Dallin studied in Boston and in Paris and then returned to Boston to teach sculpture at the Massachusetts School of Art. As a boy Dallin had lived among Indians, and his portrayals of them were in a naturalistic mode, devoid of the melodrama often associated with this subject by some of his contemporaries. Among Dallin's most notable works are “The Signal of Peace” (1890; Lincoln Park, Chicago), “The Medicine Man” (1899; Fairmount Park, Philadelphia), and “Sir Isaac Newton” (Library of Congress, Washington, D.C.).
