Galileo Galilei

Portrait of Galileo Galilei by Italian Baroque era printmaker and painter Ottavio Leoni (1578-1630), 1624, active mainly in Rome where he first trained with his father, Lodovico Leoni. Galileo Galilei (15 February 1564 – 8 January 1642) was an Italian physicist, mathematician, astronomer, and philosopher who played a major role in the Scientific Revolution.

Galileo has been called the "father of modern observational astronomy", the "father of modern physics", the "father of science", and "the Father of Modern Science." Stephen Hawking says, "Galileo, perhaps more than any other single person, was responsible for the birth of modern science."
