Indeed, John Logie Baird, the Scottish Superstar engineer, first demonstrated a working mechanical TV system on Jan 26, 1926, and then through many subequent improvements to the original system, the first electronic color television picture tube!
A quick search for his name at the European Patent Office returns no less than 210 patents (including 162 British patents and the remaining filed in France, Germany, Switzerland and Canada)!
