Apart from art classes taken in Chicago during the 1950s, Quinn never attended art school; nonetheless, taking advantage of books, museums, and amassing a sizable collection, he managed to give himself an effective education in the language of modern art. By the early 1980s, his work had caught the eyes of various gallery owners and was exhibited internationally, in Mexico City, Los Angeles, New York City, and Paris. His work is now represented in both public and private collections throughout the world.
