Johanna (Hanna) Hammarström was a Swedish inventor who was born on September 4, 1829 and died on November 27, 1914. Although telephones had already been invented, no one in Sweden could manufacture the copper wires needed to function telephones. She became the first person in Sweden to manufacture telephone wires and ran her own business in the production of these wires.
