The American Institute of Architects was founded in Lower Manhattan by 29 architects in 1857 to “promote the scientific and practical perfection of its members” and “elevate the standing of the profession.” Until this time, anyone who wished to call themselves an architect, including masons, carpenters, bricklayers, and other members of the building trade, could do so. With over 95,000 members and 200+ chapters, AIA is the largest and most influential network of architects and design professionals in the world. AIANY is the country’s largest chapter and in 2011 it launched Archtober—NYC’s annual, month-long architecture festival. We will honor the AIA National Presidents with a two-part event beginning, with an afternoon walking tour of some of the most distinguished buildings designed by them, that have shaped Lower Manhattan.
