Oersted, Hans Christian
Hans Christian Oersted (Ørsted in Danish) was born on 14 August 1777 and he was a Danish physicist and chemist who discovered that electric currents create magnetic fields, which was the first connection found between electricity and magnetism.

This relationship is now known as Ohm's law.
