Dr. James (Jim) Francis Wunder

With deep love and sorrow, we announce the passing of Dr. James (Jim) Francis Wunder, son of Joe and Marion Wunder, born in Mason City, Washington, on October 7, 1938. A man of wisdom, compassion, and service, Jim lived a life devoted to medicine, his country, and his community.

Raised as a farm boy in Bison, South Dakota, Jim developed a strong work ethic and a deep respect for the land. These early years shaped his character and inspired a lifelong love of gardening and caring for trees,  hobbies that brought him peace and joy throughout his life.

After college Jim pursued his medical education at the University of South Dakota and the University of Minnesota, earning his medical degree in 1964. His commitment to learning and patient care laid the foundation for a distinguished career.

Dr. Wunder proudly served in the United States Air Force as a flight surgeon, caring for servicemen and women with dedication and skill. He later completed his radiology  residency at Wilford Hall Hospital, Lackland Air Force Base (San Antonio, Texas), one of the nation’s premier military medical centers.

After his honorable discharge as a Lieutenant Colonel from the Air Force, Dr. Wunder entered private practice in Mobridge, South Dakota, where he was known to everyone as “Doc”.  He practiced for 35 years as a board certified diagnostic radiologist. He was a clinical professor for the University of South Dakota and was bestowed the honor Fellow of the American College of Radiology.  He was a trusted friend, physician, colleague, and mentor. Known for his steady kindness, determination, meticulous demeanor and professional excellence, he was deeply respected by friends, patients and peers alike.

Jim shared a devoted life with his high school sweetheart Peg, his wife of 64 years, and together they raised a loving family. He is survived by his sons Daniel (wife Melinda), Stuart, and Walter (wife Stefinie), his daughter Jennifer, and 10 thriving grandchildren.

Beyond his professional accomplishments, Jim was a man of quiet passion, planting and tending to his trees, lawns, and gardens with the same care he offered his patients. His legacy endures in the countless lives he touched, both through his medical career and his personal warmth.

A celebration of life for Jim will be on October 18, 2025 from 12 to 5 PM at the Moose in Mobridge, SD.  Internment will occur at Fort Meade National Cemetery at a later date. In lieu of flowers, the family requests donations be made to the Arbor Day Foundation honoring his spirit and life long desire to “plant enough trees to cover a mountain”.

Dr. James Francis Wunder will be remembered as a healer, a patriot, and a man of great integrity whose memory remains a blessing.
