Benjamin Lee Whorf was an American linguist and fire prevention engineer. Whorf is widely known as an advocate for the idea that differences between the structures of different languages shape how their speakers perceive and conceptualize the world.

The idea, however, follows from post-Hegelian 19th century philosophy, especially from Wilhelm von Humboldt; and from Wilhelm Wundt's Völkerpsychologie.
