John Wilson Ross (November 1863 – June 30, 1945) was a justice of the Supreme Court of Arizona from November 13, 1918 to January 6, 1919. At 8 weeks, Ross served the shortest tenure in the court's history while his brother, Henry D. Ross, served the longest.[1]
Ross was appointed by Governor George W. P. Hunt to replace outgoing Justice Alfred Franklin, who'd been defeated in the 1918 primary by Albert C. Baker.[2] [3] Franklin resigned before the end of his term to take a position as Collector of Internal Revenue for the Arizona–New Mexico District.[4]
Ross later served in the 9th Arizona State Legislature, representing Cochise County.[5] [6]
