Training
The training was basically self-taught , since from a very young age he had to combine school with various trades due to scarce family resources. He worked as a carpenter to pay for two years of study at Oberlin College (Ohio), where he became interested in the nascent applications of electrical energy .
Invention of the harmonic or musical Telegraph
In 1867 he registered his first patent for an improved telegraph apparatus , which was later followed by some seventy more inventions ; the most famous was the harmonic or musical telegraph , based on the vibrations of electromagnetic impulses.
He worked as a clerk in telegraph factories in Chicago and Cleveland , and in 1869 formed the Gray & Barton Company which, in 1872, became the Western Electric Manufacturing Company .
The phone
In 1874 he left his position with the company to devote himself entirely to research. The 14 of February of 1876 filed in the Patent Office a new device, the telephone, transmitting the human voice through the telegraph wire.
Curiosities
Alexander G. Bell also presented in the Patent Office an invention very similar to that of the telephone but he did it two hours later,; Gray then claimed paternity of the invention, although after several years of litigation Graham Bell was confirmed as its rightful inventor.
