Charles Arnoldi is a painter, sculptor, and printmaker best known for his brightly colored, abstract paintings that incorporate wood. Born in Dayton, OH, Arnoldi attended Ventura College, the Art Center in Los Angeles, and the Chouinard Art Institute. Early on, he experimented with various painting techniques began integrating tree branches and twigs into his works. Arnoldi concentrated on his twig painting for nearly a decade, building different forms, including freestanding structures, sticks and string, and twigs attached in either densely packed or open shapes. In the late 1970s, he began casting his sculptures in bronze. In the 1980s, he experimented with bright colors, and created works on canvas, always preserving the elements of his wood pieces. He also started working with large plywood sheets, layering them together and using a chainsaw to cut shapes into the wood, and then painted it. He later used heavy blocks of wood, which were brightly painted and mounted on the wall. In the 1990s, Arnoldi created predominantly black and white paintings, characterized by free-flowing, organic shapes. Arnoldi has had numerous exhibitions throughout his career, at venues such as the Riko Mizuno Gallery in Los Angeles, the James Corcoran Gallery in Los Angeles, the Arts Club of Chicago, the Los Angeles County Museum of Art, the Brooklyn Museum, and the Museum of Contemporary Art, Los Angeles. His work is also part of the permanent collections of The Museum of Modern Art and The Metropolitan Museum of Art in New York, the Los Angeles County Museum of Art, the Smithsonian American Art Museum, and the Guggenheim in Bilbao.
