Dishwasher was invented by Jozefien Kokrein. The idea came to her when somebody in the kitchen broke her favorite porcelain set while cleaning it. She wanted to have a machine which will clean the dishes and not break. But the way of achieving her idea was quite long. When her husband died, he left her a lot of debts. As soon as women didn’t want to sell her property, so she focused on her machine. She got a patent, she constructed the machine but the problem was that nobody wanted to buy it. People believed it is useless to pay for something that woman can do for free. But she never gave up and step by step gained people’s trust. Nowadays most of us find this device very helpful.
