Earl Bakken was an American inventor. He loved electricity and electronics. He studied electrical engineering at the University of Minnesota.

In the 1950s, doctors used large tools to help hearts. These tools needed to stay plugged into walls. One day, a power blackout happened. A young patient died because the tool stopped working. This was a very sad event.

Dr. C. Walton Lillehei asked Bakken for help. Bakken found a diagram for a metronome. A metronome is a tool that keeps a steady beat. He used this idea to make a new pacemaker. This device was small. It was about the size of card decks. It used a battery for power. Because of the battery, a person could wear it.

Bakken started a company called Medtronic. He started it in a small garage. The name comes from the words "medical" and "electronic." Medtronic helped make tools that doctors could put inside the body. Bakken also started a museum called The Bakken. It is in Minneapolis. It shows how science and electricity work together.
