This week, the first physical memorial to a New Zealand veteran of the Spanish Civil War will be unveiled in Cromwell. The plaque, which has been funded by a group of practicing and retired NZ surgeons, will mark the service of Douglas Waddell Jolly (1904 -1983), considered one of the great war surgeons of the 20th century. He made significant contributions to trauma surgery, especially for abdominal injury, and operated closer to the front line than ever thought possible. His work informed medical services in WW2, Korea and Vietnam. Kim talks to historian Mark Derby about Doug Jolly's enduring legacy.
