Florentin-Étienne Jaussen, SS.CC., (2 April 1815 – 9 September 1891) was the first bishop of Tahiti and the man who brought the rongorongo script of Easter Island to the world's attention.

In 1855, he purchased a large estate near the city to ensure economic independence for the missions and developed the cultivation of coconut, sugarcane, and vines, among other activities.

In 1868, in gratitude, Easter Islanders residing in Tahiti gave him a strange wooden tablet with curious inscriptions.

Jaussen managed to establish a chronology of the island's kings spanning a thousand years and proposed a translated repertoire of the most important ideograms.

Although his translations are now questioned, Jaussen succeeded in creating nine categories covering gods, humans, land, sea, animals, plants, objects, actions, and composite signs.
