Orrin Squire Wood (December 14, 1817 – June 22, 1909) was one of the early pioneers of the telegraph industry in the United States and Canada.
He also oversaw the building of the line between Albany, New York, and Utica which opened in early 1846, the beginning of the rapid expansion of the telegraph in North America.
In 1847, he was recruited to be president of the newly formed Montreal Telegraph Company, which rapidly established lines to Toronto and, Quebec City, and then New York in August 1847.
Duggan House, a mansion in Montreal now owned by McGill University, was built for Wood in 1861.
[4][5][6] Having long outlined Morse, Alfred Vail, and Cornell, he was noted to be the "oldest living telegrapher" in his final years.
