Jean-Baptiste Charles Bouvet de Lozier
He was orphaned at the age of seven and after having been educated in Paris, he was sent to Saint Malo to study navigation. He became a lieutenant of the French East India Company in 1731. He succeeded in convincing his employer to provide him with two ships and send him on an exploration mission in the South Atlantic. With his ships Aigle and Marie he discovered on 1 January 1739 a tiny island which was named Bouvet Island after him; however, he mislabeled the coordinates for the island, causing it to be lost until it was rediscovered seven decades later in 1808. Shortly afterwards, he had to abandon the expedition because most of his crew had fallen ill; his ship then called at the Cape of Good Hope and returned to France.
