Marie Eugène François Thomas Dubois (28 January 1858 – 16 December 1940, pronunciation: French pronunciation: [øʒɛːn dybwɑ], roughly /ʌˈʒɛndjuːˈbwɑː/) was a Dutch paleoanthropologist and geologist. He earned worldwide fame for his discovery of Pithecanthropus erectus (later redesignated Homo erectus), or "Java Man". Although hominid fossils had been found and studied before, Dubois was the first anthropologist to embark upon a purposeful search for them.
Dubois was born and raised in the village of Eijsden, Limburg, where his father, Jean Dubois, was an apothecary, later the mayor. Interested in all phenomena of the world of nature, Eugène explored the "caves" ("grotten", actually underground limestone mines) of Mount Saint Peter and amassed collections of plant parts, stones, insects, shells, and animal skulls. From age 12-13 on, he attended school in the Limburg city of Roermond, boarding with a family there and then he dropped out. In Roermond he attended lectures on Charles Darwin's new theory of evolution given by the German biologist, Karl Vogt.
Resisting his father's plan for him to train to follow in his footsteps, Dubois, encouraged by his teachers, decided in 1877 to study medicine at the University of Amsterdam. While a student, he taught anatomy at both of the brand new (founded 1880) art schools housed at the Rijksmuseum Amsterdam (Amsterdam State Museum) the Rijksschool voor Kunstnijverheid (State School for Applied Arts) and the Rijksnormaalschool voor Teekenonderwijzers (State Normal School for Drawing Instructors). In 1884 he completed his medical degree. He declined an offer from the University of Utrecht of a position as a docent. Instead, at the invitation of his anatomy instructor, Max Fürbringer, he decided to train as an academic. From 1881 to 1887 he studied comparative anatomy and became Fürbringer's assistant. In 1885 he investigated the larynx of vertebrates, which led him to develop a hypothesis of the evolution of this organ. Nevertheless, his chief interest was in human evolution, influenced by Ernst Haeckel, who reasoned that there must be intermediate species between ape and human.
