Who was Otto Blumenthal?

Ludwig Otto Blumenthal 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 ghetto Theresienstadt in Bohemia, 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,
