Hal D. Simpkin grew up in rural St. Louis County and in Memphis, Tennessee. He graduated from Normandy High School in St. Louis. Hal has an M.S. degree in Business Management from Lindenwood University in St. Charles, Missouri, with undergraduate work done at the University of Missouri-St. Louis.
His two full-time employers were the United States Army and McDonnell Aircraft Corporation in St. Louis where he was a member of the Flight Test Division. Extensive writing was done for both employers.
A book entitled Paired Comparisons and Personnel Compensation: A Computer-Aided Approach was written as a required thesis for his postgraduate degree. A copy is in the library at Lindenwood University.
After retirement from McDonnell Douglas Corporation, Hal began writing for pleasure, both nonfiction and fiction. His nonfiction book, Captain William H. Thorwegen: A compilation of notes from Ruth Ferris, is in the Missouri Historical Society Library.
Hal’s first novel, G-Eye, was published by High Hill Press in 2009. In 2010, his short story Road to the World, a memoir, was selected by the St. Louis Writers Guild for inclusion in its anthology, St. Louis Reflections, honoring the organization’s 90th anniversary.
For a number of years, Hal served as a member of the Board of Advisors of St. Joseph Institute for the Deaf. He also formed and directed a corporation that designed and produced revolutionary classroom amplifiers for teaching of the profoundly deaf.
Hal and his wife, Chris, live in Missouri.
