This would be at the origin of his most important contribution to the deployment of long-distance telephony by developing an anti-inductor system which made it possible to dispense with having to pull new telephone cables between two geographically distant points since the signal borrowed the existing telegraph cabling. In France, a first link was established on the basis of this process between

The city of Antwerp gave him carte blanche to deploy his invention to power the city's public lighting and it is when he was busy with this task that he died on 3 February 1893, at the age of 46, carried away in two days by a devastating disease.

Although his basic education was literary, he was interested in science and particularly in mathematics and physics and took courses at the industrial school. In 1865 he successfully passed an examination for the post of second professor of mathematics at the

A great limitation of the weather models he could build was related to the fact that at that time, meteorologists could only count on a single 40-point reading in Europe and transmitted at eight in the morning local time.

Observatory of Belgium to turn resolutely towards telecommunications. In 1883, he designed a multiplex phonic telegraph that could simultaneously transmit up to 24 messages. The device received the full attention of the

In 1884, having donated his Van
