Numerous fields of Life and Earth Sciences as well as Human Sciences are indebted to Alcide d’Orbigny for his huge and innovating work. From his long journey in South America, he brought back a rich wealth of scientific collections and information related to Botany, Zoology, physical and human Geography, Geology, and Ethnography. Founder of Micropalaeontology, by his foraminiferal studies, and of Biostratigraphy, he is still present in Sciences today thanks to the numerous implications of his works in numerous domains of both academic research and economic sector.
