Lippmann is a painter in Florida, USA. As a little-known painter, his life is too poor to buy even better painting tools.
One day, Lipman was drawing a sketch. His only pencil was cut short, but he had no money to buy a new pen, so he had to draw with the tip of a pencil. Drawing and painting, he found that somewhere in the painting needed to be revised, so he put down his pen and began to look for his only eraser in the messy studio.
After searching for a long time, he finally found the little eraser, which was not much bigger than the soybean. But when he cleaned up the place that needed to be modified, he found that the small pencil head disappeared inexplicably, and Lippmann had to look for the pencil again. As a result, I found this, lost that and looked everywhere, which delayed a lot of time.
At this time, the painter finally got angry. He vowed to find these two hateful things and tie them together so that no one can escape. So, after he found the pencil and eraser, he found a silk thread and tied the little eraser to the top of the pencil. This pencil seems a little longer, which is more convenient to use and encourages painters.
But after a few useless strokes, the silk thread loosened and the rubber fell off. At this time, the painter's stubbornness came up. He didn't even paint. He worked hard for several days and tried many ways to repair the little eraser, but the eraser just didn't listen to his instructions and kept fighting him.
Lippmann kept trying and trying. Finally, he came up with a unique trick: cut a small piece of thin iron sheet from the can, connect the eraser and pencil together and wrap the middle. This time, he finally succeeded, and the rubber-tipped pencil we use today was born!
Lippmann came out of the studio with his masterpiece. What he took out was not a painting, but his invention. He applied for a patent for this invention, which was soon confirmed.
Soon, the famous RABAR pencil company bought the patent for a huge sum of 550 thousand dollars. Lippmann got out of trouble and became a celebrity, but it was not the painter but the inventor who was praised by later generations.
