He was hired in October 1948 by Dr. Gustaf Lindskog, Chairman of the Department of Surgery, and was assigned to supervise the Surgical Laboratories and the Section of Cardiac Surgery (Cardiovascular). He was given the assignment of serving as thesis advisor to William Sewell, a student at Yale School of Medicine who was working on a required research project in which he was attempting to develop a heart pump. The original pump that was developed used components costing a total $24.80, which included a number of standard laboratory supplies, some assorted hardware and an Erector Set. Glenn and Sewell presented the results of their experiments at the 1949 annual congress of the American College of Surgeons in Chicago. The model they presented took over the functions of the heart's right side, taking deoxygenated blood to the lungs. They reported that they had kept animals alive for up to 90 minutes using their device, without significant changes in blood pressure or oxygen saturation. The device created using the Erector Set is on display at the Smithsonian Institution's National Museum of American History. The Smithsonian acquired the heart pump in 1959 from Sewell's mother.
