There he was able to perfect a device to start large gas engines with high pressure-gas and develop hoisting apparatuses for deep wells. Sutton's mechanical aptitudes never left him. His father finally directed him to return to his medical studies and he did so returning to Columbia University in 1905. Sutton's medical studies proceeded through the College of Physicians and Surgeons at Columbia University. While he continued to work on patents associated with oil drilling, Sutton also began at this stage to apply his mechanical aptitude to improving medical instruments. With credit for his graduate studies at both the University of Kansas and Columbia University, Sutton obtained his doctorate in medicine in 1907 graduating with “high standing”. He then began an internship at Roosevelt Hospital in New York working in the surgical division headed by Dr. Joseph Blake. Career In addition to his clinic duties at Roosevelt Hospital, Sutton was also able to work with the Surgical Research Laboratory at the College of Physicians and Surgeons. With that support, he was able to begin developing and improving a variety of medical and surgical practices including improving anesthetic techniques, and perfecting abdominal irrigation. In 1909, Sutton returned to Kansas City, Kansas where his family had relocated and his father and brother were in law practice. Sutton was appointed assistant professor of surgery at the four-year-old University of Kansas Medical School. The tenuous nature of the appointment at the young school led him to also maintain a private practice and serve on the staff of St. Margaret's Hospital as well as the university's Bell Memorial Hospital. For six years, Sutton performed a wide range of surgeries carefully documenting the procedures. He published several articles related to these cases going back to his internship at Roosevelt. In 1911, he had accepted a commission as a First Lieutenant in the United States Army Medical reserve Corps. This eventually led to his taking a leave of absence from the university in February 1915 to serve at the American Ambulance Hospital outside Paris. Sutton and others from his days at Columbia and Roosevelt arrived at College of Juilly on February 23 where hospital facilities had been set up only 40 miles from the front lines of World War I. Within 2 months, he was surgeon-in-chief handling administrative duties in addition to his surgical responsibilities. His inventive aptitude was perhaps never more valued as he developed fluoroscopic
