Dupleix was born in Landrecies, France. His father, Francois Dupleix, a wealthy fermier general, wished to bring him up as a merchant, and, in order to distract him from his taste for science, sent him on a voyage to India in 1715 on one of the French East India Company’s vessels. He made several voyages to the Americas and India, and in 1720 was named a member of the superior council at Pondicherry. He displayed great business aptitude and in addition to his official duties, made large ventures on his own account, and acquired a fortune. In 1730 he was made superintendent of French affairs in Chandernagore. The town prospered under his administration and grew into great importance. In 1741, he married Jeanne Albert, widow of one of the councillors of the company; Albert was known to theHindus as Joanna Begum and proved of great help to her husband in his negotiations with the native princes.
