Magness was born March 18, 1920, to Arthur J. and Marguerite Gray Magness and graduated from the University of Delaware in 1942. Two years later, he enlisted as a Private in the United States Army Air Corps. Magness was married twice, first to Elizabeth Pauline Weldin (born November 14, 1919, died 26 December 1989) with whom he had three daughters, and then to Anne (born November 22, 1923, died August 15, 2003), with whom he had another three daughters. In 1952, he founded the Magness Construction company.
