Hooker, Sir William Jackson (1785-1865): was called to the Chair of Botany at Glasgow in 1820, where by his success as a teacher he raised the annual fees from 60 pounds to 700 pounds. In 1841 he became Director of the Royal Botanic Gardens at Kew, which under his administration increased enormously in activity and importance. His private Herbarium, said to be "by far the richest ever accumulated in one man's lifetime," formed the nucleus of the present collection. He produced, as author or editor, about a hundred volumes devoted to Botany ("Dict. of Nat. Biog."). -Herbarium at Kew belonging to. -letters to. -mentioned.
Hopkins, William, F.R.S. (1793-1866) entered Peterhouse, Cambridge, at the age of thirty, and in 1827 took his degree as seventh wrangler. For some years Hopkins was very successful as a mathematical tutor; about 1833 he began to take a keen interest in geological subjects, and especially concerned himself with the effects of elevating forces acting from below on the earth's crust. He was President of the Geological Society in 1851 and 1852 ("Quart. Journ. Geol. Soc." Volume XXIII., page xxix, 1867). -Article in "Fraser's Magazine." -on elevation and earthquakes. -on mountain-building. -researches in physical geology. -mentioned.
Horner, Leonard, F.R.S. (1785-1862): was born in Edinburgh, at the age of twenty-one he settled in London, and devoted himself more particularly to Geology and Mineralogy, returning a few years later to Edinburgh, where he took a prominent part in founding the School of Art and other educational institutions. In 1827 Mr. Horner was invited to occupy the post of Warden in the London University,a position which he resigned in 1831; he also held for some years an Inspectorship of Factories. As a Fellow of the Royal Society, Mr. Horner "took an active part in bringing about certain changes in the management of the Society, which resulted in limiting to fifteen the number of new members to be annually elected..." In 1846 Horner was elected President of the Geological Society; and in 1860 he again presided over the Society, to the interests of which he had long devoted himself.
