Philosophy Hall
Designated a National Historic Landmark
of New York City on 7/21/2003.

Landmark Description
As a senior at Columbia University’s new Philosophy Hall in 1912, Edwin H. Armstrong worked in the second-floor Hartley Laboratories on his first of several major developments in wireless communication technologies. After graduation the promising young engineer was assigned a small laboratory to continue his work, and eventually became the head of the Hartley Laboratory. Even after a series of inventions made him not only wealthy, but one of the foremost inventors in wireless technology, Armstrong continued to use these second-floor laboratories and office facilities, as well as lecture rooms elsewhere in Philosophy Hall, to advance his work. The last of his major developments was the design of a wide-band frequency modulation (FM) system that achieved unprecedented fidelity and elimination of static. This revolutionary technology was met with resistance from those heavily invested in the well established amplitude modulation (AM) system. Unfortunately, Armstrong’s untimely death in 1954 prevented him from witnessing the eventual widespread dominance of his FM system.

citizens throughout the nation, the National Historic Landmarks
Program draws upon the expertise of National Park Service staff who
guide the nomination process for new Landmarks and provide
