Quoting from the Blog

“In its 100-year history, General Motors has made significant contributions to society extending far beyond the automobile industry. One of these important contributions was the development of the first mechanical heart pump in 1952.”

Looking at the pump is fascinating . Never imagined GM was a company who had a “Heart”, but they did and probably still do.
