Florizel von Reuter (21 January 1890 – 10 May 1985) was an American-born violinist and composer, a child prodigy who went on to an adult career, mainly in Germany, as distinguished soloist and teacher of violin. He was also a psychic and medium and the author of several books on his alleged mediumistic communications with deceased musicians, and other works.
Born Florizel Reuter at Davenport, Iowa, U.S., he was the son of Jacob and Grace Reuter. His father was a musician and minor composer. Florizel had his first violin lessons with his mother. He showed extraordinary talent at a very young age, and went to London to study in 1899. He was taught by Max Bendix, Emile Sauret (who had also taught his father Jacob), César Thomson and Henri Marteau. In 1901 he graduated from the Geneva Conservatory, where there was a debate as to whether he should be allowed to graduate (presumably owing to his age). Several teachers refused to graduate any other pupils unless he was approved, and so the matter was settled.
His first professional concert was at La Chaux-de-Fonds in Switzerland in 1900. After giving 30 concerts in that country he began to tour in America, where he was introduced as a protégé of Joseph Joachim's. However, much of his early career was spent performing and teaching in Europe.
The name "von Reuter" was adopted in connection with his European career, as a significator of German aristocracy. In c 1916–1917 he became Director of the Zurich Music Academy. He retained his U.S. citizenship despite spending much of the following two decades in Europe. He published a useful introduction to the study and analysis of solo violin music, Führer durch die solo-Violinmusik, eine Skizze ihrer Entstehung und Entwicklung mit kritischer Betrachtung ihrer Hauptwerke (M. Hesse, 1926).
