Charles C.-J. Le Roux (born 1724) was a French educator, inventor, and physicist. Le Roux began teaching around 1758 in Amiens, France, and relocated to Paris some ten years or so after that, working there as Maître de Pension at a boarding school. During this time, he also held public scientific experiments and became the main author of the Journal d’Éducation, the first periodical dedicated to the educational landscape in France. In this publication, he advocated for a different approach to teaching children: specifically one with less emphasis on learning Greek and Latin, and more consideration placed towards the character and quality of the instruction itself.
