Archival Overview
Epoch-making Danish physicist and chemist who discovered electromagnetism in 1820, isolated aluminum, and founded the Technical University of Denmark (DTU).
Biographical Record
Hans Christian Ørsted was born on August 14, 1777, in Rudkøbing on the island of Langeland. Educated in pharmacy and philosophy at the University of Copenhagen, he was deeply inspired by Immanuel Kant's view of the unity of fundamental forces in nature.
During a university lecture on April 21, 1820, Ørsted noticed that an electric current from a galvanic battery deflected a magnetic compass needle, establishing for the first time the direct connection between electricity and magnetism. In 1825, he made another monumental breakthrough by becoming the first person to isolate metallic aluminum. He founded the Polytechnic College (now DTU) and the Society for the Dissemination of Natural Science, and the CGS unit of magnetic field strength (oersted) honors his legacy.
