Gérard Sébastien Bernizet (March 2, 1760 – May, 1788) was a French cartographer and geographical engineer. His best known for his work as chief cartographer on the La Perouse Expedition (1785 – 1789). Bernizet can be credited with many of the cartographic advances (and errors) associated with the expedition. The La Perouse expedition shipwrecked on the island of Vanikoro, part of the Santa Cruz group in the Solomon Islands. Although some of the sailors may have survived the initial shipwreck, none ever returned to Europe. The records of the La Perouse expedition survive because La Perouse prudently sent copies of his journals back to Europe onboard ad British Nave ship from the First Fleet (The Alexander) which he encountered en route.
