Jack was born Feb. 9, 1928, in Arley, Texas, grew up in Bovina, Texas, and died Feb. 21, 2008, in Waxahachie, Texas. Known as Dr. Jack, Chief, Mox, O.D. and Cactus Jack, among other affectionate nicknames, Dr. Barnett was an outdoorsman and avid hunter, who was most content when surrounded by his horses and bird dogs. He was equally in his element when surrounded by his medical colleagues and students and he was cherished by his family and many friends. Dr. Barnett received his undergraduate degree from West Texas State College in 1948 and began a long career in education in Canyon, Texas, where he taught chemistry for the next four years. Following acceptance to Southwestern Medical School, he and his family moved to Dallas in 1952, where he also completed his internal medicine internship and residency. From 1958-1960, he was a post-doctoral research fellow of the National Institute of Allergy and Infectious Disease in the Department of Internal Medicine at the University of Texas Southwestern Medical School; he served his final year of fellowship in the Department of Immunology at the University of Pittsburgh School of Medicine. Dr. Barnett returned to the University of Texas Southwestern Medical School in 1961 where he served as co-director of the Infectious Diseases Fellowship Program and chairman of the Division of Public Health and Preventive Medicine and achieved the rank of professor of medicine. He held these positions until 1977 and then spent the next six years engaged in the private practice of medicine. In 1983, Methodist Hospitals of Dallas recruited Dr. Barnett to be chairman of the Department of Internal Medicine, program director of the Internal Medicine Residency Program and medical director of the Infection Control Department. He remained in these roles until 2002, when he served as associate residency program director at Methodist. Dr. Barnett participated in numerous professional organizations throughout his long career and retired from clinical medicine in January 2003. Dr. Barnett was considered a tough and inspiring teacher with a colorful style and his influence is still felt by many. He trained hundreds of residents, many of whom still practice in the state of Texas. The Texas chapter of the American College of Physicians honored Dr. Barnett as a laureate for 2003 and the national chapter made him a laureate in 2007. He was predeceased by his daughter, Sheryl Mercer, in 1997. Survivors include Martha Barnett of Dallas; sons Jeffrey Barnett of Madrid, Spain, and Gary Barnett of Cedar Hill; son-in-law Joaquín Fonollá of Madrid; daughter-in-law Jean Barnett and beloved grandchildren Kevin and Lauren, all of Cedar Hill; Stormy, Tiny and Tripod. The family extends special thanks to Leigh, to Juanita and to Doris, whose long-time collaborations and support have been extraordinary. Funeral services will be held at noon Feb. 23, 2008, at Boze-Mitchell-McKibbin Funeral Home in Waxahachie. A memorial service for Dr. Barnett will also be held at Methodist Central in Oak Cliff at noon March 6, 2008. In lieu of flowers, Mox’s family would welcome donations made to the Jack A.
