On the centenary of her birth, Charlotte Salomon, who died in Auschwitz in 1943, is having the first-ever showing of the entirety of her ambitious magnum opus: a set of over 800 gouache paintings accompanied by writings and musical cues. Creating the series “Life? Or Theatre? A Play With Music” was a way for the artist to cope with her family history of mental illness while living in hiding in France. The works are colored both by her tragic family history—her namesake aunt, mother, and grandmother all committed suicide—and the evils of the Nazi regime.
