The Wikipedia article of the day for October 26, 2016 is Bud Dunn.
Bud Dunn (1918–2001) was a horse trainer who specialized in training and showing Tennessee Walking Horses. Born in 1918 on a farm in Scott County, Kentucky, he later moved to Florence, Alabama, where he owned and operated Bud Stables, a show horse training stable that produced twenty World Championships. He additionally trained and rode two horses who won the World Grand Championship at the Tennessee Walking Horse National Celebration, a national-level horse show held annually in or near Shelbyville, Tennessee. Dunn's first World Grand Championship came in 1992 with the bay stallion Dark Spirit's Rebel, and the second in 1999 with a son of that stallion, RPM. At the time of RPM's win, Dunn was 81 years old, making him the oldest winning rider on record. For his contributions, he was twice named Trainer of the Year, and was inducted into the Tennessee Walking Horse Hall of Fame and the Lauderdale County Sports Hall of Fame. Dunn's son Steve also became a successful horse trainer, winning two World Grand Championships.
