Award-winning author, Thom Hatch presents the definitive biography of George Bird Grinnell (1849-1938), who was recognized in his time as "The Father of American Conservation." This book chronicles not only Grinnell's life, but also offers a history of his accomplishments in saving the wildlife and natural resources of this country. A remarkable man, Grinnell was known as a model of intellectual diversity, integrity, and professional dedication. He was a daring adventurer and explorer; crusading magazine publisher and editor (Forest and Stream, now Field and Stream); prolific author; accomplished outdoorsman; notable paleontologist, ethnologist, ornithologist, and anthropologist; presidential advisor; advocate for Native Americans; and this country's first environmental activist, whose contributions in that arena are unparalleled in American history.
