Johann Friedrich Schultze

Johann Friedrich Schultze (born 3 October 1911 in Neukölln) was a German mathematician and cryptographer.

During the late 1930s, Schultz worked as a scientific assistant to Erich Hüttenhain in a new mathematical research department, that would eventually be called Section IVc of Cipher Department of the High Command of the Wehrmacht (OKW/Chi) in World War II.

Schultze's father was Friedrich Schultze and his mother was Hedwig Schultze, née Urban.

In April 1930, Schultze passed the school-leaving examination.

In 1939, Schultze was promoted with a Dr Phil with a doctoral dissertation titled: About unsteady fluid movements around predetermined profile (German:Über unstetige Flüssigkeitsbewegungen um vorgegebene Profile), achieving a rerum naturalium at Humboldt University of Berlin. His doctoral advisor was Alfred Klose, the astronomer and astrophysicst and Ludwig Bieberbach, the mathematician and National Socialist.

From 1 November 1938 to 30 September 1943, Schultze worked as a research assistant at the Institute of Applied Mathematics, at the Humboldt University of Berlin.
