Task 10. Edison’s First Invention
- When Edison was a boy of fifteen, he worked as a telegraph manager.
- But at night there was much work and the telegraph operators usually worked hard.
- The boss ordered each operator to give a signal every ten minutes to show that he was awake.
- Edison’s signals always came at the same time, at the beginning of each new hour.
- One night the boss sent his mother to see how well the boy was working.
- So one day the boss sent an inspector to see how well the boy was working.
- When the inspector opened the door, he saw Edison sleeping in his chair.
- The inspector saw a block with a mechanism on the table.
- The inspector wanted the boy to show how the mechanism could work.
- Edison awoke and was told that he had lost his job.
- This story explains why the first of Edison’s many inventions was patented.
