The Nokia History

Nokia's history starts in 1865, when engineer Fredrik Idestam established a wood-pulp mill in southern Finland and started manufacturing paper. Due to the European industrialization and the growing consumption of paper and cardboard Nokia soon became successful. In 1895 Fredrik Idestam handed over the reins of the company to his son-in-law Gustaf Fogelholm.
