Lislet Geoffroy was born on 23 August 1755 in Saint-Pierre, Réunion and died on 8 February 1836 in Port-Louis (Mauritius).
[1] Lislet was the son of Jean-Baptiste Geoffroy, a white, French engineer working in Mauritius (then called Ile de France) and Niama, an enslaved Senegalese princess.
Lislet Geoffroy stated that his mother was named Niama and was the daughter of Toucu Niamba, King of Galam (in modern-day Senegal).
Outside of geography, he worked in geology, showing that the shoal, Isle Plate around Mauritius was formed by the debris of the crater of a volcano.
Avoiding the reign of terror, he was commissioned in 1794 to visit and chart the Seychelles, and his success there earned him the promotion to assistant-officer in the body of military engineers.
