This picture book biography of Charles Darwin combines a narrative of his life with selections from his own writings and hand-tinted woodcut illustrations. Darwin’s years are chronicled from boyhood to his death, with a focus on his adult scientific exploration and discovery. Throughout, notes from Darwin’s autobiography and notebooks, as well as other writings, give a glimpse of his personal passions and doubts. From his childhood activities of collecting and chemistry experiments, to his lack of interest in conventional academic study, to his travels aboard the Beagle , Darwin emerges as a thoughtful and introspective individual. He is simultaneously unable to deny his belief in his innovative theories and concerned that others might respond negatively to them. An author’s note includes a complete list of sources quoted. (Ages 8–12)
