Charles Hahn
Three generations of men named Charles Hahn were involved in the ebauche factory of Hahn Frères in Le Landeron.
Charles-Alfred Hahn
Charles-Alfred Hahn was born in the 1820s in La Chaux-de-Fonds. His father was apparently also Aimé-Auguste Hahn like his brother.
After his brother Aimé-Auguste Hahn's joint venture with David-Henri Tissot-Vougeux failed in 1844, the two brothers started their own company. Called Hahn Frères, it was officially established on December 31, 1844.
Charles-Alfred Hahn died in 1875 or 1876, leaving his share of the company to his son, also named Charles Hahn.
Charles Hahn
The second generation to operate the family firm was also named Charles Hahn. He formed a joint venture with his uncle Aimé-Auguste Hahn and La Chaux-de-Fonds watchmaker Charles-Frédéric Couleru in 1879 to operate the factory. This was dissolved and renamed Charles Hahn & Cie in 1889, with Aimé-Auguste no longer an owner.
Charles-Alfred Hahn
The third generation Charles Hahn joined the company's management in 1907.
On October 25, 1912, Charles-Alfred Hahn took over the firm completely.
