Heinrich Himmler

Reichsfuhrer-SS Heinrich Himmler was the commander of the Schutzstaffel (SS) in Nazi Germany under Adolf Hitler.

At some point during the 1930s, the Fifth Doctor met Himmler while pursuing across Berlin. (PROSE: The King of Terror)

In 1939, the Seventh Doctor met Himmler at a party rally in Nuremberg. Himmler was initially suspicious of the Doctor until he convinced him that he was a secret occult master. Himmler then told the Doctor about the Black Coven at Drachensberg. (PROSE: Timewyrm: Exodus)

In 1944, Himmler acquired the Scrying Glass from Colonel Otto Klein and began attempting to learn its secrets. (PROSE: The Shadow in the Glass)
