Tehching Hsieh is a Taiwanese performance artist who moved from Taiwan to the United States as a stowaway in 1974, living as an illegal immigrant until he was granted amnesty in 1988.
For One Year Performance 1980–1981, Hsieh rigorously punched a time clock every hour for 366 days from 11 April 1980 to 11 April 1981. The resulting installation consists of letters, statements, uniforms, photographs, punch clock and a time card. Between 1978 and 1986 Hsieh made five year-long performances, followed by a thirteen-year performance of making art but not publicly showing it.
