Hitler is generally thought to have incorporated the toothbrush as a trademark of his appearance during the early meetings of the Nazi Party (formed in 1920). According to cultural historian Ron Rosenbaum, "there is no evidence (though some speculation)" that Hitler modeled his moustache on Charlie Chaplin's. [b] In 1923, Hitler's future publicist Ernst Hanfstaengl advised Hitler to lose the toothbrush, to which he replied, "If it is not the fashion now, it will be later because I wear it."
