Hubert Lyman Clark was born 9 January 1870 in Amherst, Massachusetts and died 31 July 1947 in Cambridge, Massachusetts. He was educated at Amherst College and graduated with a bachelor of Arts in 1892 and he received his PhD at Johns Hopkins University in 1897. He was Professor of Biology at Olivet College, Michigan from 1899 to 1905 and he also worked at the Museum of Comparative Zoology, Harvard University from 1905, being curator of echinoderms* from 1910-27. He subsequently became the curator of marine invertebrates and associate professor of zoology at Harvard from 1927.
He held additional appointments in zoology at Stanford University, California 1936 and Hancock University of Southern California in 1946-47. He had an extensive bibliography on echinoderms from at least 1913 to 1946 and his most significant publication was "The Echinoderm Fauna of Australia" in 1946 in which he recorded all known species (including fossils) and discussed the origins and composition of the fauna in relation to adjacent areas.
Lyman had a long standing and extensive association with marine animals of Australia, for he made collecting expeditions to Australia in 1913, 1929 and 1932. In 1947 he was the William Branwhite Clarke Memorial Lecturer and Medallist of the Royal Society of New South Wales in Sydney, thus joining a long parade of former and later scientists honored annually (1878 to the present day) for their contributions to the Natural Sciences (Zoology, Botany and Geology, on a three yearly rotation). In fact Baron Ferdinand von Mueller, the famed Australian Botanist (see paper at this website: "Captains Flat N.S.W. to Cartago, Costa Rica) was an early winner of this award in 1883.
* Echinoderm: Any marine animal of the phylum Echinodermata, having a radiating arrangement of parts and a body wall stiffened by calcareous pieces that may protrude as spines and including the starfishes and sea urchins.
