The following is an excerpt from "The Architects of Golf" by Geoffery S. Cornish and Ronald E. Whitten (1993)
"Xen Hassenplug attended Ohio Wesleyan University and Toledo University, majoring in civil engineering. His first experience in golf course construction came in 1946, when he was involved in planning irrigation and seeding of an 18 hole course planned by J. B. McGovern at Overbrook CC near Philadelphia.
McGovern became ill during construction of the course, and Hassenplug went on to complete the 18 holes and then to assist golf architect Dick Wilson on two other Pennsylvania projects, Radnor Valley near Philadelphia and Westmoreland CC near Pittsburgh.
Upon completion of these layouts, Hassenplug entered private practice, combining golf course design, land planning, irrigation and civil engineering. Ed Beidel joined him in his practice in the 1980s."
