The Dial was an American magazine published intermittently from 1840 to 1929.
 In its first form, from 1840 to 1844, it served as the chief publication of the Transcendentalists.
 In the 1880s it was revived as a political magazine.
 From 1920 to 1929 it was an influential outlet for modernist literature in English.
Punch; or, The London Charivari was a British weekly magazine of humour and satire established in 1841 by Henry Mayhew and engraver Ebenezer Landells.

William Mudford (8 January 1782 – 10 March 1848), was a British writer, essayist, translator of literary works and journalist.
 He also wrote critical and philosophical essays and reviews.
 His 1829 novel "The Five Nights of St. Albans: A Romance of the Sixteenth Century" received a good review from John Gibson Lockhart, an achievement which was considered a rare distinction.
 Mudford also published short fictional stories which were featured in periodicals such as "Blackwood's Edinburgh Magazine", "Fraser's Magazine", and "Bentley's Miscellany".
 His short story "The Iron Shroud", about an iron torture chamber which shrinks through mechanical action and eventually crushes the victim inside, was first published in August 1830 by "Blackwood's Edinburgh Magazine", and later republished separately in 1839 and 1840 with the subtitle ""Italian Revenge"".
 Edgar Allan Poe is considered to have been influenced by "The Iron Shroud" when he wrote "The Pit and the Pendulum" having got his idea for the shrinking chamber from Mudford's story.
 Mudford was born in London, where his father made a living as a shopkeeper in Piccadilly.
 He was influenced by John Milton, Joseph Addison, Samuel Johnson, William Cowper, William Collins, Mark Akenside, Thomas Gray, and Oliver Goldsmith.

 The management of the Press was taken over in 1840 by the founder's nephew Charles Whittingham II (1795–1876).
 The name was first used in 1811, and the Press continued to operate until 1962.
 C. Whittingham I gained notoriety for his popularly priced classics, but the Chiswick Press became very influential in English printing and typography under C. Whittingham II who, most notably, published some of the early designs of William Morris.
 The Chiswick Press deserves conspicuous credit for the reintroduction of quality printing into the trade in England when in 1844 it produced "The Diary of Lady Willoughby".

 Towards the end of her life (cut short by cancer), she moved to America, where she opened a consulting business whose clients included the actor Laura Keene.
