I'm surprised there wasn't a Google Doodle about him today.

While a brilliant engineer, it reads that his family relations were real headline makers.

Wow. Shocked

And yet not so young that you fail to appreciate the warm glow of the 866 or 872!  Especially when they twinkle with modulation.  The world's earliest (monochrome) color organ!

Therefore this arrangement - the best solution already built and working. Got some real PIV there along with the pulsating blue&UV glowz.

Holiday declared in honor of Peter Cooper Hewitt!

Because it falls on a Sunday this year, everyone will have Monday off to celebrate the appropriate lighting devices, rectifiers, and the glowing, ionized Mercury therein.
