Katja Andy (born Käthe Aschaffenburg; 23 May 1907 – 30 December 2013) was a German-American classical pianist and piano professor.
Her parents were musical patrons and used to accommodate touring soloists of the local philharmonic concerts at the family home, including stars like Adolf Busch, Joseph Szigeti, Eugen d’Albert, and Walter Gieseking.
In Bach's concertos for multiple keyboards, her fellow student and lifelong friend Grete Sultan joined Fischer and Aschaffenburg.
[citation needed] This promising start of a concert career was cut short by Adolf Hitler's rise to power in January 1933.
When the Nazi regime told her she was not allowed to teach "Aryan" students anymore, she fled Germany to Paris in April 1933, taking the name Katja Andy, which she used thereafter.
In 1958, she became friends with Austrian pianist Alfred Brendel, himself a student of Edwin Fischer, whom she met at the festival of Lucerne, Switzerland.
