He attended the primary and secondary school as a boarder at the municipal College of Chimay (Belgium), and was a student from 1879 to 1883 at the École Polytechnique, which was part of Brussels University.

He developed an electric lighting system in his father's residence, the Irminenhof in Rosport, even before he had completed his engineering studies.

During his vacations, he connected a Gramme type generator to the water-wheel of the Bannmillen, a mill located on the lower part of the property.

Henri Tudor had the idea of using lead acid accumulators as a buffer – to equalise the voltage and to store the unused energy.

The chemical reactions occurring in a lead-acid battery or accumulator were first observed by Wilhelm Josef Sinsteden [de] in 1854.

[4]" Henri Tudor sought a permanent solution to these problems and manufactured himself a mould for casting large surface plates with which he built a lead-acid accumulator of his own design.

With the combined equipment – generator and buffer battery – he was able to run continuously and constantly the power supply of the Irminenhof, which thus became the first private home in Luxembourg to have electric lighting.

They had three children and the young family moved in September 1892 into their newly built monumental Manor House in Rosport.

The Planté layer is strengthened during the charging and discharging cycles: the final formation of the Tudor plate happens during the actual use of the accumulator.

In order to avoid the smearing operation, which was laborious and hazardous, Henri Tudor was looking for ways to create a Planté layer by means of an accelerated electrochemical process.

[6] 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.

In 1889, he founded the Société Anonyme Belge pour l'Éclairage public par l'Électricité in Brussels so as to provide a more solid basis for his business activities in Belgium.

As from January 1897, following the dissolution of the Société Anonyme Franco-Belge pour la fabrication de l’accumulateur Tudor, the Rosport factory manufactured and marketed accumulators not only for Luxembourg but also for Belgium.

After spending a few hours with Henri Tudor, Müller was convinced that he had seen with his own eyes an innovation which could be developed on a large scale.

Henri Tudor took measures to make sure that his accumulator was manufactured and marketed in geographical areas where Adolph Müller had not been assigned any rights.

On 10 April 1889, he assigned the same rights to the Société Anonyme Belge pour l’Eclairage Public par l’Electricité, which developed a manufacturing site in Faches-Thumesnil, on the outskirts of Lille.

Just when the Tudor accumulator was about to embark on a spectacular upward trend on European markets, the Rosport factory, where it had all begun, was facing problems.

He also contributed to the prestige of the Tudor trademark in far-distant lands, thanks to the excellent performance of his company from every point of view.

[13] The Tudor brothers from Rosport lived in a rural environment which they wanted to open up to scientific and technological progress.

The new museum was to concentrate on the inventions of Henri Owen Tudor and their impact on industry, as well as on the man himself, his life, his family and his links with Rosport.

The bid from Wieland Schmid from the Mannheim Design Studio caught the eye of the Museum Working Group because of its original approach and educational value.

Professor Wolfgang Schmid, from the University of Trier, and the engineers Ernest Reiter and Henri Werner were appointed as advisers.

The architect Marcel Niederweis converted the north wing of the Tudor manor house from a number of small rooms walled off from each other into an attractive area flooded with light.
