About the author
Born in Bar-le-Duc on July 22, 1862, Lucien Poincaré was a French physicist who also became an important figure in education and public life. He came from the notable Poincaré family: he was the brother of Raymond Poincaré, who later served as president of France, and a cousin of mathematician Henri Poincaré.
After an accomplished academic career, he rose through major roles in French education, serving as inspector general of physical science, then director of secondary education, director of higher education, and finally rector of the Académie de Paris. Alongside that administrative work, he wrote books such as La Physique moderne and L'Électricité, reflecting his interest in making scientific ideas understandable and useful.
He died in Paris on March 9, 1920. Remembered today as both a scientist and an educator, he stands out as a writer who helped connect modern physics with the broader world of schools and readers.
