Belgian physicist and inventor whose patent registered in 1882 is thought to be the original invention of the basis of the phonopore (condensor) method of telephone voice communications. The technique was developed and improved by Charles Langdon-Davies in 1890, particularly with the invention of a method to call between phones. Rysselberghe was a Professor of Physics at the Industrial School of the Ostend School of Navigation. He died in 1893.
