Physicist, born in Königsberg, Prussia (now Kaliningrad, Russia). He studied at Königsberg and became professor of mathematics at Clausthal (1897), and professor of physics at Aachen (1900) and Munich (1906). With Felix Klein he developed the theory of the gyroscope. He researched into a variety of problems, including X-ray and electron diffraction, and radio waves. He is best known for his work on the Bohr atomic model, and the notion of elliptical rather than circular electron orbits.

Arnold Johannes Wilhelm Sommerfeld (December 5, 1868 in Königsberg, East Prussia – April 26, 1951 in Munich, Germany) was a German physicist who introduced the fine-structure constant in 1919.
Arnold Sommerfeld studied mathematics and physical sciences at University of Königsberg.
Sommerfeld was a great theoretician, and besides his invaluable contributions to the quantum theory, he worked in other fields of physics, such as the classical theory of electromagnetism.
