CONWAY, Ark. (September 25, 2024) — The Hendrix community is saddened by the passing of retired Professor of Physics Dr. Robert “Bob” Dunn, who died on September 22 in Chandler, Texas. Dunn taught at Hendrix from 1988 to 2016, following a 20-year career in the United States Air Force that included earning his Master of Science in Physics from the Air Force Institute of Technology and his Ph.D. in Physics from the University of New Mexico.

While at Hendrix, Dunn secured at least four National Science Foundation grants, plus numerous others from the Arkansas Space Grant Consortium. He was well known for engaging students in research, particularly in work that focused on using the College’s ring laser to detect earthquake and tornadic activity.

“He, and others in chemistry and physics, were important players in creating a strong culture of undergraduate research at Hendrix,” said Cynthia Cook Sandefur Odyssey Associate Professor of Physics Dr. Julie Gunderson ’06. “Bob really believed that the best way to learn physics was by doing physics, and he provided many opportunities for Hendrix students to do physics research over the years.”

Dunn’s contributions to the strength of the department continue, with 60 percent of the current Department of Physics having taken classes from Dunn, and another faculty member receiving word from him about an opening at Hendrix. 

“Bob was the person who let me know that Hendrix was hiring a physicist in 1998, and he encouraged me to apply,” said Professor of Physics Dr. Ann Wright, who met Dunn while she was a post-doctorate researcher at UA Little Rock. “I am grateful that he did, because I got the job and have been here ever since.”

While Wright can share stories of Dunn’s adventurous spirit in the lab, her most frequent memories of him come from his folksy sayings. “‘Nervous as a long-tailed cat in a room full of rocking chairs’ was my favorite,” she says.

Associate Provost and Professor of Physics Dr. Todd Tinsley ’98 agrees with Wright about Dunn’s way of speaking. 

“My favorite was, ‘And if you can do that, I’ll carry your bags to Stockholm.’ I also loved, ‘I’m afraid you’re traveling down the well-worn road to mathematical perdition,’” Tinsley said. “The Stockholm line was his clever way to say, ‘That’s not allowed in physics’ without saying, ‘that’s wrong!’ But honestly, it was the very first time I ever heard anyone ever suggest, even in a light-hearted way, science isn’t set in stone. That physicists get surprised every now and then, and that’ll win somebody a Nobel Prize.” 

Tinsley now uses the Stockholm line in his own classroom, and says he learned more from Dunn in his years as a colleague than as a student. “Bob had some teaching experience in K-12 education, and he would freely share lessons he learned there about the importance of decentering yourself when teaching,” he said. “He had an example-driven teaching philosophy about how students build knowledge that was particularly well-suited to students who were novice learners.”

Gunderson, like Tinsley, attests that learning from Dunn outside the classroom had an impact on her life: “I knew Bob for many years before I was a student at Hendrix because we went to the same church,” she said. “At church, Bob was a beloved Sunday School teacher who knew a lot about the historical context of the Bible, and I knew him to be very sincere and devout in his Christian faith.

“So, from the Hendrix motto perspective, Bob lived a full and well-rounded life: He was a Christian, husband, father, grandfather, teacher, and mentor.”

A visitation will be held Friday, September 27. Read the full obituary here.
