1905—School of Mines building on the Morningside campus is completed. The School expands from the Engineering Building (now known as Mathematics) which had been its primary home since 1897. In 1961, when the School moves to the new Mudd Building and General Studies moves in, the Mines Building is renamed Lewisohn Hall after Adolph Lewisohn, who helped fund the building's construction. Shown in 1908; in the upper right photo it is in the center with Earl Hall to the right.

1912—The Polo Grounds: right field (left) and during the World Series (right). The first version was built in 1876 for playing polo. It was bounded by 110th and 112th Streets and Fifth and Sixth Avenues. The field was used at times by the baseball New York Giants, Yankees, and Mets and by the football New York Giants and Jets. It was best known as the long-time homes of the two Giants teams. The last sporting event was the football game between the New York Jets and the Buffalo Bills on December 14, 1963.
1912—Columbia junior Edwin H. Armstrong invents the regenerative circuit, which greatly strengthens radio signals to make them more audible. (He is shown (upper left) as a student and (lower) during World War I.)
This invention occurs at his home (1032 Warburton Ave., Yonkers). “His sister, Ethel, remembers vividly the night it happened. “Mother and Father were out playing cards with friends and I was fast asleep in bed. All of a sudden Howard burst into my room carrying a small box. He danced round and round the room shouting, ‘I’ve done it! I’ve done it!’”” (http://www.yonkershistory.org/arms.html). He is shown (upper right) in 1947 revisiting his bedroom in Yonkers where he made this discovery.
He later becomes a Columbia professor and invents other transformational circuitry and devices, including FM radio (1933).
