Franz Harress

Franz Harress (died circa 1915) was a mathematician and contemporary of Albert Einstein and is best known for his experiment on the propagation of light in a rotating glass device. This experiment sparked an argument between Albert Einstein and Paul Harzer related to the theory of Special Relativity.[1] Harress was a student of Professor Otto Julius Heinrich Knopf at Friedrich-Schiller-Universität Jena in 1912.[2] His dissertation was "Die Geschwindigkeit des Lichtes in bewegten Körpern" ("The speed of light in moving bodies").[3] His work on the Sagnac effect was analyzed by Max von Laue in his 1920 paper "On the Experiment of F. Harress."[4]
