Armgaard Karl Graves was a spy who worked for the British MI5 during World War I. Here's a summary of what I found about him:
- Double Agent: Graves was a mole planted inside the German Imperial Navy's intelligence branch [Wikipedia]. He fed British intelligence crucial information before and during the war [Wikipedia].
- Caught: The Germans eventually discovered him and fired him, calling him a "double-dyed rascal" [Wikipedia].
- Later Life: In 1934, after the war, he was sentenced to prison in the US for theft [Wikipedia]. There are reports that the US government intervened to prevent his deportation back to Germany because of fears of Nazi persecution [Wikipedia]. It is believed he died in the United States [Wikipedia].
- Legacy: Though not a household name, Graves played a role in Allied intelligence efforts during WWI. You can find his book, "The Secrets of the German War Office", on Project Gutenberg [Project Gutenberg]
