The flip-flop turns 100 this week

I got this from the slowspeedwire Yahoo group:

IEEE Spectrum published an article earlier this week that describes how the
original flip-flop circuit was designed and built. According to the
article, Re-creating the First Flip-Flop, the circuit was first invented in
1918 and used as a trigger relay for radio designs. An article in the
December 1919 issue of The Radio Review popularized the circuit, which used
two vacuum tubes!
