20's inventions

     We are still benefitting from many of the inventions of the twenties. The refrigerator was brought out of the dust. It changed the convenience of the world today. Can you imagine life without a refrigerator? Always having to run to a cellar, salt your food, and yet go to the cellar to get the food. This could be a pain, especially in the middle of the winter. The refrigerator has replaced all of this. It was invented by Balzer Von Platen and Carl Munters in 1922 in Sweden. They named it the "D" fridge.
    Another invention for convenience was the method of freezing precooked foods. In 1925, Clarence Birdseye created this method, which took the food industry to a whole new level!
     Penicillin was discovered by accident in 1928 by Alexander Fleming. Doctors used the first samples of this antibiotic for World War II soldiers. Penicillin is still used frequently to cure illness.
