John H. Gibbon

John H. Gibbon was an American physician and medical researcher known for developing the heart-lung machine in the 1950s, which enabled doctors to perform open-heart surgeries. His innovation allowed the heart to be temporarily disconnected from the body, maintaining blood circulation and oxygenation. This breakthrough revolutionized cardiac surgery, making procedures on the heart safer and more effective. Gibbon's work significantly advanced medical capabilities, saving many lives and opening new possibilities in surgery and cardiology.
