Michael Heizer an American land artist specializing in large-scale and site-specific sculptures. Working largely outside the confines of the traditional art spaces of galleries and museums, Heizer has redefined sculpture in terms of size, mass, gesture, and process.
A pioneer of 20th-century land art or Earthworks movement, he is widely recognized for sculptures and environmental structures made with earth-moving equipment, which he began creating in the American West in 1967. He currently lives and works in Hiko, Nevada and New York City.
1982 work at the former IBM Building in New York, Heizer sheared off the top of a large rock and cut grooves into the surface before setting it on supports hidden within a stainless steel structure. Designed as a fountain, the boulder appears to float over running water. He called it Levitated Mass, a title he would use again in future.
