Father Thaddeus J. Burch passed away May 14, 2024 in Wauwatosa, WI. He was 93 years old, a Jesuit for 75 years and a priest for 62 years. His life combined his deep religious faith with a quest and appreciation for the world of physics. In addition to his two bachelor’s degrees in philosophy and theology, he earned bachelor’s and master’s degrees in physics and then a PhD at Fordham University. His PhD thesis on “A Nuclear Resonance Study of Order-Disorder in Ferromagnetic Alloys” was completed in 1968 under the direction of Professor Joseph Budnick. In 1974, Joe left Fordham to become the department chair in physics at the University of Connecticut and Thaddeus joined him as a visiting professor and a member of the Institute of Materials Sciences from 1974 to 1976. The research they completed together over the years led to 41 peer-reviewed journal articles that used NMR to probe ferromagnetic materials. Father Burch later joined Marquette University and was a professor of physics, physics department chair, and dean of the graduate school. Professor Budnick remembers Father Burch as “a dedicated and gifted student at Fordham and a creative and interactive researcher in the lab. He was a genuinely wonderful person in every way.”
