Technology and Inventions of this century
The vacuum was invented in 1901 by Hubert Cecil Booth, who was a British Engineer. Booth first demonstrated his vacuum in a restaurant, and it was successful. Before people had vacuums, they hung their rugs outside on a wall or a line, and hit them repeatedly with a carpet beater, to get rid of as much dirt as possible.
The Portable Defibrillator
Invented in 1965, by Professor Frank Pantridge, the Portable Defibrillator saved many lives. This machine was used to check the heart's rhythm and send an electric shock to the heart to try to restore the heart back to it's normal rhythm. They are used to treat sudden cardiac arrests. This machine started at a weight of about 150 pounds, but by 1968, it weighed only six. They are now being used many times daily, across the world.
Insulin was discovered in 1921, by Frederick Banting, John Macleod, Charles Best, and James Collip. It had become a lifesaver, when treating diabetes. Insulin was discovered by injecting the hormone into a diabetic dog, and they found it lowered the dog's blood glucose levels to normal. Before insulin was discovered, people with diabetes didn't live very long, because there wasn't a lot that doctors could do for them.
The 1944 Education Act
The 1944 Education Act established the principle of free education. This was the most important piece of legislation of the 20th century, in the history of English education. Before this act, the 1930's were a decade of frustration for education reformers. Many didn't complete school before this act. This act was an attempt at structure for schools and education.
