Louis Persinger (11 February 1887 – 31 December 1966) was an American violinist and pianist.
Persinger trained at the Leipzig Conservatory where he studied with Hans Becker, before finishing with Eugène Ysaÿe in Brussels and studying with Jacques Thibaud in France for two summers. He served as leader of the Berlin Philharmonic orchestra and the Royal Opera Orchestra in Brussels before being appointed leader and assistant conductor of the San Francisco Symphony Orchestra in 1915 and succeeding Leopold Auer at the Juilliard School in New York in 1930.
He was best known as the teacher of great violinists Yehudi Menuhin, Ruggiero Ricci, Isaac Stern, Camilla Wicks, Almita Vamos, Fredell Lack, Guila Bustabo, Arnold Eidus, Donald Erickson, Zvi Zeitlin, Leonard Posner, Enrique Danowicz and Louise Behrend. He was also Ricci's piano accompanist for many recitals and recordings, and Menuhin's for his first few recordings.
