Life and career

Born in Leuven on July 11, 1814, Melsens was first home-schooled by his mother. He then went on to high school in Leuven. He studied ancient languages, as well as English, German and Italian, and began his career in the offices of a commercial firm in Antwerp, with the Josson brothers. DE HEEN, Pierre
"Notice sur Louis-Henri-Frédéric Melsens"
in ''Annuaire de l'Académie royale des Sciences, des Lettres et des Beaux-Arts de Belgique'' , 1893, p. 484-493.
Not really having a commercial streak, he decided to devote the rest his life to the study of science. On the advice of his mother and his fellow student Jean Servais Stas, he went to Paris to study chemistry and physics in

Streets and scientific award named in his honor

The ''Louis Melsens Prize'' is awarded to a Belgian or naturalised Belgian author of the most remarkable work on applied chemistry or physics.Louis Melsens Prize
(created in 1900)
The Melsensstraat or Rue Melsens in Brussels and the Louis Melsensstraat in Leuven are streets named after him.
