Bernard J. Miller: MD, ScD. (Hon), FACS: Lifelong Surgeon-Scientist and Critical Contributor to the Gibbon Heart-Lung Machine.

Bernard J. Miller, MD, ScD. (Hon), FACS, is known as a critical contributor for his work in the John H. Gibbon, MD, laboratory for his work on the heart-lung machine (HLM). In this setting, Dr. Miller developed the fluid control servo system, which was necessary to prevent malfunctioning of the HLM and prevent air emboli. Additionally, Dr. Miller assisted in conceiving and testing the left ventricular vent, the positive-negative pressure ventilator, and the HLM oxygenator; these inventions were all the product of extensive collaboration between the International Business Machines Corporation and the members of Dr. Gibbon's laboratory. Furthermore, Dr. Miller was a surgical assistant and perfusionist in the first successful open-heart surgery. Herein, we seek to describe Dr. Miller's story and his contributions to the HLM, as well as the contributions that were developed by the laboratory at that time. Additionally, we describe critical events leading up to the first successful use of the HLM on May 6, 1953, including a previously unreported use of the HLM for partial bypass of the right heart at Pennsylvania Hospital in 1952. Finally, we present the rest of Dr. Miller's professional and personal successes after his work on the HLM ended.
