In "Escape from Which Island?," he's credited as "August Scharfenheimer" with only one "f" when there's supposed to be two.
He speaks with a German accent which implies that he is originally from a German-speaking country.
Like Randolph Brackenbrown and Samuel Summerbottom, his last name appears original and made up. However, some German surnames have similarly ended with "heimer,"[3][4] which comes from the German word "heim," or "home" in English. Additionally, "scharff" comes from "scharff," or "sharp" in English. Based on this, his last name has Germanic origins, which gives more implications that he's from a German-speaking country, and his last name means "sharp home."
