Major Karl-Erich Kuhlenthal
Major Karl-Erich Kuhlenthal was a German spy during World War II.
He was one of the most senior Abwehr agents in Spain.
In 1943 Kuhlenthal went about attempting to find important British documents found on the body of Captain William Martin, who had been washed up in Spain after a possible plane crash.
In fact, the documents were false and the body that of Glyndwr Michael, a homeless Welsh man.
These were part of Operation Mincemeat, a plan to convince the Germans that the Allies planned to invade Greece and Sardinia instead of Sicily.
It is not certain if Kuhlenthal was convinced by the documents, some of his relatives being Jewish, but he passed the documents onto his superiors who "swallowed mincemeat whole."
