Ralph Nader (/ˈneɪdər/; born February 27, 1934) is an American lawyer and political activist involved in consumer protection, environmentalism, and government reform causes. He is a perennial presidential candidate. His 1965 book Unsafe at Any Speed, which criticized the automotive industry for its safety record, 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. He 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' (GM's) Corvair automobile in particular.
