Carnegie Institution for Science - Geophysical Laboratory and Department of Terrestrial Magnetism

The Carnegie Institution for Science headquarters at 1530 P Street NW houses research units including the Geophysical Laboratory and the Department of Terrestrial Magnetism (DTM), the latter established in 1904. Scientists there performed early 20th-century experimental work in high-pressure physics, mineralogy, and geophysics that contributed to foundations of modern materials science. The laboratory's research influenced later developments in geology, planetary science, and engineering materials.
