Bill Livingston has been an astronomer at the Kitt Peak Observatory in southern Arizona for his entire professional life (since Jan 1959). Originally he helped design and build instruments and telescopes. Later he became a solar observer and has spent a great deal of time on Kitt Peak, a fact which accounts for many of the pictures in this book. He participated in many solar eclipse expeditions which took him to Alaska, the South Pacific, Africa, Indonesia, India, and recently Turkey. He has traveled widely in Russia and China, but he hastens to add that his best sightings of atmospheric phenomena were from his backyard in Tucson.
