Ezra Cornell

Ezra Cornell was born in Worchester County, NY in 1809. His early career as a plow salesmen gave him a knowledge base to assist in a project to bury telegraph wires. He was later involved in the construction of telegraph poles connecting Washington D.C, Baltimore, and Maryland, the first substantial telegraph line to be constructed in the U.S. Cornell went on to make his fortune in the telegraph business as an associate of Samual Morse. To solve the problem of telegraph lines shorting out to the ground, Cornell introduced the idea for glass insulators at the point of connection between lines and pole.
