Birthplace of Vincenzo Galilei at the junction of Via Mercanti & Borgo Stretto in Pisa, Italy
Vincenzo Galilei (3 April 1520, c. 1520, or late 1520s – buried 1 or 2 July 1591) was an Italian lutenist, composer, and music theorist, and the father of astronomer and physicist Galileo Galilei and the lute virtuoso and composer Michelagnolo Galilei. He was a seminal figure in the musical life of the late Renaissance and contributed significantly to the musical revolution which demarcates the beginning of the Baroque era.
In his study of pitch and string tension, Galilei produced perhaps the first non-linear mathematical description of a natural phenomenon known to history. It was an extension of a Pythagorean tradition but went beyond it. Many scholars credit him with directing the activity of his son away from pure, abstract mathematics and towards experimentation using mathematical quantitative description of the results, a direction of utmost importance for the history of physics and natural science.
