The first bimagic square of the world

The Frenchman Georges Pfeffermann discovered the first bimagic square in 1890 and published it on January 15, 1891 in the magazine Les Tablettes du Chercheur in the form of a puzzle. Only some numbers were entered, and other fields remained empty. 14 days later the solution was presented.
