Since 1889

The Mersen Group

Mersen’s roots lay in a technology that was about to play a decisive role in the coming electrical revolution : carbon arc rods. These would illuminate public spaces and large department stores from the 1870s.

As the electrical industry evolved, Mersen adapted, becoming a key supplier of carbon brushes for electric motors, essential for power transmission in countless applications. The merger of Maurice Lacombe's and Fabius Henrion's companies in the early 20th century marked a significant milestone, creating a robust entity that would grow into the Mersen Group known today. This union not only expanded the company's capabilities but also solidified its position as a leader in electrical components and advanced materials, setting the stage for over a century of innovation and growth.
