Grade 4-8-This biography relates the main events in Harvey's life (1578-1657), provides a brief explanation of early theories of circulation, and makes clear the importance of his discovery. Written in a strong, terse style, the narrative discusses both what is known to have happened to the man, and what may have occurred according to other accounts of the time. Quotes-many from Geoffrey Keynes's The Life of William Harvey (Oxford, 1966; o.p.), Harvey himself, and his contemporaries-include explanations of unfamiliar usage. Black-and-white reproductions of portraits, medical diagrams, and bookplates are scattered throughout. G. Whitteridge's William Harvey and the Circulation of the Blood (Elsevier, 1970; o.p.) devotes a chapter to the man's life and the rest of the book to his theories and writings.
