Dr. Louis Eugene Haun Jr.

Louis Eugene Haun, Jr., beloved husband, father, and grandfather, 85, of Knoxville, passed away peacefully at home on Friday, February 13, 2026. Born on July 23, 1940, Louis was the oldest son of the late Dr. Louis Eugene Haun, Sr. and Jane Gray Haun. He graduated Cum Laude from the McCallie School in Chattanooga in 1958, where he was a member of the tennis team and an elite student. Louis met the love of his life, Katharine Alden Haun this same year and they were inseparable for the rest of his life. He continued his tennis career at the University of Tennessee, where he served as captain of the team. Life wasn’t just about tennis though. He continued to be serious about his studies, becoming a member of Phi Beta Kappa and he also found time to be social as a member of Sigma Chi Fraternity. Louis and Kay married in 1963 and, after graduating from the University of Tennessee in three years, he and Kay moved to Memphis where he attended the University of Tennessee Medical School. He excelled in Memphis as well and was inducted into both Alpha Omega Alpha and Phi Chi honor societies. After graduating from medical school in 1964, Louis trained at the University of Tennessee and Vanderbilt University Hospitals. Dr. Haun felt strongly about serving his country and he joined the Air Force as a member of the 62nd Flight Interceptor Squadron stationed at K.I. Sawyer Air Force Base in Michigan, where he served for two years as a flight surgeon. He and Kay then moved to Cincinnati, Ohio where he began his residency in Ophthalmology at the University of Cincinnati. The family then moved to California where Louis did post graduate work at Stanford University before settling back home in Knoxville, where Louis joined an ophthalmology practice in Maryville, Tennessee in 1972. Dr. Haun was a man of exceptional kindness and generosity known for his gentle spirit, his ability to listen without judgement, and his deep love for those around him. He was a great family man, always putting his loved ones first and quick with a joke or story. In addition to being a dedicated physician, Louis had a passion for life that extended far beyond his practice. He was an avid tennis player, always on the court with a smile. He loved watching his three sons compete, whether it was on the tennis court or swimming pool. He was a voracious reader, with an insatiable curiosity and love of learning. His interests were diverse, and he believed in the power of knowledge. Above all, Louis made it his life’s work to make people happy. Whether through his caring words as an eye doctor, his warm presence as a friend, or his uplifting energy as a family member, he brought light to everyone around him. He never met a stranger – only a friend he hadn’t made yet. Louis was preceded in death by his parents, his brother Walker Gray Haun, his son Christopher Cartwright Haun, grandson George Haun and his parents in law Scott Alden and Katharine Taylor Alden. He is survived by his wife of 62 years, Katharine Alden Haun (Kay), son Louis Eugene Haun, III, (Deven) of Louisville, TN, Alden Kirkpatrick Haun (Ashley) of Knoxville, TN; seven grandchildren Robert Taylor Haun, Katharine Alden Haun, Louis Eugene Haun, IV, Adelaide Elizabeth Haun, Charlotte Haun, Grace Haun, and Caroline Haun and his sister Caroline Haun Nowell.
