Today, we tell about the discoveries of ten important scientists of the past 1,000 years.

The earliest of these important scientists was Johannes Gutenberg. He lived in Germany from about 1395 until about 1468. Johannes Gutenberg invented the type mould and the first successful system of movable type used in Europe. This made printing books faster and easier. Johannes and others used his invention to produce books in the City of Mainz during the 1400s. The system he invented remained unchanged for 350 years.

Nicolaus Copernicus was another important scientist. He is considered the founder of the modern science of astronomy, the study of the planets and stars in the universe. Nicoluas Copernicus was born in Poland in 1473. At that time, most scientists accepted the idea that the earth was at the center of the universe and did not move.
