Thomas Campbell (poet) in the context of Battle of the Baltic (poem)

Steel engraving is a technique for printing illustrations on paper using steel printing plates instead of copper, the harder metal allowing a much longer print run before the image quality deteriorates. It has been rarely used in artistic printmaking, although it was much used for reproductions in the 19th century. Steel "engraving", in fact technically mostly using etching, was introduced in 1792 by Jacob Perkins (1766–1849), an American inventor, for banknote printing. When Perkins moved to London in 1818, the technique was adapted in 1820 by Charles Warren and especially by Charles Heath (1785–1848) for Thomas Campbell's Pleasures of Hope, which contained the first published plates engraved on steel. The new technique only partially replaced the other commercial line engraving techniques of that time such as wood engraving, copper engraving and later lithography.

The Clarence Club, formerly known as the Literary Union Club, was a gentlemen's club founded in 1826, as a socially exclusive dining society that met in Conduit Street, Mayfair, by the poet Thomas Campbell, with the objective of the facilitation of social connections between those with an interest in the arts, philosophy, finance, trade, business, and science. Most of its members were English, but, originally, it included a significant core of members of Scottish descent. It is notable for its prohibition, then radical, of the extension of membership to any member of the press.

In 1829, it occupied premises in Regent Street, renamed itself the Literary Union Club, and revised its membership statutes to make it less exclusive. It had over 700 members by 1831. After membership became too numerous, it subsequently renamed itself again, as the Clarence Club, occupied 12 Waterloo Place, Pall Mall and limited its membership to 600.

The Anglo Polish Society (APS) is a British organisation of solidarity with Poles, founded on February 25, 1832 in the United Kingdom, by the Scottish poet Thomas Campbell and German lawyer Adolphus Bach, as the Literary Association of the Friends of Poland. Although the creation of the organisation was the result of deep pro-Polish sympathies of Campbell and the whole contemporary British public opinion, Prince Adam Jerzy Czartoryski did attend a dinner for the association, in Edinburgh 1835 along with Count Zamoyski.
