An American inventor, scientist and businessman Thomas Edison developed many gadgets that have greatly changed life around the world including the phonograph, the motion picture camera and the electric light bulb. He was one of the first inventors to apply the principles of mass production and large teamwork to the process of invention. Edison was born in Milan, Ohio, in 1847.

He attended school for only three months as his mind often wandered and he was a poor student. His mother pulled him out of school and educated him at home instead. When he was 9, she gave him an elementary science book on how to do chemistry experiments at home. He was hooked: he did every experiment in the book. At the age of 10, he built his first science laboratory in the basement of his house. When he was 12 years old he started to have hearing problems but actually Edison liked being deaf. He said it helped him concentrate better on his experiments. He made his first important invention, a telegraphic repeating machine, in 1869, while working as a telegraph operator. This machine could record and reproduce sound and later became known as the gramophone or record player. Unfortunately, his voice-recorder was found to be impractical and it was a long time before it could be used commercially. After that, Edison decided that he would only invent something if there was a market for it.

The adding machine was invented in 1642 by a nineteen—year—old French boy Blaise Pascal. He was helping his father who had to do lots of calculations of taxes owed and paid. The boy’s invention was a wooden box with a set of dials on it. Turning the dials made it possible to do simple addition and subtraction quickly. In the following ten years Pascal produced about 50 machines called Pascaline but he didn’t sell many because of their cost and complexity. The fact that Pascaline could only add and substract, and the latter with difficulty, was a barrier to further sales and production stopped. However, this invention started the development of mechanical calculators which led three Centuries later to the invention of the first microprocessor. Throughout his life, Blaise’s health was extremely poor, but he was blessed with a brilliant mind. Initially, his father feared that learning mathematics might overstrain him, but it only made him more interested. Blaise Pascal, a philosopher, mathematician, and physicist, is considered one of the great minds in Western intellectual history.

Anton van Leeuwenhoek, born in Delft, The Netherlands, in 1632, is best known for his work on the improvement of the microscope. Double-lens microscopes had been built forty years before Leeuwenhoek was born. However, those early microscopes could magnify only twenty to thirty times. It was Leeuwenhoek who, in 1648, first produced microscopes capable of seeing cells — at the age of 16. He was not a scientist and he didn‘t have university education but his personal qualities, such as patience, curiosity, acute eyesight and observational skills led him to become one of the most important figures in the history of biology.

Leeuwenhoek made over 500 “microscopes". Compared to modern microscopes, this is an extremely simple device, using only one lens, placed in a tiny hole in the brass plate that makes up the body of the instrument. The specimen was mounted on the sharp point that sticks up in front of the lens, and its position and focus could be adjusted by turning the two screws. The instrument had to be held up close to the eye, requiring good lighting and great patience to use. At first Leeuwenhoek didn't communicate with other scientists because they were more highly educated than him, but in the end he began writing reports to the Royal Society in London describing his observations. He became famous for his reports and was elected to the Royal Academy.
