John Dillinger
While a lot of people have heard of John Dillinger in the past, the best adjective for him is “infamous.” How else are you meant to describe such a high-profile bank robber? However, you might be surprised to hear that he was a member of the U.S. Navy fire brigade before he started his criminal career.
Buster Keaton
It is no secret that war tends to leave marks on the people who witnessed it. Buster Keaton has gone through it as well. He fought the Germans in France during the Great War and damaged his hearing. It is pretty neat that he made a name for himself in silent films after serving in the 40th Infantry Division.
