PDD Geoguessr #27: Duluth’s Former Telephone Exchanges
A year after Alexander Graham Bell invented the telephone, George W. Coy set up the first telephone exchange. Making a call to a specific phone required plugging the right cord into the right socket, and that required a person working out of an exchange building. Photos from the Minnesota Digital Library show the Duluth neighborhood exchanges that were operated by the Northwestern Bell Telephone Company in 1920. This post discusses the role of telephone exchanges as a source of employment for women in Duluth with a Geoguessr challenge that reveals what those telephone exchanges look like now.
