school under the Columbia umbrella. After Columbia outgrew its space on Wall Street, it relocated to what is now Midtown Manhattan in 1857. Then President Barnard and the Trustees of the University, with the urging of Professor Thomas Egleston and General Vinton, approved the School of Mines in 1863. The intention was to establish a School of Mines and Metallurgy with a three-year program open to professionally motivated students with or without prior undergraduate training. It was officially founded in 1864 under the leadership of its first dean, Columbia professor Charles F. Chandler, and specialized in mining and mineralogical engineering. An example of work from a student at the School of Mines was William Barclay Parsons, Class of 1882. He was an engineer on the Chinese railway and the Cape Cod and Panama Canals. Most importantly he worked for New York, as a chief engineer of the city's first subway system, the Interborough Rapid Transit Company. Opened in 1904, the subway's electric cars took passengers from City Hall to Brooklyn, the Bronx, and the newly renamed and relocated Columbia University in Morningside Heights, its present location on the Upper West Side of Manhattan. Renaming to the School of Mines In 1896, the school was renamed to the "School of Mines, Engineering and Chemistry". During this time, the University was offering more than the previous name had implied, thus the change of name. The faculty during this time included Michael I. Pupin, after whom Pupin Hall is named. Pupin himself was a graduate of the Class of 1883 and the inventor of the "Pupin coil", a device that extended the range of long-distance telephones. Students of his included Irving Langmuir, Nobel laureate in Chemistry (1932), inventor of the gas-filled tungsten lamp and a contributor to the development of the radio vacuum tube. Another student to work with Pupin was Edwin Howard Armstrong, inventor of FM radio. After graduating in 1913 Armstrong was stationed in France during World War I. There he developed the superheterodyne receiver to detect the frequency of enemy aircraft ignition systems. During this period, Columbia was also home to the "Father of Biomedical Engineering" Elmer L. Gaden. Recent and future developments The university continued to evolve and expand as the United States became a major political power during the 20th century. In 1926, the newly renamed School of Engineering prepared students for the nuclear age. Graduating with a
