Join Patrick Llewellyn as he discusses the unpublished Fleurieu chart and why dozens of French names dot Australia's coastline at the National Library of Australia. This special event will feature this important map, together with two marine chronometers used to draw it: a Berthoud from the Baudin expedition and an Earnshaw from the Flinders expedition. Never before have chronometers from both expeditions been displayed together anywhere in the world. Patrick Llewellyn is President, Institut de recherche Nicolas Baudin. He is French and has a degree in humanities. For almost 12 years, he has specialised in the history of the great scientific maritime expeditions of the 18th century, in particular that of Nicolas Baudin, the battle of the longitudes and marine chronometers. He was involved in organising the Art of Science exhibition in Australia in 2016, dedicated to Captain Baudin's expedition, and facilitated the loan to Australia from the Musée National de la Marine in Paris of one of only two surviving marine chronometers from the Baudin expedition, and the large copper plate used to engrave the first complete map of the Australian coastline in Paris in 1811. Patrick gave numerous lectures in Australia in 2015 and 2016.
