With customary vivacity and a fine sense of irony, Krull portrays her subject as a genial family man who suffered reverse after reverse thanks to a bad combination of deep-seated optimism and zero business sense—but pulled through when his love of storytelling and sense of audience at last led to a novel that instantly became (she notes) the Harry Potter of its day. She does mention Baum’s anti-American Indian screeds, but in general tells a brisk, admiring tale that mirrors the tone of his talespinning—aptly illustrated by Hawkes’s scenes of a frail, dapper looking gent, generally sporting a smile beneath a bushy mustache and gazing abstractedly into the distance. An admirable companion to Krull’s Boy on Fairfield Street: How Ted Geisel Grew Up To Become Dr. Seuss (2004), this profile not only provides a similarly illuminating peek beneath the authorial curtain, but leaves readers understanding just how groundbreaking The Wonderful Wizard of Oz was, as an adventure story with both a female protagonist and no overwhelming Moral Lesson.
