Owen, Sir Richard (1804-92): was born at Lancaster, and educated at the
local Grammar School, where one of his schoolfellows was William Whewell,
afterwards Master of Trinity. He was subsequently apprenticed to a surgeon
and apothecary, and became deeply interested in the study of anatomy. He
continued his medical training in Edinburgh and at St. Bartholomew's
Hospital in London. In 1827 Owen became assistant to William Clift (whose
daughter Owen married in 1835), Conservator to the Hunterian Museum of the
Royal College of Surgeons. It was here that he became acquainted with

the Pearly Nautilus" placed the author "in the front rank of anatomical
monographers." On Clift's retirement, Owen became sole Conservator to the
Hunterian Museum, and was made first Hunterian Professor of Comparative
Anatomy and Physiology at the Royal College of Surgeons. In 1856 he
accepted the post of Superintendent of the Natural History department of
the British Museum, and shortly after his appointment he strongly urged the
establishment of a National Museum of Natural History, a project which was
eventually carried into effect in 1875. In 1884 he was gazetted K.C.B.
