From Today in Science History:
Sir Edwin Ray Lankester (Born 15 May 1847; died 15 Aug 1929). British zoologist whose interests embraced comparative anatomy, protozoology, parasitology, embryology and anthropology. He was one of the first to describe protozoan parasites found in the blood of vertebrates. Lankestrella (a parasite related to the causative agent of malaria) carries his name. His work contributed to an understanding of the disease. Based on his investigation into the comparative anatomy of the embryology of invertebrates, Lankester endorsed Darwin’s theory of evolution. In anthrolopology, his activities included the discovery of flint implements, evidence of early man, within Pliocene sediments, in Suffolk. He was Director of the British Museum of Natural History (1898-1907).
(Alexandre-)Henri Mouhot (Born 15 May 1826; died 10 Nov 1861). (Alexandre-)Henri Mouhot was a French naturalist and explorer of the interior of Siam, Cambodia and Laos (1858-61), he is remembered for his reports of the ruins of Angkor, capital of the ancient Khmer civilization of Cambodia. The location was known to the local population, had been visited by several westerners since the 16th century, but it was Mouhot’s evocative accounts and detailed sketches that popularized the Angkor series of sites with the western public. He drew the attention of western scholars to the many ancient terraces, pools, moated cities, palaces and temples as important archaeological sites. His books were published posthumously as he died in Laos at the young age of 35 from malarial fever on his fourth jungle expedition.
