(1716-1771) English poet. His ‘Elegy Written in a Country Churchyard’ 1751 is one of the most quoted poems in English. Other poems include ‘Ode on a Distant Prospect of Eton College’, ‘The Progress of Poesy’, and ‘The Bard’; these poems are now seen as the precursors of Romanticism.
A close friend of Horace Walpole at Eton, Gray made a continental tour with him 1739–41, an account of which is given in his vivid letters. His first poem ‘Ode on a Distant Prospect of Eton College’ was published 1747 and again 1748 with ‘Ode on the Spring’ in Robert Dodsley’s (1703–1764) A Collection of Poems By Several Hands.
(1827-1861) British anatomist who compiled a book on his subject, published 1858 with illustrations by his colleague H Vandyke Carter. Through its various editions and revisions, it has remained the definitive work on anatomy.
Gray studied at St George's Hospital, London, where he became demonstrator of anatomy and curator of the St George's Museum.
What is now known as Gray’s Anatomy was based on his own dissections. Unlike other contemporary works on the subject, it was organized in terms of systems, rather than areas of the body. Such sections as neuroanatomy have been greatly enlarged in later editions but the section that deals with, for example, the skeletal system is almost identical to Gray’s original work. It remains a standard text for students and surgeons alike.
(1810-1888) US botanist and taxonomist who became America’s leading expert in the field. His major publications include Elements of Botany 1836 and the definitive Flora of North America 1838, 1843. He based his revision of the Linnaean system of plant classification on fruit form rather than gross morphology.
Gray, born in Saquoit, New York, graduated from medical school but chose botany rather than medicine as his career. A friend and supporter of Charles Darwin, he was one of the founders of the American National Academy of Sciences.
His Manual of Botany 1850 remains the standard reference work on flora east of the Rockies.
SI unit (symbol Gy) of absorbed radiation dose. It replaces the rad (1 Gy equals 100 rad), and is defined as the dose absorbed when one kilogram of matter absorbs one joule of ionizing radiation. Different types of radiation cause different amounts of damage for the same absorbed dose; the SI unit of dose equivalent is the sievert.
Unit of absorbed dose of ionizing radiation equal to 100 rads.
