Mark di Suvero is an American Abstract Expressionist sculptor who creates distinctive, monumental works that embrace the scale of the landscapes and urban centers in which they are displayed. His early works were large outdoor pieces that incorporated industrial materials such as railroad ties, tires, scrap metal, and structural steel. His exploration of materials has transformed over time into a focus on I-beams and heavy gauge metal. Many of the pieces contain sections that are allowed to swing and rotate, giving the overall forms a considerable degree of motion. Di Suvero prides himself on his hands-on approach to the fabrication and installation of his work. He is also credited with founding the Socrates Sculpture Park in Queens, NY.
