Johannes Kepler was a German astronomer, inventor and mathematician from the 17th century. He is best known for creating the laws of planetary motion. He was one of the most influential figures in the scientific revolution. If you are studying astronomy, and planets you will enjoy learning about Johannes Kepler.

He is most known for the discovery of the three laws of planetary motion. This made him the chief founder of modern astronomy. These laws were actually the foundation for Newton’s theories about gravity. Do your children ever look up at the night sky and wonder how every thing moves and works? Kepler was the one who figured that out!
In order for him to understand planetary motion he had to invent quite a few things to help him discover that first. Many people don’t realize that not only was he a famous astronomer, he was also a great inventor. He laid the ground work for some pretty great inventions.
Johannes Kepler Inventions:
- Eyeglasses – if you wear glasses to correct your vision, you can can thank Johannes Kepler for that. He worked with the lenses in the eyeglasses so that people who were both near and far-sighted would be able to have their vision corrected.
- Log Books – He actually created a scientific log book. There were no log books, or spreadsheets or ways to keep track of data in the 17th century. He recorded all of his observations and left room for others to be able to do the same and continue his studies.
- Kepler Telescope – The telescope gave a wider view of the sky than other telescopes of that time period. The images from the telescope could be projected to a white screen to be tracked for research.
- Rudolphine Tables – this was a catalog of stars, and planetary tables along with a printable map of the world at that time. Named after a famous Holy Roman Emperor.
- Astronomia Nova – This is his most famous published work. It was a ten-year-long investigation of the motion of Mars. This is considered one of the most important books in astronomy. All the famous scientists read and devoured his work.
Johannes Kepler Biography:
Johannes Kepler was born on December 27, 1571, in Weil, Germany. He contracted small pox when he was only 3 years old, and was a very sickly child. This led to vision issues later in his life. His parents took him to see his first eclipse when he was only 5. They took him to see stars and comets too.
He became fascinated with planets and the night sky as he was growing up. In 1580 he witnessed his first eclipse of the moon. He went on to study math and astronomy and studied under Nicolaus Copernicus.
