Ralph Nader (; born February 27, 1934) is an American political activist, author, lecturer, attorney, and presidential candidate, noted for his involvement in consumer protection, environmentalism and government reform causes.
The son of Lebanese immigrants to the United States, Nader was educated at Princeton and Harvard and first came to prominence in 1965 with the publication of the bestselling book Unsafe at Any Speed, a highly influential critique of the safety record of American automobile manufacturers. Following the publication of Unsafe at Any Speed, Nader led a group of volunteer law students—dubbed “Nader’s Raiders”—in an investigation of the Federal Trade Commission, leading directly to that agency’s overhaul and reform. In the 1970s, Nader leveraged his growing popularity to establish a number of advocacy and watchdog groups including the Public Interest Research Group, the Center for Auto Safety, and Public Citizen. Two of Nader’s most notable targets were the Chevy Corvair and the Ford Pinto.Nader’s activism has been directly credited with the passage of several landmark pieces of American consumer protection legislation including the Clean Water Act, the Freedom of Information Act, the Consumer Product Safety Act, the Foreign Corrupt Practices Act, the Whistleblower Protection Act, and the National Traffic and Motor Vehicle Safety Act. He has been repeatedly named to lists of the “100 Most Influential Americans”, including those published by Life, Time, and The Atlantic.
Nader made four bids to become President of the United States, running with the Green Party in 1996 and 2000 and as an independent in 2004 and 2008. In each campaign, Nader said he sought to highlight under-reported issues and a perceived need for electoral reform. He received nearly 3 million votes during his 2000 candidacy, but also stirred controversy over allegations that his campaign helped Republican candidate George W. Bush win a close election against Democratic candidate Al Gore.
A two-time Nieman Fellow, Nader is the author or co-author of more than two dozen books, and was the subject of a documentary film on his life and work, An Unreasonable Man, which debuted at the 2006 Sundance Film Festival.
