Jules Paul Benjamin Delessert directed the family bank in Paris for fifty-two years, spanning a career that bridged industrial innovation, parliamentary service, and large-scale natural history collecting. Born in 1773, he navigated the complex transition of post-revolutionary France by balancing his roles as a regent of the Banque de France with extensive philanthropic and scientific contributions.
Early Life and Education
Born in Lyon to Étienne Delessert, founder of the first French discount bank, Benjamin moved to Switzerland with his family before returning to France. In 1784, he traveled to the University of Edinburgh to study, where he encountered figures such as James Watt and Adam Smith. His education was interrupted by the French Revolution, leading him to return to Paris to serve in the National Guard and later as an artillery officer in Belgium and the Netherlands.
