The First Switchboard
THE FIRST SWITCHBOARD
The first telephone switchboard was installed in New Haven, Connecticut, in 1878. Operated manually by teenage boys at first, the switchboards connected many telephones through one or two exchanges in large cities. Within a few years, women replaced the boys as operators, as they were considered to be more polite to the callers.
