In Gideon Lincecum's lifetime the United States expanded from fifteen to thirty-eight states—and Lincecum moved always with or ahead of that expansion. Possessed of a driving intellectual curiosity undeterred by lack of formal education, Lincecum examined all he confronted. He learned from Indians, he read widely, and he corresponded with the great minds of his day. In the process he became many things: physician, musician, botanist, entomologist, ornithologist, and translator of Indian dialects. His collection of information and specimens in the field of natural science was used by leading authorities. From his voluminous letters, Mrs. Burkhalter has constructed a picture of a "remarkable and delightful American who deserves a place in the history of this country."
