He made wires, columns of air, and solids vibrate. He wrote in his native German language, but his French scientist friends wanted to read it in French. In February 1809, Chladni’s friends took him to meet French Emperor Napoleon Bonaparte. Would the Emperor give Chladni enough money to write the French book?
