Hanna's Early Life
Hanna Hammarström's full name was Johanna Hammarström. Her father, Per Hammarström, was a merchant who sold cotton and silk. Her mother was Christina Holmberg. Hanna's father wanted all his children to learn a skill or profession. So, Hanna learned how to make different kinds of decorations and ornaments. This skill involved working with metal strings.
Building a Career in Wires
Inventing Telephone Wires
Even though telephone wires existed, no one in Sweden knew how to make them. This meant that Sweden's first telephone network had to buy wires from other countries. Hanna Hammarström used her knowledge of making ornaments from metal strings. She figured out how to make telephone wires all by herself!
Starting Her Own Factory
Hanna started her own factory in Stockholm. In 1883, her factory began supplying telephone wires to the Swedish telephone company. For many years, through the 1880s and 1890s, she was the only one making these wires in Sweden. This is called having a monopoly. She was also friends with Lars Magnus Ericsson and Hilda Ericsson, who started the famous Ericsson phone company.
Training Women Workers
In her factory, Hanna Hammarström only hired women. She personally trained and taught them how to make the wires. Her factory made wires for several different telephone companies. In 1886, Hanna won a special first prize for her invention at a machinery exhibition in Stockholm. She continued to work at her factory until it closed in 1909. Hanna Hammarström passed away on November 27, 1914, when she was 85 years old.
