George Squier wrote and edited many books and articles on the subject of radio and electricity. An inventor, he and Dartmouth professor Albert Cushing Crehore developed a magneto-optical streak camera "The Polarizing Photo-chronograph" in 1896 to measure the speed of projectiles both inside a cannon and directly after they left the cannon barrel. This was one of the earliest photonic programs. They also worked to develop synchronous AC telegraphic systems. His biggest contribution was that of telephone carrier multiplexing in 1910 for which he was elected to the National Academy of Science in 1919.
