Mapmaker: Jean-Baptiste Chappe d'Auteroche (March 23, 1722 – August 1, 1769) was a French astronomer and explorer. He was born to a noble family of Auvergne, France. He entered the priesthood where is was able to dedicated himself to the study of Astronomy. he was appointed assistant Astronomer at the Royal Observatory and, on January 14, 1758, was admitted to the Paris Acadйmie des Sciences. Auteroche is best known for his observation of the Transit of Venus in 1761 and in 1769. The scientific world at the time recognized an unprecedented opportunity to determine the size of the Solar System using exact observations of the Transits of Venus in 1761 and again in 1769. By applying the calculations associated with these transits in the light of Kepler's Laws of Planetary Motion, it was possible to determine for the first time the distance between planets. Auteroche's first expedition led him to Siberia, where is observed the 1761 transit from Tobolsk. He observed the second transit, in 1769, from Baja California in Mexico. On the return voyage the crew of Auteroche's ship were struck by Yellow Fever. With the exceptional of a single passenger, everyone on board, including Auteroche, died. That survivor managed to salvage Auteroche's notes and return them to the Acadйmie des Sciences in Paris. Auteroche's notes and journals were published posthumously by Cesar Cassini de Thury.
