Wrong Resistor
In 1956, engineer Wilson Greatbatch was building an oscillator to record heart sounds at the University of Buffalo. He accidentally grabbed the wrong resistor from his parts box. Instead of recording heartbeats, the circuit produced electrical pulses that mimicked the heart's rhythm. Greatbatch immediately recognized the potential: a small, implantable device that could regulate irregular heartbeats. He spent two years perfecting the design in his barn workshop, and on June 6, 1960, the first successful implantable pacemaker was installed in a patient. The device worked for 18 months. Today, over 3 million people worldwide depend on pacemakers, with more than a million implanted each year. Hosted on Acast. See acast.com/privacy for more information.
