Terrence G Peterson

Terrence G. Peterson, born October 18, 1943, at St. John’s Hospital in Springfield, Missouri, passed away on March 5, 2026, of natural causes. He lived life entirely on his own terms, entering the world with nothing yet departing with a wealth of meaningful memories. Through a lifetime of opportunities and challenges, he cultivated his strengths and worked to overcome his limitations. In a word he himself chose, his life was tremendous.

He is survived by his two daughters, Shaina and Alyssa, whom he loved deeply and in whom he took great pride. Terrence also cherished a small circle of friends whose company, conversation, and counsel meant a great deal to him. He remained connected to many former students and took quiet satisfaction in knowing he had contributed to their growth and accomplishments.

Born the son of Neil Terrence and Eden Olivina (Byler) Cotner of Camdenton, Missouri, Terrence was the first in his family line born in a hospital. His family moved to Godfrey, Illinois, in 1949 when his mother’s second husband, John I. Peterson, purchased Valhalla Memorial Park. He grew up in the white house just inside the cemetery gates and legally took the Peterson name in 1960. Though John did not formally adopt him, Terrence always credited him with raising him.

In accordance with his wishes, Terrence’s body was donated to science so that he could continue to support teaching and learning even after his passing. He will be remembered by those who knew him for the way he lived—authentically, thoughtfully, and without apology.
