History:
International Radio Telegraph Company was the struggling successor to Fessenden's National Electric Signaling Company (NESCO). In 1912, following a losing initial decision in a lawsuit initiated by Reginald Fessenden, NESCO had gone into receivership, reported in Marconi Competitor Bankrupt from the August 6, 1912 Wall Street Journal. During World War One, NESCO exited bankruptcy and was renamed International Radio Telegraph Company. The company was reported purchased by Westinghouse Electric in Westinghouse Company Enters Wireless Field from the October 16, 1920 Electrical Review.
