Towering Scientists: The invention that saved thousands of ships and lives • RFI English

The Fresnel lens is named after its inventor, the French engineer and physicist Augustin Fresnel, whose name is engraved on the École Militaire side of the Eiffel Tower. It quickly became essential to lighthouses, greatly extending the range of their beams and transforming maritime signalling, saving countless ships and lives.
