Who invented automated external defibrillators?

The AED is just a "democratisation" of a medical device used in hospital.

The real "invention" was the use of a electrical shock to stop an heart arythmia. I don't remember his name, but an American did the first test on a animal in the early 40ies.

Doctor Claude Beck made and succeeded the first test on a young boy in the late 40ies with a device created by a friend of him.

If you ever know the missing names, please, could you improve this topic ?

The defibrillator was invented by Dr. William Bennett Kouwenhoven and a team of medical colleagues in 1933, in the basement of Shaffer Hall. Koewenhoven noted that a low-voltage electrical shock caused a ventricular fibrillation in humans, a process where the heart ceases beating, but continues to quiver, or fibrillate, rapidly.
