Explanation:

The stethoscope, a doctor's indispensable - 1816

The first entry on our list of the greatest French inventions has saved innumerable lives. This lifesaver was the humble stethoscope that was devised by the French physician René Laennec in 1816. It would immediately become one of the most important non-invasive medical instruments in the doctors' kit.  It works by using a small disc-shaped resonator to amplify the internal sounds of the patient.

The Etch-a-Sketch is French! - 1955-56

A French electrical technician, inventor, toymaker, and kite designer, André Cassagnes, designed one of the most popular toys of all time in the later 1950s.

These toys are effectively plotters. Etch-a-sketches work by scraping off aluminum powder on the inside surface of the main glass screen.

The knobs are used to control internal styluses that scrap off the powder coating, leaving a visible dark line.
