Passage

The ball-point pen was invented by a Hungarian called Lasso Biro. He was a man of many talents. He was a journalist, painter, sculptor, and hypnotist. As an editor, it was his job to select, correct, and sometimes compose articles. This meant considerable paperwork for which he used a fountain pen. Sometimes it scratched the paper. Sometimes it overflowed leaving blobs of ink on the writing. He had to change the paper and rewrite it again. All these interruptions irritated Biro. He always dreamed of a pen without these flaws. He worked on it and ultimately succeeded in designing a pen that answered his expectations. Technically it was a super discovery but its production was expensive. For some time it remained a funny item. It soon caught the attention of air force pilots who found it ideal for high altitudes since it did not depend on gravity and went on writing without having to be ink-filled now and then. Gradually the pen became so famous that in the first market sale organized in 1945 in New York, the entire stock of 10,000 pens was sold out on the same day. The people wanted to be the first owners of the miracle pen
