An American writer and naturalist, Thoreau spent two years in a cabin by Walden Pond to live simply. He refused to pay a tax he saw as supporting slavery and the war against Mexico, and spent a night in jail. His essay on civil disobedience inspired Gandhi, Martin Luther King and environmentalists.
