Eugène Dubois

Died 16 Dec 1940 at age 82 (born 28 Jan 1858). Dutch anatomist and geologist who discovered the remains of Java man, the first known fossil of Homo erectus. Dubois was the first person to ever deliberately search for fossils of human ancestors. Only a handful of fossil humans had already been discovered, and those were by chance. Dubois joined the Dutch Army as a medical officer, and used spare time from his medical duties to search for fossils, first in Sumatra and then in Java. He searched on the banks of the Solo River, with two assigned engineers and a crew of convict labourers to help him. After lesser finds, in Oct 1891 he found an intact skullcap, the fossil which would be known as Java Man, and in Aug 1892, an almost complete left thigh bone, was found about 10m away.
