George Stephenson was born in 1781 in a poor family. He had to start work when he was only eight. When George was fourteen, he became his father’s helper. He spent a lot of time learning about engines. On holidays, he often took engines into pieces and studied each piece carefully. Soon he became a very good worker though he could not read or write.
He began to learn the English letters when he was seventeen years old. Every day after he did twelve hours of hard work, he walked a long way to have lessons from a young teacher.
On his eighteenth birthday, he wrote his own name for the first time in his life. George invented many things in his life. The train was the greatest one among them. Today when we watch or take trains from one place to another, we will think of this great man—George Stephenson.
