[441] William Frend (1757-1841), whose daughter Sophia Elizabeth became De
Morgan's wife (1837), was at one time a clergyman of the Established
Church, but was converted to Unitarianism (1787). He came under De Morgan's
definition of a true paradoxer, carrying on a zealous warfare for what he
thought right. As a result of his _Address to the Inhabitants of Cambridge_
(1787), and his efforts to have abrogated the requirement that candidates
for the M.A. must subscribe to the thirty-nine articles, he was deprived of
his tutorship in 1788. A little later he was banished (see De Morgan's
statement in the text) from Cambridge because of his denunciation of the
abuses of the Church and his condemnation of the liturgy. His eccentricity
is seen in his declining to use negative quantities in the operations of
algebra. He finally became an actuary at London and was prominent in
radical associations. He was a mathematician of ability, having been second
wrangler and having nearly attained the first place, and he was also an
excellent scholar in Latin, Greek, and Hebrew.

[442] George Peacock (1791-1858), Fellow of Trinity College, Cambridge,
Lowndean professor of astronomy, and Dean of Ely Cathedral (1839). His tomb
may be seen at Ely where he spent the latter part of his life. He was one
of the group that introduced the modern continental notation of the
calculus into England, replacing the cumbersome notation of Newton, passing
from "the _dot_age of fluxions to the _de_ism of the calculus."

[443] Robert Simson (1687-1768); professor of mathematics at Glasgow. His
restoration of Apollonius (1749) and his translation and restoration of
Euclid (1756, and 1776--posthumous) are well known.

[444] Francis Maseres (1731-1824), a prominent lawyer. His mathematical
works had some merit.

[445] These appeared annually from 1804 to 1822.

[446] Henry Gunning (1768-1854) was senior esquire bedell of Cambridge. The
_Reminiscences_ appeared in two volumes in 1854.

[447] John Singleton Copley, Baron Lyndhurst (1772-1863), the son of John
Singleton Copley the portrait painter, was born in Boston. He was educated
at Trinity College, Cambridge, and became a lawyer. He was made Lord
Chancellor in 1827.

[448] Sir William Rough (c. 1772-1838), a lawyer and poet, became Chief
Justice of Ceylon in 1836. He was
