John Antonioli

September 14, 1984 — March 20, 2021

John Antonioli, age 36, of Bozeman Montana, passed away on Saturday, March 20th, 2021.

John was born on September 14, 1984 in Missoula Montana, the son of Joseph Thaddeus Antonioli (Ted) and Michele Cecelia Antonioli (née White). He was baptized at Anaconda Catholic Community by Pastor Frank McCormick, and sponsored by family friends Jim and Lorraine Tucker. He was confirmed in Missoula by Bishop Morlino and was sponsored by family friend Sister Kathleen O’Sullivan. He attended Sentinel High School, Montana State University (B.S. in Mathematics and M.S. in Mathematics) and the University of Victoria (PhD in Mathematics).

John was an extremely gifted mathematician and incredibly patient teacher. John’s love for mathematics was fostered from a young age by the Missoula schools, especially his teachers Sue Dolezal and Gary Little. In the Montana State University Department of Mathematical Sciences, John formed lifelong friendships, and was mentored by professors including Russ Walker, Marcy Barge, Richard Swanson, Warren Esty, Lukas Geyer, and Tomas Gedeon. At the University of Victoria, John had the exceptional fortune to work with the generous and brilliant mathematician Professor Anthony Quas, who mentored him in the completion of a dissertation on dynamical systems. After the completion of his PhD, he published in his field, and taught at Montana State University, California State University Channel Islands, and the University of Denver.

As a typical Montana boy, John spent many enjoyable days climbing mountains, hiking, and fishing with his grandfather and father, and later with his wife Medellee and their children. John also prospected for gold and silver in the mountains of Montana with his father and other geologists. John was an exceptional cook, and loved experimenting with new flavors, cuisines, and ingredients.

John married his high school sweetheart, Medellee Ester Antonioli (née Johnson) on August 6, 2005. Together, they traveled to nearly 40 countries. Medellee and John adopted their dog, Professor Biscuit, in 2009. They had two children, Clementine Josephine and Lukano (Lucky) Rosten. John took tremendous pleasure in spending time with his children, and it was beautiful to observe his relationship with the children blossoming as they grew older. John especially loved taking his wife and children on adventures in nature--hikes, visiting parks, and walking their dog.

John is survived by his wife, Medellee, his daughter, Clementine (age 5), his son Lucky (age 3), his parents, Michele and Ted, and his sisters, Kathleen and Clare. He is also survived by his in-laws Susan, John and Laureen, Charity, Amity, Justus and Ivy. He is also survived by many friends and a large and loving extended family.

There will be a graveside service on Saturday, March 27, at 10:00 a.m. at Old St. Mary’s Cemetery, Missoula Montana. A brief informal reception will follow at Playfair Park, Missoula.
