Stanislas-Charles Dupuy de Lôme started his career at the port of Toulon once having graduated from Ecole Polytechnique and then from Ecole Navale in Lorient. There he investigated ship resistance based on the work of his former teacher Ferdinand Reech (1805-1880) and made a report on the pros and cons of iron boats which have been shortly earlier designed by the English. He was responsible for the two ships Caton and Ariel and provided propeller propulsion as early as in the 1840s. Both ships made memorable speed records. After this success, Dupuy tried to integrate steam machinery into war ships. The boat Napoléon was designed in 1848 and put to water in 1851; its maximum speed was 13 knots and its advantages were tested in the Crimea War in 1853. In 1857, Dupuy was appointed director of naval constructions and was in charge to continue with the supremacy in the French fleet over Britain. In 1860 three novel armored frigates were launched of which others were successfully employed later in the American Civilian War.

In 1870, during the French-Prussian War, Dupuy proposed to the surrounded capital controllable balloons for communication with the suburbs. A so-called aerostat was launched in 1872: The balloon moved with a propeller fixed at its rear using human force, and transported mail from the capital to Vincennes. Others would develop this basic flying machine within the following decades, thereby accounting for Dupuy's early invention. He was awarded Member of Académie des Sciences in 1866 and was a senate member from 1869.
