''Robber Baron is a welcome addition to the surprisingly small shelf of full-length biographies of Chicago's storied entrepreneurs and can be read for profit by anyone intrigued by one of the most notorious of the men to have built the material foundations on which the city's prosperity has come to rest.'' Chicago Tribune ''A fascinating window into the workings of laissez-faire capitalism. Yerkes, one of the most notorious self-made men of nineteenth-century America, embodied the drive, avarice, and unscrupulousness of his age-- taking each to its limits... Franch's narrative of the ups and down of Yerkes's career is well written and has considerable dramatic tension.'' Enterprise & Society ''A superb biography: The research is thorough, the prose is clear, the narrative is compelling and the judgments are fair.'' Wall Street Journal
