Alexander Aigner


Alexander Aigner was a full university professor for mathematics at the Karl Franzens University in Graz, Austria. During World War II he was part of a group of five mathematicians, which was recruited by the military cryptanalyst Wilhelm Fenner, and which included Ernst Witt, Georg Aumann, Oswald Teichmueller and Johann Friedrich Schultze, to form the backbone of the new mathematical research department in the late 1930s, which would eventually be called Section IVc of Cipher Department of the High Command of the Wehrmacht. . The group was led by the German professor of mathematics Wolfgang Franz.

Life

Alexander Aigner was the son of noted medical doctor :de:Oktavia Aigner-Rollett|Oktavia Aigner-Rollett and grandson of noted physiologist and histologist of Alexander Rollett. He studied mathematics and physics in at the University of Graz. In 1936, he was put forward by Dr. Karl Brauner for promotion to Dr. Phil, with Dr. Tonio Rella advising, with a thesis titled: Mathematical treatment of the hermit game in the plane and in space. About the possibility of in square bodies. He was offered a position as assistant at the 2nd Chair for Mathematics at Karl Franzens University. During World War II, he was recruited along with a number of other mathematicians to make up the backbone of a new cipher bureau for the German Army. He would eventually work at the mathematical research department IV/Section IVc of OKW/Chi under Erich Hüttenhain in the deciphering of complex foreign encryption systems. In 1947 he qualified as a professor at the Karl Franzens University in Graz, where he received an assistant position from :de:Georg Kantz|Georg Kantz. In 1957, he became an extraordinary professor and finally a full professor.
