Max Weber was accomplished as a sculptor as well as a painter. He pioneered the first non-objective abstract sculpture ever made in the United States with pieces such as Spiral Rhythm. Yet sculpture remained rare in Weber’s work – only about thirty examples are known, and half of those were executed in 1915, the year he made Spiral Rhythm. That same year Arthur D. Chapman photographed Weber in a contemplative pose, holding Spiral Rhythm almost as if it were a newborn child. Chapman’s platinum print is a testament to Weber’s engagement with this new, three-dimensional exploration of abstraction. Years later, Weber wrote that he had taken up sculpture “to work out problems of form.” Spiral Rhythm remained a favorite. Weber eventually had it cast in bronze at a much larger scale than the original plaster. An example of the bronze version is in the collection of the Hirschhorn Museum, Washington, D.C.
