On 30 April 1886, Henri Tudor signed a convention with the Town Council of Echternach concerning the replacement of the existing petroleum street by electric lighting. It was understood that the electric power plant would include a steam boiler, two dynamos and Tudor lead-acid accumulators. For the execution of this project, he founded with his brother Hubert and his cousin Nikolaus Schalkenbach, the firm "Tudor Frères & Schalkenbach" and established workshops in Rosport. The electric lighting system went on stream on 24 October 1886. Echternach was proud to be the first town in the country to benefit from electric lighting.
