Jon "Mike" Michael Dunn

June 19, 1941April 5, 2021

Jon Michael “Mike” Dunn, age 79, of Bloomington passed away peacefully on Monday, April 5, 2021, with his family at his side. Born June 19, 1941 in Ft. Wayne, Indiana, he was the son of John and Philomena (Lauer) Dunn. He met his future wife, Sarah Jane “Sally” (Hutchison) Dunn in 1959 during their first week as students at Oberlin College, from which he received an A.B. in philosophy in 1963. He went on to the University of Pittsburgh to receive a Ph.D. in philosophy (logic) in 1966 and then served on the philosophy faculties of Yale University and Wayne State University before coming to Indiana University in 1969.

Mike worked at IU for nearly forty years as a faculty member, researcher and administrator, serving twice as chair of the Department of Philosophy, as the first executive associate dean of the College of Arts and Sciences and as the founding dean of the School of Informatics, now the Luddy School of Informatics, Computing, and Engineering. After his retirement from IU in 2007, he continued his research and service work until very recently.

He was the author or co-author of six books and over 100 papers and chaired 17 doctoral dissertations in philosophy, cognitive science, computer science and mathematics at IU. His many research areas included information-based logics, the relations between logic and computer science, algebraic semantics and quantum logic.

Among other honors and appointments, he was a Fellow of the American Academy of Arts and Sciences, Fellow of the American Council of Learned Societies, President of the Society for Exact Philosophy, on the Executive Committee of the Association for Symbolic Logic, editor of the Journal of Symbolic logic, and chief editor of the Journal of Philosophical Logic. On his retirement, he received the IU Bloomington Provost’s Medal and was appointed a Sagamore of the Wabash by the Governor of Indiana.

Mike and Sally were world travelers, often in connection with Mike’s work, which led him to visiting and consulting positions at Oxford University in England, the Australian National University, and the University of Dubai, among others. He enjoyed keeping in touch and spending time with his many friends and colleagues around the world and in Bloomington.

He took pleasure in gardening, travel, historic preservation, and spending time with his family, especially his grandsons. He enjoyed living in Bloomington very much, taking full advantage of its many cultural events and attractions, especially the IU Opera Theater and Eskenazi Museum of Art.

Locally, Mike served on the board and as board chair of HealthLINC, on the board of Bloomington Restorations, Inc., and as president and vice president of the Old Northeast Downtown Neighborhood Association.

Mike is survived by his wife, Sarah Jane “Sally” Dunn, of Bloomington, to whom he was married on August 8, 1964; one son and daughter-in-law, Jon William Butcher Dunn and Erin Butcher Dunn, of Bloomington; his daughter and son-in-law, Jennifer Anne Dunn and John A. Knight, of Indianapolis and two grandsons, Samuel Aten Dunn and Rowan Dunn Knight. He was preceded in death by his parents, one brother, James Dunn and one sister, Patricia Resac.

We are very sorry to hear of Mike's passing. We knew him in different capacities. Chris has fond memories of his interactions with Mike in Informatics, and I have always known him to be a superb human being. Please share our condolences with your family.

Dearest Sally & family,
So sorry to hear of Mike’s passing, I worked with him for many years. He was a very kind man, a wonderful colleague & friend and I will miss him. When I came to work in Informatics in 2001, I had met him previously in the College, but only briefly, starting the new school was a great adventure with Mike as Dean, he always stopped by “just to say hi” & make sure we had what we needed. After he retired he still did when he was in the building! He loved gardening and flowers also, he will be missed. My sympathies to the family, treasure your memories & hold them close. He checked on me when my husband dealt with cancer & the effects of chemo and after he passed, I will never forget that,

Mike was the model academic citizen – seeing the potential in students and colleagues, and using his understanding and connections to help develop these talents. I enjoyed working with him on the proposal for the School of Informatics, where his attention and support made a major difference for the university and the field. My condolences to Sally and the family.

Dear Sally,
I am so sorry to hear of Mike’s passing.

This takes me back to the first time he and I met, at a gathering at Larry Campbell’s place, summer of 1980. I remembered fondly a logic course I took in college, and he recommended a text that I still have a copy of and that, in fact, I had just take off the shelf a week ago for another look.

He was always so friendly and gracious to me, mostly recently in impromptu chats with you and him at the Y.

This has to be a very sad time for you and family. My condolences to all.

Fondly,

David

Mike always treated the staff with kindness and real interest in their lives. I, for one, appreciated that during the many years I worked in the philosophy department. He was definitely one of the "good guys" on campus and will be missed.
