Athena, about halfway between Pendleton, Oregon, and Walla Walla, Washington, was originally called Centerville. However, confusion about the name sometimes arose because Oregon had another Centerville, in Washington County, and the state of Washington had a Centerville, in Klickitat County. In 1889, local government officials asked the Centerville school principal, D. W. Jarvis, to recommend a different name. He chose Athena after the Greek goddess, and they agreed. Centerville got its first post office on October 11, 1878. The first postmaster was William T. Cook. The post office name was changed to Athena on May 16, 1889. Nineteenth-century settlers of Scottish descent brought to Athena an interest in the customs and music of Scotland. Before World War I, Athena had a Caledonian Society that held an annual picnic featuring Scottish dancing and bagpipes. Weston-McEwen High School in Athena revived the tradition in the 1950s when it organized a Scots dance group and a pipe band. The band has since performed at many venues in the United States and has traveled to Scotland and England to play.
