Dr. James Patton Slagle, MD, was born August 30, 1932, in Houston, Texas to Robert Alvin and Hazel Hoyt Cox Slagle. He passed away on July 16, 2025, at the age of 92. He was a longtime resident of Shavano Park (San Antonio). He attended Harvard Elementary (Houston), Brackenridge High School (San Antonio), The University of Texas at Austin and The University of Texas Medical Branch at Galveston. In his early years, he worked at the San Antonio CPS as a Meter Reader and also served in both the Navy and Army. After graduating from medical school, he was a General Practitioner in San Antonio and later retired as an Anesthesiologist. He was deeply loved by all who knew him. More than just an exceptional doctor, he was warm, kind, intelligent, playful, and always up for a good laugh — a quality that earned him the prestigious “Horses Ass” trophy at his medical school graduation. An outdoorsman at heart, he found joy in simply being outside. A passionate cyclist, he continued riding well into his 80s. His family will forever cherish memories of time spent at Medina Lake, ski adventures in Colorado, hikes through Big Bend, Longhorn football games, and quiet afternoons together on his back patio. He was an avid reader and a lifelong learner, always curious and engaged with the world. He had a deep love for animals, especially the many dogs who shared his life over the years. Music brought him great joy, from classical to country, though Ernest Tubb and Willie Nelson held a special place in his heart. Above all, he’ll be remembered for his remarkable sense of humor — a gift he shared freely and kept shining brightly until the very end. He was a long-time member of the American Medical Association, Bexar County Medical Association and was a Texas Exes Life Member. He was preceded in death by his parents, Robert Alvin Slagle and Hazel Hoyt Cox Slagle; his brother, Robert Slagle, Jr., Dorothy McMillan Slagle (1st wife), and Glynda Briggs Slagle (2nd wife) He is survived by his sons: James P. Slagle Jr and wife Juanita, and Robert H. “Pat” Slagle and wife Rachel, a daughter Diana S.
