Jeremy Adelman's detailed and illuminating biography of Albert Hirschman in Worldly Philosopher: The Odyssey of Albert O. Hirschman is an excellent example of intellectual biography. Even more, it is a valuable contribution to our understanding of the development of social science theories and frameworks.
Born to a professional Jewish family in Berlin in 1915, Hirschman's life bracketed the most searing nightmares of the twentieth century. Hirschman was an anti-fascist activist as a teenager, leaving Berlin for France in 1933. He was an intellectual from the start, with curiosity and originality driving his quest for ideas and knowledge. But equally early he was an activist, with political convictions and allegiances that gave him the courage to resist fascism in every way he was able to. In France he pursued a doctorate in business (as the only French program he could enter), while continuing his anti-fascist activism.
