COLBURN, HENRY (d. 1855), British publisher, obtained his earliest
experience of bookselling in London at the establishment of W. Earle,
Albemarle Street, and afterwards as an assistant at Morgan's Library,
Conduit Street, of which in 1816 he became proprietor. He afterwards
removed to New Burlington Street, where he established himself as a
publisher, resigning the Conduit Street Library to Messrs Saunders &
Otley. In 1814 he originated the _New Monthly Magazine_, of which at
various times Thomas Campbell, Bulwer Lytton, Theodore Hook and Harrison
Ainsworth were editors. Colburn published in 1818 _Evelyn's Diary_, and
in 1825 the _Diary of Pepys_, edited by Lord Braybrooke, paying L2200
for the copyright. He also issued Disraeli's first novel, _Vivian Grey_,
and a large number of other works by Theodore Hook, G. P. R. James,
Marryat and Bulwer Lytton. In 1829 Richard Bentley (q.v.) was taken into
partnership; and in 1832 Colburn retired, but set up again soon
afterwards independently in Great Marlborough Street; his business was
taken over in 1841 by Messrs Hurst & Blackett. Henry Colburn died on the
16th of August 1855, leaving property to the value of L35,000.

COLBURN, ZERAH (1804-1840), American mathematical prodigy, was born at
Cabot, Vermont, on the 1st of September 1804. At a very early age he
developed remarkable powers of calculating with extreme rapidity, and in
1810 his father began to exhibit him. As a performing prodigy he visited
Great Britain and France. From 1816 to 1819 he studied in Westminster
school, London. After the death of his father in 1824 he returned to
America, and from 1825 to 1834 he was a Methodist preacher. As he grew
older his extraordinary calculating powers diminished. From 1835 until
his death, on the 2nd of March 1840, he was professor of languages at
the Norwich University in Vermont. He published a _Memoir_ of his life
in 1833.

His nephew, also named ZERAH COLBURN (1832-1870), was a well-known
mechanical engineer; the editor successively of the _Railroad Advocate_,
in New York, _The Engineer_, in London, and _Engineering_, in London;
and the author o
