Hermann Föttinger (9 February 1877 in Nuremberg – 28 April 1945 in Berlin) was a German engineer and inventor.
From 1895 to 1899 Hermann Föttinger studied electrical engineering at the Technical University of Munich.
In 1909 he obtained a position at the Technische Hochschule in Danzig where he started the institute for fluid dynamics technology.
Föttinger laid the basis of the fluid dynamics from Euler over Rankine and Hermann von Helmholtz to its current uses in the boundary layer of airplane wings and propulsion theory.
Together with Franz Kruckenberg he started the Flugbahn-Gesellschaft mbH to develop the Schienenzeppelins (railroad cars).
