Cosimo de Giovanni was born in 1389. He passed away in 1464. 
The first of the Medici political dynasty, de facto rulers of Florence during much of the Italian Renaissance; also known as "Cosimo 'the Elder'" ("il Vecchio") and "Cosimo Pater Patriae" (Latin: 'father of the nation'). His power derived from his great wealth as a banker, and he was a great patron of learning, the arts, and architecture.
Born in Florence, Cosimo inherited both his wealth and his expertise in banking from his father, Giovanni di Bicci de' Medici. His mother was Piccarda Bueri. Cosimo married Contessina de' Bardi (the daughter of Giovanni, count of Vernio, and Emilia Pannocchieschi). They had two sons: Piero the Gouty and Giovanni de Medici. Cosimo also had an illegitimate son, Carlo de Medici (1430-1492) by a Circassian slave, who became a prelate. On his death in 1464 at Careggi, Cosimo was succeeded by his son Piero "the Gouty", father of Lorenzo the Magnificent or Il Magnifico.
