Which prominent Chicago artist is associated with the creation of abstract sculptures?

The association of abstract sculptures in the context of Chicago is most accurately linked to Alexander Calder. Calder is renowned for his innovative contributions to sculpture, particularly his development of mobile sculptures, which are abstract and often kinetic in nature. He is famously known for works such as the large-scale mobile created for the Smithsonian and the monumental stabile sculptures in various public installations, many of which can be found in urban environments, including Chicago.

While other artists mentioned have their unique signatures—such as Marc Chagall with his colorful stained glass, Pablo Picasso with his cubist painting and sculpture styles, and Frank Lloyd Wright primarily known for his architectural genius—none have the same prominent reputation for abstract sculpture as Calder. His impact on the field of sculpture, especially in an urban context like Chicago, solidifies his status as a pivotal figure within abstract art in the city.
