Richard "Cactus" Pryor (born January 7, 1923) is considered a legend in Texas broadcasting. A native Austinite, Pryor has been a fixture in Texas broadcasting and entertainment since 1944. He received his nickname after the old Cactus Theater on Congress Avenue in Austin, Texas, which was run by his father, Skinny Pryor. Cactus has also appeared in two movies, Hellfighters and The Green Berets with John Wayne. He is the author of a 1995 collection of some 40 essays entitled "Playback". He currently regales audiences on Austin radio with a daily 2-minute trip down memory lane, reminiscing about places and people from his past. Many of those of whom he speaks are long-gone. Pryor is one of the first people to have heard of the assassination of President John F. Kennedy, having been at the ranch of then-vice president Lyndon Baines Johnson at the time. His broadcasting sign-off consists of a series of words, "thermostrockamortimer". The spelling and meaning of such are up to speculation, though Cactus has stated, "The phrase is in the Bible; if you don't find it, keep reading."
