Chart of the International Morse code letters and numerals. 1836 – William Fothergill Cooke invents a mechanical telegraph. 1837 with Charles Wheatstone invents the Cooke and Wheatstone needle telegraph. 1838 the Cooke and Wheatstone telegraph becomes the first commercial telegraph in the world when it is installed on the Great Western Railway.
Electrical telegraphy may be considered the first example of electrical engineering. [5] Electrical engineering became a profession in the later 19th century. Practitioners had created a global electric telegraph network, and the first professional electrical engineering institutions were founded in the UK and the US to support the new discipline.
Engineering advances in the 1880s, including the invention of the transformer, led to electric utilities starting to adopting alternating current, up until then used primarily in arc lighting systems, as a distribution standard for outdoor and indoor lighting (eventually replacing direct current for such purposes).
