Science for the People (SftP), the most important radical science movement in US history, arose in 1969 out of the anti-war movement and lasted until 1989. With a Marxist analysis and non-hierarchical governing structure, SftP tackled, among many issues: militarization of scientific research, corporate control of research agenda, political implications of sociobiology and other scientific theories, environmental consequences of energy policy, inequalities in health care, etc. Its members opposed racism, sexism, and classism in science and above all sought to mobilize people working in scientific fields to become active in agitating for science, technology, and medicine that would serve social needs.
