Kevin M. Callahan grew up in Elgin, Illinois. He received a B.A. in History from Yale University, where he also played football. After graduation, Kevin visited the American cemetery at Normandy and was struck by both the beauty of the grounds and the sacrifice of so many. Ten years ago, Kevin visited the Sicily-Rome American Cemetery in Italy with his wife and three young sons. Walking among the gravestones, they came across a pair of brothers buried side by side. He found the sight of the two brothers resting together to be especially poignant. It inspired him to find and tell the stories of all brothers buried side by side in American World War II cemeteries. Kevin also has an MBA from the MIT Sloan School and a Master's in International Affairs from the Columbia School of International and Public Affairs. He lives in Rowayton, Connecticut with his wife, three sons, and two dogs.
