Karl Heinrich Weise

[2] Karl-Heinrich Weise, the son of a middle school teacher,[2] studied mathematics, astronomy, and physics from 1928 to 1930 at Leipzig University.

[2][3] His doctoral dissertation, supervised by Robert König,[4][1] is entitled Beiträge zum Klassenproblem der quadratischen Differentialformen (Contributions to the class problem of quadratic differential forms)[1] and was published in 1935 in Mathematische Annalen.

Weise and Friedrich Bachmann had leading roles in reestablisting mathematics in Kiel during the postwar era.

[2] Bodo Schlender, a former doctoral student of Weise,[8] became the Kiel University's first professor of computer science.

Haken learned about Heinrich Heesch's contributions to the Four Color Problem and enthusiastically Weise's lectures on topology.

[2] Besides Haken and Schlender, Weise's other doctoral students include Andreas Dress, Wolfgang Gaschütz, and Wilhelm Klingenberg.

[4] Although Weise's fame rests upon his pioneering use of electronic computers in mathematics, most of his research dealt with differential geometry and topology.
