Duke was a fourth-year surgery resident at Parkland Hospital the day President John F. Kennedy and Texas Governor Connally were shot and rushed to that hospital. Upon their arrival, Duke says, "It didn't take long to appreciate the gravity of the situation." When asked what can you do for him, he said, "I can't do much for a dead man." He is credited with saving the life of Governor Connally. Duke's academic career began in 1966 as an assistant professor of surgery at
UT Southwestern Medical School and later at the
Columbia University College of Physicians and Surgeons in New York. He also took some time to pursue graduate studies in chemical engineering, biochemistry and computer sciences at
Columbia University under the auspices of an NIH Special Fellowship. While Duke was an assistant professor of surgery in New York, he spent two years from 1970 to 1972 in
Jalalabad, Afghanistan, as a visiting professor and later chairman of surgery at
Nangarhar University School of Medicine. After returning from Afghanistan, Duke joined the faculty of
McGovern Medical School (formerly the University of Texas Medical School at Houston), where he was a professor of surgery. Among his many responsibilities, Duke served as special assistant to the president of the UT Health Science Center and held one of the distinguished professorships at McGovern Medical School as the John B. Holmes Professor of Clinical Sciences. He established Houston's Hermann Hospital
Life Flight operations in 1976 and helped establish its trauma and emergency services, of which he served as director. He was 86 years old. ==Recognition==
