The Durst Organization founded in 1915 by Joseph Durst, is the owner, manager, and builder of 13 million square feet of premiere Manhattan office towers and 1,950 residential units with 2,400 under construction. The Durst Organization is recognized as a world leader in the development of high-performance and environmentally advanced commercial and residential buildings.  

Thanks to the advocacy of Dr. Nan A. Rothschild, a renowned urban archaeologist and academic in New York City and a member of the Durst family, The Durst Organization donated the climate controlled space for use as the city’s Archaeological Repository.   

The Durst Organization also supports the Seymour B. Durst Old York Library collection at the Avery Architectural & Fine Arts Library at Columbia University.  Similar to the Rothschild Research Center, Old York consists of more than 40,000 objects that were collected by Mr. Durst throughout his lifetime including historic photographs, maps, pamphlets, postcards, books, and New York City memorabilia from the 18th century to the 1980s.
