Dupré's family originated initially from France, but settled long time ago in Tuscany (Italy). Giovanni Dupré was born in Siena in 1817, and died in Florence in 1882. His father was already a carver (in wood).http://www.britannica.com/biography/Giovanni-Dupre

Numerous sculptures done by Dupre can be seen in Tuscany, like the Savonarola bust, which is visible in his cell at the monastery of San Marco in Florence. And a museum existed previously, managed by a relative of Dupre (Amalia), located in Fiesole, a wonderful hill near Florence. Unfortunately that museum is now closed.
Dupre wrote his memoirs (Pensieri sull'arte e ricordi autobiografici) in 1879, and it was later translated into English by F. Peruzzi (Edinburgh, 1886).
