James Michael Hillenbrand, 75, passed away on July 8, 2026, in Kalamazoo, Michigan.
Born on February 12, 1951, in Syracuse, New York, Jim was the second-oldest child of James Leonard Hillenbrand and Sarah Guinto Hillenbrand. He grew up in humble circumstances and took great pride in helping care for his younger siblings. His mother often remarked that he had a natural way with children, a quality that later made him a devoted father, grandfather, coach, and teacher.
Jim was a 1969 graduate of Liverpool High School, where he was an accomplished track and football athlete. His interest in learning was sparked late in high school and went on to shape the course of his life. He earned bachelor’s and master’s degrees in speech and hearing sciences from Indiana University and a Ph.D. in speech and hearing science from the University of Washington. There, he studied under Patricia Kuhl and conducted research on speech perception in infants.
Jim began his academic career at Northwestern University, serving as an assistant and associate professor from 1980 to 1985. He later became Director of Research for the Intelligent Systems Division of RIT Research Corporation in Rochester, New York, from 1985 to 1988, while also holding an adjunct appointment in the graduate computer science department at Rochester Institute of Technology. He then joined the Department of Speech, Language and Hearing Sciences at Western Michigan University, where he spent three decades teaching undergraduate and graduate students and conducting internationally recognized research in experimental phonetics, speech acoustics, auditory science, and speech perception.
Jim was a beloved instructor who connected easily with his students. His humility, approachability, humor, and ability to make complex ideas understandable left a lasting impression on many students. He cared deeply about their learning and treated them with the same curiosity and respect that guided his research.
Over the course of his career, Jim authored more than 50 journal articles and book chapters. His work was widely cited, and one of his papers on speech acoustics received more than 3,000 citations. His research was supported by nearly $6 million in grants from the National Institutes of Health. His scientific collaborators included Bob Houde, Rob Gayvert, Terry Nearey, and Jim Flege.
Jim received numerous honors for his contributions to research and teaching, including Northwestern University’s Teaching Excellence Award, the Journal of Speech and Hearing Research Editor’s Award, Western Michigan University’s Distinguished Faculty Scholar Award, and election as a Fellow of the Acoustical Society of America. One of his papers was selected for inclusion in Classics in Voice and Laryngology. Among his most memorable achievements was receiving a 2006 Ig Nobel Prize for research explaining why people dislike the sound of fingernails scraping across a chalkboard. The distinction perfectly suited his keen sense of humor and appreciation for irony.
Jim was known not only for his intellect, but also for his humble and approachable nature. He especially valued his long friendships with colleagues Jim Leja, Mick Hanley, and Steve Tasko, with whom he shared countless stories and laughs over the years. Lunchtime runs and racquetball games were a valued part of both his workday and his friendships.
Jim met his wife, Kathy, at Northwestern University. They married on August 18, 1984, in Glenview, Illinois. Their son Patrick was born in Rochester, New York, and their children Michael and Katie were born in Kalamazoo, Michigan. Jim and Kathy raised their family on a seven-acre property in Vicksburg, Michigan, which Jim fondly called “The Big Yellow House.”
Jim was an exceptional and deeply involved father. He coached all three of his children in Little League and spent countless hours behind the pitching machine helping them practice. He loved playing sports with his children, including baseball, tennis, racquetball, and badminton. He approached parenting as a true partnership and brought patience, humor, encouragement, and enthusiasm to family life.
Bicycles were another lifelong source of joy for Jim. He commuted by bike, took tandem rides with his children, and enjoyed peaceful solo rides along the country roads surrounding the Big Yellow House. Whether cycling for transportation, family time, exercise, or simple relaxation, riding a bicycle remained an important part of his life.
Jim also shared a particularly close bond with his older brother, Bill. The two exchanged frequent emails and phone calls, often talking about baseball and retelling family stories. Jim especially enjoyed the comical family tree Bill created, which traced the Hillenbrand family all the way back to the druids.
Outside of his academic work, Jim loved listening and dancing to swing music, watching films, especially older films and the work of Alfred Hitchcock, following tennis, and finding humor in the contradictions and absurdities of everyday life. When he retired from Western Michigan University in 2018, he said he planned to continue his research and writing, travel to film festivals and tennis tournaments, and learn to fly-fish, hit a topspin forehand, and pursue “other things that will never actually happen.”
After retirement, Jim found his greatest joy in spending time with his five grandchildren, Isabel, Ada, Kelly, James, and William. He delighted in watching them grow and brought to his role as a grandfather the same warmth, humor, curiosity, and natural connection with children that had been evident throughout his life.
Jim is survived by his wife, Kathy Hillenbrand; his children, Patrick (Tracy), Michael, and Katie; his grandchildren, Isabel, Ada, Kelly, James, and William; and his siblings, Tricia, Kathy, Dan, and Tom. He was preceded in death by his siblings, William “Bill” Hillenbrand and Joan Ellen “Joni” Hillenbrand.
In lieu of flowers, the family invites memorial contributions to Cure Alzheimer’s Fund, World Central Kitchen, the James and Kathryn Hillenbrand Scholarship (https://secure.wmualumni.org/s/giving?funds=SJKH&c=CoAL&drive=*), or the Montgomery Essential Needs Fund (https://secure.wmualumni.org/s/giving?funds=SINS&c=CoAL&drive=*).
Jim’s life’s work advanced the understanding of speech and hearing, but his greatest legacy is found in the family he loved, the students he inspired, the colleagues he supported, and the many people who were fortunate enough to share in his intelligence, humor, humility, and kindness.
