Trivia Answer:
John Salmon 'Rip' Ford and his partner Michael Cronican
Before gaining fame as a Texas Ranger, Rip Ford had a brief career as a newspaper publisher, helping to found the Galveston News, and partnering with Cronican to form the Texas National Register of Austin in 1845. In 1846 the printing firm of Ford & Cronican was named public printer by the legislature.
After the death of his wife that same year, Ford signed on with Jack Hays' Texas Rangers for service in the Mexican War. He got the nickname 'Rip' while serving as adjutant. He would include the message, "Rest in Peace" when sending out death notifications. During battle conditions, he would shorten it to 'R.I.P.'
