Hammering Man is a series of monumental kinetic sculptures by Jonathan Borofsky. The two-dimensional painted steel sculptures were designed at different scales, were painted black, and depict a man with a motorized arm and hammer movement to symbolize workers throughout the world. They were structurally engineered by Leslie E. Robertson Associates.
Borofsky has stated that "The Hammering Man is a worker. The Hammering Man celebrates the worker. He or she is the village craftsman, the South African coal miner, the computer operator, the farmer or the aerospace worker-the people who produce the commodities on which we depend."
