Anti-German sentiment
Anti-German sentiment contributed to passage of a 1919 state law that enforced teaching in English. By law, "No person, individually or as a teacher, shall, in any private, denominational, parochial or public school, teach any subject to any person in any language than the English language." Robert Meyer was found to violate this law because he taught German. He was taken to court by the State of Nebraska. Although his appeal to the Nebraska Supreme Court failed, the U.S. Supreme Court in "Meyer v. Nebraska" determined that Meyer had the right to teach the German language as a subject, and to teach it in German.
