Ralph Nader has spent a lifetime fighting on behalf of ordinary people, and few Americans have the respect and prestige that he commands. Life magazine ranks him as one of the country's most influential Americans of the twentieth century. Founder of Public Citizen, he is a long-time advocate for consumer safety and workers' rights. He rose to fame in the 1960s when he took on General Motors and its unsafe Corvair car. His 1965 book Unsafe At Any Speed not only created a sensation but was instrumental in the enactment of the Motor Vehicle Safety Act. He helped create the Environmental Protection Agency. He has exposed the misdeeds of the corporate sector as well as of the political system. He is perhaps best known for Nader's Raiders and for sparking debate on issues ranging from the Corvair to the Dalkon Shield. In recent years he has led the struggles around NAFTA, the WTO and corporate welfare. In 1996 he was the Green Party presidential candidate, and in 2000 he is their candidate again.
