Ludwig Otto Blumenthal (20 July 1876 – 12 November 1944) was a German mathematician and professor at RWTH Aachen University.

He was born in Frankfurt, Prussia. A student of David Hilbert, Blumenthal was an editor of Mathematische Annalen.

Blumenthal, who was of Jewish background, emigrated from the Nazis to the Netherlands, lived in Utrecht and was deported via Westerbork to the concentration camp, Theresienstadt in Bohemia (now Czech Republic), where he died.

In 1913, Blumenthal made a fundamental, though often overlooked, contribution to aerodynamics by building on Joukowsky's work to extract the complex transformation that carries the latter's name [1], making it an example of Stigler's Law.
