German prodigy Jean-Philippe Baratier squeezed a lifetime’s work into less than two decades. Born in 1721 to a Huguenot minister near Nuremberg, he was polyglot from birth — his father spoke to him only in Latin, his mother in French, and the servants in High Dutch. By age 5 he was reading the Old and New Testaments in Greek and translating them into Latin and Hebrew. He matriculated at Altorf at 10, and three years later he was introduced to the king of Prussia and received into the Royal Academy. His interests expanded into navigation, astronomy, and history, including the Thirty Years’ War, the succession of bishops of Rome, and an inquiry into Egyptian antiquities. When he died at age 19, he left behind 11 published works and 26 manuscripts.
