While at the University of Utah, Morgan wrote for its student literary publication, The Pen, and made as close friends, Helen Zeese (Papanikokas), Ray B. West, Richard Scowcroft, and Fawn McKay (Brodie). Upon graduation, he began working for the Utah Historical Records Survey and the Federal writers Project, was an advisor and contributor to Utah Historical Quarterly and wrote or edited more than forty historical works. Because he was deaf, his correspondance is both voluminous and memorable. Bill Mulder remembers his oral communications as \"an amaing stream of words in a high-pitched monotone in answer to written notes handed to him.\"
