Older, obsolete theories suggested a connection of the name Brenner with the ancient tribe of the Breuni or the Gaulish chieftain Brennus, but since the pass name appears for the first time only in the 14th century, a more recent etymology is far more likely.[1] Prenner was originally the name of a nearby farm, which itself was named after its former owner. The farm of a certain Prennerius is mentioned in documents in 1288, a certain Chunradus Prenner de Mittenwalde is mentioned in 1299. The German word Prenner probably refers to somebody who uses slash-and-burn techniques for land clearing.
