Oberst Brandt
From Tardis Wiki, the free Doctor Who reference
Oberst Brandt was a Colonel in the German Army. He welcomed the Sixth Doctor to Germany. He thought that Harry Houdini had perfected the Estrati technology and that's why he wanted it. He forced Peri to show him her trick but she confessed the truth. [statement unclear] (AUDIO: Harry Houdini's War)
