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.
