Centennial History of the Carnegie Institution of Washington: Volume 2, The Department of Terrestrial Magnetism

The second of five Histories of the Carnegie Institution of Washington describes the work of the Department of Terrestrial Magnetism. Since its beginning in 1904, the department has witnessed an astonishingly broad range of research projects, from terrestrial magnetism, ionospheric physics and geochemistry to biophysics and planetary science. Many contemporary photographs illustrate some of the remarkable expeditions and instruments developed in the pursuit of scientific understanding.
