Carl Frey Constein was born in the eastern Pennsylvania town of Fleetwood. After working his way through college, he became a W.W. II aviation cadet and received his wings as pilot. He was sent to India to fly supplies and materiel to China over the Himalayan Hump. For his ninety-six round-trip flights he was awarded two Air Medals and the Distinguished Flying Cross. He recalled his year in the China-India-Burma theater in the memoir Born to Fly the Hump, published by 1st Books Library. After the war Constein earned a doctorate at Temple University in English and Educational Administration. He has been a teacher, curriculum director, education writer, and superintendent of schools. Constein lives outside Reading in Berks County, Pennsylvania. He lectures frequently about the Hump and the CBI to historical societies, aviation groups, library groups, and civic clubs. He is at work on a partly whimsical novel about an author whose books are published by a new breed of publishers.
