Utility poles seen outside the Gardner Building, in Toledo, Ohio, 1895. The system of suspending telegraph wires from poles with ceramic insulators was invented and patented by British telegraph pioneer William Fothergill Cooke. Cooke was the driving force in establishing the electrical telegraph on a commercial basis.
The term lineworker was used for those who set wooden poles and strung wire. The term continued in use with the invention of the telephone in the 1870s and the beginning of electrification in the 1890s. This new electrical power work was more hazardous than telegraph or telephone work because of the risk of electrocution. Between the 1890s and ...
Oppenheimer poles can still be found along the route of the former Australian Overland Telegraph Line, and in Queensland and Western Australia. Oppenheimer poles can also be found repurposed as flag poles, or in the case of the William Creek Hotel, as verandah supports. There is also an Oppenheimer pole outside the Daly Waters pub.

[ 99 ] Even before the war, the American Telegraph Company censored suspect messages informally to block aid to the secession movement.
They are often made of wood, such as old railway sleepers, telegraph poles or even tree trunks. For a longer 'life' more resilient iron girders or pipes may be used and concrete posts are sometimes employed. The older examples were often made of stone, such as granite, whinstone, sandstone or limestone.
Early undergrounding had a basis in the detonation of mining explosives and in undersea telegraph cables. Electric cables were used in Russia to detonate mining explosives in 1812, and to carry telegraph signals across the English Channel in 1850. [1] With the spread of early electrical power systems, undergrounding began to increase as well.
