The Pisani family is a Venetian patrician family, originating from Pisa, which played an important role in the historic, political and economic events of the Venetian Republic during the period between the 12th and the beginning of the 18th century.
The principal male line of the family, namely the Pisanis of Santo Stefano, died out at the end of the 19th century. However, at the very beginning of the 20th century, the remaining Pisani children moved to America, where their greatgrandchildren now live.
