Telegraph
Happening into the offices of the Maine Farmer in 1842, Ezra saw an acquaintance of his, one F.O.J. Smith, bent over some plans for a "scraper" as Smith called it. For services rendered, Smith had been granted a one-quarter share of the telegraph patent held by Samuel F.B. Morse, and was attempting to devise a way of burying the telegraph lines in the ground in lead pipe. Ezra's knowledge of plows was put to the test and Ezra devised a special kind of plow that would dig a 2½ foot ditch, lay the pipe and telegraph wire in the ditch and cover it back up as it went. Later it was found that condensation in the pipes and poor insulation of the wires impeded the electrical current on the wires and so hanging the wire from telegraph poles became the accepted method.
Ezra made his fortune in the telegraph business as an associate of Samuel Morse, having gained his trust by constructing and stringing the telegraph poles between Washington, D.C. and Baltimore, Maryland, as the first ever telegraph line of substance in the U.S. To address the problem of telegraph lines shorting out to the ground, Cornell invented the idea of using glass insulators at the point where telegraph lines are connected to supporting poles. After joining with Morse, Cornell supervised the erection of many telegraph lines, including a portion of the New York, Albany & Buffalo line in 1846 and the Erie and Michigan Telegraph Company connecting Buffalo to Milwaukee with partners John James Speed and Francis Ormand Jonathan Smith. Cornell, Speed and Smith also built the New York and Erie line competing with and paralleling to the south the New York, Albany and Buffalo line in which Morse had a major share. The line was completed in 1849 and Cornell was made president of the company.
Cornell's sister Phoebe married Martin B. Wood and moved to Albion, Michigan, in 1848. Cornell gave Wood a job constructing new lines and made Phoebe his telegraph operator, the first woman operator in the United States.
Cornell earned a substantial fortune when the Erie and Michigan was consolidated with Hiram Sibley and his New York and Mississippi Company to form the Western Union company. Cornell received two million in Western Union stock
Cornell was a Republican member of the New York State Assembly (Tompkins Co.) in 1862 and 1863; and of the New York State Senate from 1864 to 1867, sitting in the 87th, 88th, 89th and 90th New York State Legislatures.
