Alain L. Locke, in his famous 1925 anthology The New Negro, declared that 'the pulse of the Negro world has begun to beat in Harlem'. The first biography of this extraordinarily gifted philosopher and writer, Alain L. Locke narrates the untold story of his profound impact on twentieth-century America's cultural and intellectual life. The heart of this narrative illuminates Locke's heady years in 1920s New York City and his forty-year career at Howard University, where he helped spearhead the adult education movement of the 1930s and wrote on topics ranging from the philosophy of value to the theory of democracy.
