Karl Heinrich Klaustermeyer (22 February 1914 – 21 April 1976) was a German Nazi Party official who served in the Gestapo, NSKK, and SA.

In 1965, he was found guilty of war crimes and sentenced to life in prison by the Bielefeld regional court.

One witness would later testify that, among other things: "I stood just a few meters away and had to watch Klaustermeyer shoot my mother, wife and my three-month-old child...."[1] On occasion, Klaustermeyer would ride a bike into the ghetto with an acquaintance, Josef Blösche, and shoot people at random.

Near the end of 1943, Klaustermeyer was tasked with excavating and burning the bodies of Jews who had been murdered earlier, as part of Sonderaktion 1005.

[1] After Germany's surrender, Klaustermeyer was detained by British occupation forces and sent to an internment camp.

The judge noted that the proven victims were killed entirely of his own volition and his "sheer lust for murder."

He said that Klaustermeyer, who maintained his innocence, had hated Jews his entire life and showed no signs of remorse.

According to Nazi-era reports, between April and December 1941 alone, more than 7000 Ghetto inmates had died from "bullet wounds" in the street, which means they were shot for no other reason other than that an SS or another German official walked past.

[4] Klaustermeyer was sentenced to nine life terms with hard labor and ordered to permanently forfeit his civil rights.
