Telephone operator. Woman working in a telephone exchange in Paris, 1890. Connections between early telephones were made manually by the operators. Technological improvements in this Parisian exchange meant that people, for the first time, provided a number rather than a name, and they were passed between fewer people before being connected. This innovation was known as Poste assis. Taken from Physique Populaire, 1891.
