Adolf Georg Wilhelm Busch (1891–1952) was a German–Swiss violinist, conductor, and composer.
In 1927, with the rise of Adolf Hitler, Busch decided he could not in good conscience stay in Germany, so he emigrated to Basel, Switzerland. Busch was not Jewish and was popular in Germany, but firmly opposed Nazism from the beginning. On 1 April 1933, he repudiated Germany altogether and in 1938, he boycotted Italy. As the Nazis tried to convince him to return to Germany, he declared that he would "return with joy on the day that Hitler, Goebbels und Göring are publicly hanged."
He was the son of the luthier Wilhelm Busch; brother of the conductor Fritz Busch, the cellist Hermann Busch, the pianist Heinrich Busch and the actor Willi Busch, and father in law of the pianist Rudolf Serkin.
