How did john logie invented the television?

Answer 1

John Logie Baird and the invention of the television are part of History. But the idea of the television did not start with Logie Baird in the 1920's. In the late C19th, a number of scientists had made important discoveries that Baird would use in his first version of a television. Henri Becquerel found that light could be changed into electricity and, importantly, Ferdinand Braun had invented the cathode ray tube. By the 1920's there were 50 serious attempts to invent the television from Russia, America, Germany, Britain and Japan. Many researchers had well resourced and staffed laboratories but the man who invented the television did not.

John Logie Baird was born in 1888 near Glasgow. He had made money selling socks and soap. This business he sold off to follow his dream of inventing a television. It became an obsession and to survive he had to borrow money from friends and use whatever materials he could including scraps. By 1925, he was ready to give the first public display of a working television. The chosen place was Selfridges in Oxford Street, London. Shoppers saw slightly blurred but recognisable images of letters
