George Ashley Campbell
From Wikipedia, the free encyclopedia
George Ashley Campbell (November 27, 1870 – November 10, 1954) was a pioneer in developing and applying quantitative mathematical methods to the problems of long-distance telegraphy and telephony.
He graduated from MIT in 1891, and then received a master’s degree from Harvard University in 1893. He then spent spent three years doing graduate work at Göttingen, Vienna, and Paris. In 1897 he went to work for the American Telephone and Telegraph (AT&T). He developed a method for transmitting analog telephony over long distances. Engineer Michael Pupin also patented a similar system, and AT&T paid Pupin $435,000 for his patents, so that development would continue without a legal battle.
