Galileo, in full Galileo Galilei, (born February 15, 1564, Pisa [Italy]—died January 8, 1642, Arcetri, near Florence), Italian natural philosopher, astronomer, and mathematician who made fundamental contributions to the sciences of motion, astronomy, and strength of materials and to the development of the scientific method. Galileo Galilei was born in Pisa in the Duchy of Florence, Italy, on February 15, 1564. Galileo was the first of six children born to Vincenzo Galilei, a. Galileo Galilei, born on 15th of February 1564, in the Florentine City of Pisa. He was the eldest of seven children of musical theorist Vincenzio and Giulia Ammannati.

Galileo Galilei (1564-1642) – Italian astronomer, scientist and philosopher, who played a leading role in the Scientific Revolution. Galileo improved the telescope and made many significant discoveries in astronomy.
His findings encouraged him to speak out for the Copernican view that the earth revolved around the sun. Galileo Galilei was born in the Italian city of Pisa on February 15, 1564. He was the eldest son of Vincenzo Galilei and Giulia Ammannati. His father was a well-known composer, who played the lute, a stringed instrument. Galileo also became a skilled lute player.

In 1989, NASA and a team from Germany launched a spacecraft bearing Galileo’s name from the cargo bay of space shuttle Atlantis. Galileo studied speed and velocity, gravity and free fall, the principle of relativity, inertia, projectile motion and also worked in applied science and technology. In 1589, he was appointed to the chair of mathematics in Pisa. According to legend, Galileo began his study of the pendulum while watching a lamp swing back and forth in the cathedral of Pisa. The most important of Galileo’s inventions is the telescope. Along with Englishman Thomas Harriot and others, among the first to use a refracting telescope as an instrument to observe stars, planets or moons. On 7 January, Galileo observed with his telescope what he described at the time as "three fixed stars, totally invisible by their smallness", all close to Jupiter, and lying on a straight line through it. He published his initial telescopic astronomical observations in March in a brief treatise entitled Sidereus Nuncius (Starry Messenger).
The name "telescope" was coined for Galileo's instrument by a Greek mathematician, Giovanni Demisiani, at a banquet held by Prince Federico Cesi to make Galileo a member of his Accademia dei Lincei.
