I thought Hitler got his mustache from Charlie Chaplin.
It was a perfect fit in “The Great Dictator” (1940).
“it is doubtful that he adopted it because of Charlie Chaplin. One simple reason that Charlie Chaplin is probably not the inspiration for Hitler’s mustache is that self-consciously adopting the mustache of a silent film comedian would have invited people to ridicule Hitler, which would have stopped his rise to power in its tracks.
“Instead, most of the evidence suggests that Hitler adopted his mustache for more utilitarian reasons either because it was easier to keep hygienic than other German mustache style, because he was forced to cut his old mustache while he was in the military, or because he simply wanted a trademark that would help him stand out as the leader he envisioned himself to be.

LOL
Someone who’s studied German history especially relating to WWII mentioned that Hitler actually decided to use that particular style of mustache to set him apart from the other politicians. He wanted to stand out and as he wasn’t an impressively sized man he needed to look different using another tact.
