"Giovanni di Cosimo de' Medici (3 June 1421 – 23 September 1463) was an Italian banker and patron of arts.
Giovanni was the son of Cosimo de' Medici the Elder and Contessina de' Bardi, and brother to Piero the Gouty. Unlike the latter, Giovanni enjoyed good health and was seen by Cosimo as his probable successor. From 1438 he directed the branch of the family bank in Ferrara. He received also a humanistic education, showing a major interest in music.
In 1454 Giovanni was elected Prior of Florence and the following year he was a member of the delegation which received Pope Pius II in the city. The following year Cosimo made him general director of the Medici bank, but, unsatisfied because of Giovanni's distraction in arts and other activities, assigned to him Francesco Sassetti as tutor." - (en.wikipedia.org 25.05.2024)
