Erich Zimmerman
Erich Zimmerman was a German General and loyal member of the Nazi Party. In 1938, he was cornered by the Teselecta in an office in the Reich Chancellery in Berlin; the robot assumed his shape and appearance before the terrified General's eyes. The Teselecta then miniaturised Zimmerman and transported him inside itself, where, upon discovering his identity and political affiliation, the crew abandoned him to be killed by the antibodies.
The Teselecta, disguised as Zimmerman, made its way to the office of Adolf Hitler, where it attempted to punish him. The Fuhrer was saved by the sudden - and accidental - arrival of the TARDIS through his office wall. (DW: Let's Kill Hitler)
Seeing as how the Teselecta had accidently arrived a few years earlier, having intended to arrive shortly before Hitler's death, Zimmerman presumably lived longer in the timeline originally.
