The first supplier of telephones to Bell was a company established by Thomas C. Cowherd and his son James H. Cowherd, in a three-storey brick building in Brantford, Ontario, creating Canada's first telephone factory.[Note 1] Thomas and James had been good friends of Alexander Graham Bell, providing stovepipe wire with which Bell conducted his early telephone experiments from his father's home in Tutelo Heights, Ontario, and also building some 2,398 telephones to Bell's specifications for the Canadian market until James Cowherd's untimely death from tuberculosis in 1881.[1][18] With a government-granted monopoly on Canadian long-distance telephone service,[13] The Bell Telephone Company of Canada was serving 237,000 subscribers by 1914.
