Final answer:
Max Fleischer, an animator and cartoon producer, was mostly based in New York City, which emerged as a critical center for artists and intellectuals during and after World War I.
Step-by-step explanation:
Max Fleischer, best known for his work as an animator and cartoon producer, was mostly based out of New York City. This city became especially significant in the arts during and after World War I, transforming into a hotspot for creative minds. Historical context tells us that like Zurich, New York City was a sanctuary for writers and artists fleeing from the devastation of World War I. Figures such as Marcel Duchamp, Francis Picabia, and Man Ray gathered in New York City in 1915, which led to it becoming a center for bold anti-art movements. Furthermore, during the tumultuous times around World War II, many European artists, writers, and intellectuals sought refuge in the United States, with New York succeeding Paris as the hub of the art world.
