7Stapler (unknown)
Staples have been used since 1200 C.E. Academics would use ribbon or wax in the upper-left corner to keep pages together. But the more modern staple we know was invented by an inventor in France for the King Louis the XV during the 18th century. It was invented because paper was being used more and more so people needed a way to keep their papers neat.
8Mayonnaise (unknown chef)
Can we say that many food classics were invented by French people? It is said that mayonnaise was invented by the Duke of Richelieu’s chef when they conquered the Port of Mahon located on the Spanish island of Minorca. To celebrate the defeat of the Spanish, the Duke ordered his chef to make a huge banquet but the chef could not find enough cream to make his sauce so he used eggs and oil instead to create mayonnaise.
9Aspirin (Charles Frederic Gerhardt)
Before aspirin, people used willow tree leaves to relieve pain but in 1853, the French chemist Charles Frederic Gerhardt mixed sodium salicylate with acetyl chloride and created acetylsalicylic acid (aspirin). Once the mixture was shared, other chemists found a more efficient way to create it. It soon became world-wide when Bayer (a German pharmaceutical company) named it aspirin in 1899.
