Jeffries Wyman (1814–74), a pioneer anthropologist of nineteenth-century America and one of its great comparative anatomists, was the Hersey Professor of Anatomy at Harvard University and, later, a trustee of the Peabody Museum and professor of American Archaeology and Ethnology.Wyman wrote the 59 letters in this volume to his only son Jeffie. Dating from 1866, when Jeffie was two, until Wyman’s death in 1874, when Jeffie was ten, the letters reveal a great scientist trying to instill in his son the concepts of acute observation and wonder. Wyman’s charming, quizzical drawings embellish the text, which will be appreciated by children and adults alike.
