Ralph Nader is the pioneer of the modern American consumer movement, fulfilling the role in the late twentieth century that had been taken by muckraking journalists such as Upton Sinclair at the turn of the century. As a law student at Harvard in the late 1950s, Nader began to write about safety as a business issue, focusing especially on the automobile industry. He came to widespread public attention with a withering, and sometimes overstated, critique of American automobiles, Unsafe at Any Speed (1965). The resulting furor, including lawsuits and attempts by the car companies to discredit Nader, led to the first imposition of safety standards for cars. In the aftermath, consumer issues became a staple among political progressives in the 1960s. Nader attracted hundreds of young people—who became known as Nader’s Raiders—to work with him on consumer and public health issues . By the 1970s Nader moved into politics, becoming the Green Party’s perennial candidate.
