7 Segment display
I had limited contact with electronics, beyond consumer level, before the eighties. I'd seen Nixie tubes but I don't remember seeing seven segment displays before calculators and consumer electronics made them ubiquitous.
![]() Of course they're everywhere now but I was surprised they were patented in 1908. Seems they played out of town doing Summer Stock, Reparatory and maybe the Borsht Belt, paying their dues before they hit the big-time.

The OCR on the page for the 1908 patent is bad, but the scans are interesting. It was apparently intended as a military signaling device for artillery. The first digit couldn't be more than 1, and the last two could be 00 or 50.
