Do you know Laszlo Biro? Maybe you do not, but you probably use his invention every day, and you may even have it in your hand right now!
Biro(1899-1985) was the inventor of the ballpoint pen. He was born in Budapest, Hungary. In the 1930s, when he worked as a newspaper editor, he used a fountain pen almost every day. However, he had to refill it all the time. The ink also did not dry easily, and it sometimes made a mess on the paper. Biro wanted a better pen. His brother, George, helped him develop a special ink. The ink dried easily. Then they developed a new type of pen. There was a tiny ball at the tip of the pen. The ball rolled ink onto paper as it move. They called it the “ballpoint” pen.
The Earl of Sandwich was an Englishman. He lived in the 18th century. The Earl of Sandwich was rich, but he liked to play cards for money. He often played for 24 hours, and didn’t even stop to have his meals. He ordered his servants to bring him some meat and bread. He put the meat between the two pieces of bread and held the food in his left hand and played cards with his right hand.

The wheel The wheel is perhaps the greatest invention in history. After its invention, travelling became faster and more comfortable. A few thousand years ago, people started to use wheels on carriages. In the early 19th century, the first trains began to carry passengers. At the start of the 20th century, cars became popular. Without the wheel, we would not have these inventions.
