The Karl Weigl Foundation, founded in 1999, is dedicated to preserving the legacies of the Austrian-American exile composers Karl Weigl and Vally Weigl, and to encouraging rediscovery and appreciation of music suppressed by the Nazis.

In exile the Weigls often appeared together in recitals and
private musicales, performing four-hand piano works.

Karl Weigl (1881–1949) — important contributor to the ferment of musical styles in Vienna in the early twentieth century.

Vally Weigl (1894–1982) — pianist, teacher, composer, political activist, and pioneer of music therapy.

Along with other Jewish émigrés they contributed to the transformation and enrichment of American culture.
