Java Man
The fossilized skullcap was discovered in February 1936 by Andojo – sometimes referred to as Tjokrohandojo or Andoyo – an Indonesian who worked at excavating animal fossils in the Kendeng Hills ("Pegunungan Kendeng") in East Java on a team led by Ralph von Koenigswald. Andojo originally believed the skull belonged to an orangutan, but von Koenigswald immediately recognized it as human. He named it "Pithecanthropus modjokertensis" after the nearby town of Mojokerto, which was then spelled "Modjokerto". Eugène Dubois, who had discovered Java Man in the 1890s and named it "Pithecanthropus erectus", wrote to von Koenigswald arguing that if the Mojokerto fossil were indeed human, then it could not be a "Pithecanthropus" (lit., an "ape-man"). Von Koenigswald thus renamed his fossil "Homo modjokertensis". It was eventually classified as "Homo erectus" just like "Java Man" and the numerous early human fossils that von Koenigswald and others found in Sangiran. In Indonesia, the fossil is known as "Pithecanthropus modjokertensis".
