In an attempt to record the sound of a heartbeat, Dr. Wilson Greatbatch inadvertently created something far more crucial—a device that emitted electricity pulses to the heart. It was this discovery that led to the implantable cardiac pacemaker and distinguished Greatbatch as having created one of the most significant inventions of the 20th century. In 1996, he was honored with the Lemelson-MIT Lifetime Achievement Award.
