Dettmar Cramer (4 April 1925 – 17 September 2015) was a German football manager who led Bayern Munich to the 1975 and 1976 European Cups.

[1] Known as the "Football Professor",[2] because of his attention to detail and also as "Napoleon" because of his diminutive 1.61 meter stature, Cramer began his career at Viktoria Dortmund and Germania Wiesbaden.

The beginning of his managerial career led him to clubs such as Teutonia Lippstadt, VfL Geseke, FC Paderborn, and TuS Eving-Lindenhorst.

In order to strengthen its national team ahead of the Tokyo Olympic Games four years later, the Japan Football Association had the idea in 1960 of bringing in a foreign professional coach.

Through Cramer's coaching and leadership, and the efforts of his players, the Japan national team achieved a surprise upset over Argentina at the Tokyo Olympics.

His talents were highly regarded by FIFA (Federation Internationale de Football Association), which contracted him as a coach from 1967 to 1974 and sent him on a tour of the globe.

During his time in national team service, Cramer received numerous coaching offers from West German clubs in the Bundesliga, although he consistently turned them down.

For his international achievements, Cramer was awarded two honorary doctorates in addition to being presented with the Bundesverdienstkreuz (Federal Cross of Merit) in Germany.
