Encyclopedia
Hanna Hammarström was a Swedish inventor and industrialist. She was the first Swede to develop telephone
vires. She manufactured the vires for the first Swedish telephone net. She also exported internationally.
Hanna Hammarström was the daughter of the silk- and cotton industrialist Per Hammarström (d. 1868) and Christina Holmberg. Her father wished for all his children to learn a profession, so she learned to manufacture various forms of ornaments. Though telephone vires were invented before her, the way to make them was not known in Sweden, and the Swedish telephone net was therefore defendant upon foreign manufacturers. Hanna Hammarström managed to develop telephone vires by herself, by the knowledge she learned by making ornaments out of metal strings. She started her own factory, and in 1883, she managed to take over the task to provide telephone vires to the Swedish telephone company from the foreign business companies. In her factory in Stockholm, she employed only women, whom she educated herself. In 1886, she was awarded first price for her invention at the great machine exhibition of Stockholm. She manufactured vires for several telephone factories. When the Swedish telephone net was organised over the country, it was with her vire. She upheld a monopoly position through the 1880s and 1890s.
