Paul Alfred Biefeld ( born March 22, 1867 in Jöhstadt, † June 21, 1943 in Granville, Ohio ) was a German astronomer and physicist.

Biefeld emigrated in 1881 for the first time in the United States. He received in 1894 from the University of Wisconsin -Madison with a Bachelor of Science in Electrical Engineering. Then took Biefeld for three years at the place of Conrector at the High School of Appleton, Wisconsin. From 1899 to 1900 he worked as a laboratory assistant to Professor HF Weber at the ETH Zurich, where he met Albert Einstein. In 1900 he received a PhD degree at the University of Zurich and married on April 11, Emma wad of Frankfurt am Main.

From 1900 to 1906 Biefeld was professor of mathematics, physics and electrical engineering at the Technical Hildburghausen. 1906 emigrated Biefeld finally to the United States. He settled in Ohio, where he taught until 1911, first as a professor at the University of Akron physics and astronomy. In 1911 he moved to Granville, Ohio, and was until 1936 a professor of astronomy at Denison University.

He also led in 1923 his protégé Thomas Townsend Brown to continue some basic research with X-ray tubes, which he had begun in 1921 experimentally. The findings in this respect have been known as Biefeld Brown effect. Biefeld also headed the Warner and Swasey Observatory in East Cleveland, Ohio, for which Brown also worked from 1926.
