Artist Dox Thrash (1893–1965), who attended night classes at the Art Institute of Chicago while working as an elevator operator, revolutionized printmaking in the 1930s by pioneering a completely new process called carborundum mezzotint – scraping away dark layers to reveal lighter grays and whites underneath. Faith Salie looks at the unique work of the African American artist.
