"Edgar Miller (1899–1993) arrived in Chicago in 1917, and over the next fifty years, established a successful career as a multi-hyphenate creative practitioner. He worked as an architect, artist, craftsperson, curator, designer, and illustrator during a particularly rich period that saw the ascendancy of modernism across the visual culture of the city."
