Ralph Nader

Ralph Nader is an American political activist, author, lecturer, and attorney noted for his involvement in consumer protection, environmentalism, and government reform causes, and a perennial presidential candidate. He became famous in the 1960s and 1970s for his book Unsafe at Any Speed, which criticized the automotive industry for its safety record and helped lead to the passage of the National Traffic and Motor Vehicle Safety Act in 1966.
The son of Lebanese immigrants to the United States, Nader attended Princeton University and Harvard Law School. Nader quickly developed an interest in vehicle designs that were hazardous and contributed to elevated levels of car accidents and fatalities. Published in 1965, Unsafe at Any Speed became a highly influential critique of the safety record of American automobile manufacturers focusing on General Motors' Corvair automobile in particular.
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.
