Lhuyd was born in 1660, in
Loppington,
Shropshire,
England, the illegitimate son of Edward Llwyd or Lloyd of Llanforda,
Oswestry, and Bridget Pryse of
Llansantffraid, near
Talybont,
Cardiganshire, in 1660. His family belonged to the gentry of southwest Wales. Though well established, the family was not wealthy. His father experimented with agriculture and industry in a manner that impinged on the new science of the day. The son attended and later taught at
Oswestry Grammar School, and in 1682 went up to
Jesus College, Oxford, but dropped out before
graduation. In 1684, he was appointed to assist
Robert Plot,
Keeper of the
Ashmolean Museum (which at that time was in
Broad Street), and became the second Keeper himself in 1690, holding the post until his death in 1709. While working at the Ashmolean Museum, Lhuyd travelled extensively. A visit to
Snowdonia in 1688 allowed him to compile for
John Ray's a list of
flora local to that region. After 1697, Lhuyd visited every county in Wales, then travelled to
Scotland,
Ireland,
Cornwall,
Brittany and the
Isle of Man. In 1699, it became possible through funding from his friend
Isaac Newton for him to publish the first catalogue ever of
fossils, his . These had been collected in England, mostly in Oxford, and are now held in the Ashmolean. Lhuyd received a
MA honoris causa from the University of Oxford in 1701 and a fellowship of the
Royal Society in 1708. In 1696, Lluyd transcribed much of the Latin inscription on the 9th-century
Pillar of Eliseg near
Valle Crucis Abbey,
Denbighshire. The inscription subsequently became almost illegible due to
weathering, but Lhuyd's transcript seems to have been remarkably accurate. Lhuyd was also responsible for the first scientific description and naming of what we would now recognize as a
dinosaur: the
sauropod tooth Rutellum impicatum.
trilobite O. debuchii The first written record of a
trilobite was by Lhuyd in a letter to
Martin Lister in 1688 and published (1689) in his
Lithophylacii Britannici Ichnographia. It is a fleeting mention and he simply identifies his find as a "skeleton of some flat fish". The trilobite is nowadays identified as
Ogygiocarella debuchii Brongniart, 1822. ==Pioneering linguist==
