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.").

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).
