Hammering Man
Hammering Man is a series of monumental kinetic sculptures created by American artist Jonathan Borofsky, featuring large-scale painted steel silhouettes of an anonymous worker whose motorized arm swings a hammer up and down in perpetual motion.[1][2]
The sculptures, first developed in the early 1980s, symbolize the universal laborer—encompassing craftsmen, miners, farmers, and modern professionals—and celebrate human effort through their tireless, mechanical repetition.[3][1]
Installations exist worldwide, with the largest at 72 feet tall in Seoul, South Korea, followed by a 70-foot version in Frankfurt, Germany, mounted on the Messeturm building since 1990.[3][1]
Other prominent examples include a 48-foot sculpture outside the Seattle Art Museum, installed in 1991 and operating at four cycles per minute, as well as versions in Basel, Switzerland (13.5 meters tall since 1989), and Los Angeles.[2][4][3]
Borofsky's design, often commissioned for public and commercial spaces, uses simple two-dimensional forms and silent motors to evoke both industrial rhythm and the dignity of work, without overt political messaging.[1][5]
