Velcro
Swiss electrical engineer George de Mestral invented his first touch fastener when, in 1941, he went for a walk in the woods and wondered why Burdock seeds clung to his coat and dog. He discovered it could be turned into something useful. He patented it in 1955 and subsequently refined and developed its practical manufacture until its commercial introduction in the late 1950s.
Oscilloscope history
The first Digital Storage Oscilloscope (DSO) was invented by Nicolet Test Instrument of Madison, Wisconsin. It was a low speed ADC (1 MHz, 12 bit) used primarily for vibration and medical analysis. The first high speed DSO (100 MHz, 8 bit) was invented by Walter LeCroy (who founded the LeCroy Corporation, based in New York, USA) after producing high-speed digitizers for the research center CERN in Switzerland. LeCroy (since 2012 Teledyne LeCroy) remains one of the three largest manufacturers of oscilloscopes in the world.
