Charles Arnoldi is a prominent American abstract artist renowned for his dynamic and colorful compositions that seamlessly blend painting, sculpture, and printmaking.

Born in Dayton, Ohio, in 1946, Arnoldi moved to California at the age of 18, where he briefly attended art schools before choosing to forge his own creative path. His work often incorporates natural materials like branches and plywood, creating intricate assemblages that evoke both architectural forms and elements of the natural world. Arnoldi's bold, geometric abstractions, characterized by hard-edged shapes and fluid, lyrical lines, have established him as a significant figure in the contemporary art scene since the 1970s.

Throughout his career, Arnoldi has consistently pushed the boundaries of media and form, experimenting with diverse techniques and materials. His works range from early stick constructions to vibrant, large-scale paintings that explore the interplay of color, shape, and space. Arnoldi's art is included in the collections of the Whitney Museum, Museum of Modern Art in New York, the Los Angeles County Museum of Art, the Smithsonian, and the Guggenheim in Bilbao, amongst others. His ability to merge the physicality of sculpture with the flatness of painting has earned him a reputation as a master of "post-minimal" abstraction, creating pieces that are both visually striking and intellectually engaging.
