Who invented the mute button?

I love the mute button on our television remote control. We haven't listened to an advertisement for decades. Apart from our personal use, one of the most marvellous contributions it has made to the world was in today's final presidential debate. I wish I had had it in my hand. I would have used it more often but it certainly saved us from the unacceptable interruptions we had to endure last time from the President. It was wonderful to see its effect.

So who was the wonderful person who invented the mute button because I want to drink a toast to her/him this evening. Wikipedia to the rescue. Well it turns out it was Eugene Polley (1915 - 2012). At the age of 20 he was hired as a stock boy for Zenith Electronics he moved to the company's parts department, where he created the company's first catalog, then transferred to engineering, where his assignments included work on radar during World War II for the US Department of Defense. His 1955 invention, marketed as the Flash-Matic, used visible light to remotely control a television outfitted with four photo cells in the cabinet at the corners of the screen. Aiming the pistol-shaped control at an individual photocell could turn the receiver on and off, mute the sound and change the channel up or down. Thank you Mr Polley.
