and architecture as the headquarters of one of the nation's most important 20th-century corporations. It shows the company's rise as a leading insurer, a major private investor and a model of corporate design and employee welfare. The buildings span about 60 years of American architectural styles.","narrative":"Occupying two square blocks beside Madison Square Park in Manhattan, this insurance company headquarters grew over decades into a three-building complex. The 50-story Tower, built 1906-09 to designs by Pierre and Michel LeBrun, was briefly the tallest building in the world and carries four large clock dials. The 31-story North Building, designed by D. Everett Waid and Harvey Wiley Corbett and completed in three phases between 1929 and 1950, is a stepped limestone mass with monumental arched corner loggias and a three-story lobby. The 14-story South Building of 1953-60 is a later International style addition and is non-contributing. The complex was recognized for its role in American big business and corporate imagery. It also reflects the company's attention to employee welfare, with dining rooms, murals, gymnasiums and early full air conditioning. Its buildings illustrate Renaissance Revival, Art Deco and International style design.","period_of_significance":"1906-1950","architect_builder":"LeBrun, Pierre and Michel; Waid, D.
