The brand Dalli got its name by chance:
“Dalli! Dalli!“, a luggage carrier of a Polish train station shoutet at his colleage, who suddenly started working faster.
Franz Wirtz, owner of Mäurer + Wirtz, was watching this scene. He registered the word, which means “fast” in Polish, as a trademark with the Imperial Patent Office in 1899.
