John Muir College is one of the six undergraduate colleges at the University of California, San Diego (UCSD). The college is named after John Muir, the environmentalist and founder of the Sierra Club. It has a humanitarian emphasis focused on the "spirit of self-sufficiency and individual choice". Its general education requirements are more loosely structured than those of the other colleges, with an emphasis on "sequences" and individual study.
The college opened in 1967, at the height of the American environmentalist movement triggered in part by Rachel Carson's book Silent Spring. John Muir College describes itself as the "Heart of UCSD" and boasts a strong and distinct character after forty years of existence.
