Galileo Galilei was born in 1564. He grew up in a hard household. His parents argued often, but He and his father were very close. His father wanted him to have a good life, so he sent Galileo to a Missionary to study.
Galileo had a hunger for knowledge. He became an inventor and a physiologist. Galileo was very smart and was wanted by a school in Padua, Pisa. He became a teacher and taught his students all of his interesting new theories and inventions.
One of Galileo's most famous invention was the telescope. The telescope helped you see very far away things up close. Galileo used this to look at the stars, planets, and moon. This led him to the discovery that Aristotle's theory about the moon being smooth and flat was wrong.
One of Galileo's theories (Also backed up by his telescope) is that the planets DO NOT revolve around Earth. He believed that they revolved around the sun. Which we now know, in modern times, that he was correct.
Galileo was not favored by the Pope/Church officials for his theories. They would say that going against Aristotle's teachings were going against the Church and that he was a heretic. Galileo kept doing what he was doing until he was caught by Pope Urban and sentenced to a life of house arrest.
Galileo had three children but his favorite was his daughter Victoria. Victoria was a Nun and had died before Galileo died. He missed her greatly, but when he died, it was thought that Galileo heard the voice of his late father and daughter.
