Guy Johnson, Jr.

Guy Johnson, Jr. recently of Masonville CO passed away peacefully on August 30, 2017, at Hillcrest of Loveland, surrounded by loving family members and care givers. Guy's wife of 57 years, Jean, preceded him in death in 1999.

Guy was born on March 11, 1922, in Dallas TX to Guy Johnson and Flossie Josephine Posey. He had a brother, Jerry, and a sister, Marge.

For over 30 years, Guy served as a faculty member and taught mathematics, first at Rice University and later at Syracuse University in New York until his retirement in 1987.

Guy retired to the village of Spencer near Ithaca NY where he designed and built a retractable roof observatory. When Guy moved from Spencer to Masonville CO he donated his telescope to the Little Thompson Observatory (LTO) in Berthoud CO where he enjoyed observing the heavens with it on many public star nights.

Guy is survived by his three children: Guy Johnson III, Kenneth Norman Johnson, and Bonnie Jean Johnson of Masonville CO. His grandchildren include Devin Johnson, Sarah Johnson, Justin Johnson and Leo McManus of Denver CO. Guy's great grandchildren are Gwen and Layla Johnson.

A Celebration of Life for Guy will be held October 14 at the Little Thompson Observatory. Visit for details or to make a donation to the LTO so others can continue to share Guy's love of the stars.

As I am retiring on June 1, 2020, my mind goes back to old friends and coauthors. Guy was both. His wife Jean and Guy stayed in my house and looked after five kids for us for a month in 1975. Jean was terrific. I last visited them in Spencer in 1993 (about) and shared an evening with Guy in his observatory. I would like to add my congratulations here to both of them for leading great lives with lots of compassion for other human beings. Karl Gustafson, Boulder.

Professor Johnson taught me a great deal of stochastic mathematics in just one course on statistics during Fall 1979. He exuded passion for his work, he was a demanding and fair grader, and he was always a gentleman. That one course empowered me with for most of the mathematics content of my doctoral work at Syracuse and my current work in finance. I remember how graceful he was when he introduced me to his late wife Jean when just ran into each other in '87 at O'Hare Airport. He remembered my name too, eight years after the course! We had a delightful chat for about ten minutes as we were all rushing to catch our planes. With respect and gratitude. Mehmet Yanilmaz, Chicago, SU EE' PhD '87
