The American politician Thomas Jefferson (1743-1826) was born in Shadwell in the US state of Virginia as the son of a tobacco planter. As one of the champions of a free America, he formulated the first draft of the US Declaration of Independence. In the period 1785 to 1789 he was US envoy in Paris and and in 1787 and 1788 visited many wine-growing regions in France and Italy to study viticulture. He kept detailed descriptions of the Bordeaux wines and rated the best estates; including Château Carbonnieux (Graves) and Château-Grillet (Rhône). His rankings were used in the Bordeaux classification decision in 1855. He sent 30 bottles of Château d'Yquem, which he visited in 1787, to his friend and first US president George Washington (1732-1799).
