Tehching Hsieh, a master of long duration performance art. Below is a description of one of his performances (according to Marina Abramovich)
Tehching Hsieh, One Year Performance 1978–1979 (Cage Piece)
In this performance, which lasted from September 29, 1978 through September 30, 1979, the artist locked himself in a 11′6″ × 9′ × 8’ wooden cage, furnished only with a wash basin, lights, a pail,and a single bed. During the year, he was not allowed to talk, to read, to write, or to listen to radio and TV. A lawyer, Robert Projansky, notarized the entire process and made sure the artist never left the cage during that one year. A friend came daily to deliver food, remove the artist’s waste, and take a single photograph to document the project. In addition, this performance was open to be viewed once or twice a month from 11am to 5pm.
