Leo Weisgerber
Johann Leo Weisgerber (25 February 1899,
Metz – 8 August 1985,
Bonn) was a
Lorraine-born
German linguist who also specialized in
Celtic linguistics. He developed the "organicist" or "
relativist" theory that different languages produce different experiences. He was the son of a village teacher who served as a young man in the German army in Flanders, so could not return to his home city. During
World War II his
pan-Celticist ideology was co-opted to support the German war effort, as did pro-Polish and pro-Czech ideology on the side of the allies.
