The bicentenary of Georg Hartung, a German pioneer geologist, explorer, and illustrator. History of Geo-and Space Sciences, 12(2), 217-223.http://hdl.handle.net/10400.13/5324We present a tribute to Georg Friedrich Karl Hartung (1821–1891), a less-known, non-academic German geologist, on his 200th birthday anniversary. Influenced by eminent 19th century scientific personalities, such as Oswald Heer, Charles Lyell, and Alexander von Humboldt, he performed pioneer geological observations and sampling in the Azores, Madeira, and Canary Islands volcanic archipelagos. Later in his life, he travelled to the USA and explored the Scandinavian countries. His scientific endeavours were published in several books and papers, many of them co-authored by academic German geologists and palaeontologists. His works on Macaronesia are deemed as classics, and many have been enriched by his detailed geological illustrations.engGeorg HartungBiographyGeologistIllustrator.Faculdade de Ciências da Vidajournal article10.5194/hgss-12-217-2021
