László Biró was born in Budapest in 1899. After he left school, he studied medicine at university, but he didn’t finish his studies. He did a number of different jobs and then became a journalist in the 1930s.He noticed that newspaper ink dried very quickly on the paper, and put the ink into his fountain pen. However, it didn’t work because the ink was very thick. He and his brother Gyõrgy then invented a new type of pen with a small ball at the end. The new pen worked with the thick ink. It quickly became popular all over the world. In 1939, Biró moved to Paris and then to Argentina. Biró invented many other things but the most important was the ball-point pen, or “biro”. László Biró died in Buenos Aires in 1985.
