Isaac Shoenberg (1880-1963) was Director of Research at the Electric and Musical Industries (EMI), responsible for creating the team which developed the world's first all-electronic television system. Previously a 150-line system had been used, but Shoenberg decided to use a 405-line high definition standard. This was so succesful that it was taken on as the British standard in 1935. Regular broadcasts followed two years later. This standard was superseded in 1985.
