Bartolomeo Cristofori di Francesco was born on May 4, 1655 in Padua, Italy. He served as a master of preparation and tuning of keyboard musical
instruments in the court of Prince Ferdinand de' Medici.                                                                                                                                                This is how the musical instrument – piano appeared. Bartolomeo Cristofori is considered as the inventor of the piano musical instrument. In 1698, he named his new type of instrument "gravicembalo col piano e forte", which means "low and high sounding harpsichord". Around 1709, an Italian piano manufacturer placed hammers under the strings.
In France in 1716, a similar innovation was developed by Jean Marius and in 1717 by the German music theorist, composer and organist Christopher Gottlieb Schroeter.
