"Saul David Alinsky" was an American community organizer, and writer. He is generally considered to be the founder of modern community organizing. He is often noted for his book Rules for Radicals.
In the course of nearly four decades of political organizing, Alinsky received much criticism, but also gained praise from many public figures. His organizing skills were focused on improving the living conditions of poor communities across North America. In the 1950s, he began turning his attention to improving conditions in the African-American ghettos, beginning with Chicago's and later traveling to other ghettos in California, Michigan, New York City, and a dozen other "trouble spots".
His ideas were adapted in the 1960s by some US college students and other young Counterculture of the 1960s/counterculture-era organizers, who used them as part of their strategies for organizing on campus and beyond. Time (magazine)/Time magazine once wrote that "American democracy is being altered by Alinsky's ideas," and conservative author William F. Buckley said he was "very close to being an organizational genius."More Saul Alinsky on Wikipedia.
