Transcript of The Enigma Machine

Brief History
The Enigma coding machine was invented by Arthur Scherbius. It had many improvements as years went by, and it was eventually used in WWII for Germany. The machines sent coded messages from operator to receiver. The German army was so confident in their machine and thought the Allies wouldn't be able to decode it. A German coder betrayed his country and gave vital information to the French, British, and Polish code breakers. The Enigma is historically significant because settings lists and instruction manuals eventually helped the Allies break the Enigma code and defeat Germany in war.
