Erwin Kreuz – Wikipedia

Erwin Kreuz (born 1927) was a West German tourist to the United States who achieved international celebrity status in the late 1970s for mistaking the city of Bangor, Maine for San Francisco, California.The incident made Kreuz a folkloric figure whose story continues to be told in various media as an iconic (if extreme) example of an airline traveler not reaching their intended destination.
