The Mazzei family's winemaking influence has extended far beyond the realm of Tuscany. In 1774, Filippo Mazzei (1730-1816) was asked by his friend Thomas Jefferson to plant a vineyard at the Jefferson estate in Monticello, Virginia. Jefferson was inspired not only by Filippo's (Philip's) viticultural knowledge but also by his ideas regarding equality. The great doctrine "All men are created equal" which was incorporated into the Declaration of Independence by Jefferson, was paraphrased from the writing of Philip Mazzei. Philip's highly significant contributions to Italian American culture and philosophy were commemorated on a U.S. postage stamp entitled "Patriot Remembered".
