In 1796, Candolle moved to Paris after receiving an invitation from French geologist Déodat Gratet de Dolomieu.
His ship, caught in a storm, sought refuge at the port of Taranto, Italy where De Dolomieu was made a prisoner of war.

In 1795, having lost his fortune in the revolution, De Dolomieu accepted the position of Professor of Natural Sciences at the École Centrale Paris and started to write the mineralogical section of the Encyclopédie Méthodique.
•
For this infraction he was sentenced to life in prison but due to the intercession of Pope Clement XIII he was released after only 1 year.
•
Through his friend and mentor, the Duke de La Rochefoucauld, De Dolomieu was made a corresponding member of the Royal Academy of Sciences.
