Document 6: London Labour and the London Poor: London Labour and the London Poor is a work of Victorian journalism by Henry Mayhew. In the 1840s he observed, documented, and described the state of working people in London for a series of articles in a newspaper, the "Morning Chronicle", that were later compiled into book form.
Document 7: Age of Enlightenment: In France, the established men of letters (gens de lettres) had fused with the elites (les grands) of French society by the mid-18th century. This led to the creation of an oppositional literary sphere, Grub Street, the domain of a "multitude of versifiers and would-be authors". These men came to London to become authors, only to discover that the literary market simply could not support large numbers of writers, who, in any case, were very poorly remunerated by the publishing-bookselling guilds.
Document 8: Great Plague of London: People began to be alarmed. Samuel Pepys, who had an important position at the Admiralty, stayed in London and provided a contemporary account of the plague through his diary. On 30 April he wrote: ``Great fears of the sickness here in the City it being said that two or three houses are already shut up. God preserve us all! ''Another source of information on the time is a fictional account, A Journal of the Plague Year, which was written by Daniel Defoe and published in 1722. He had been only six when the plague struck but made use of his family's recollections (his uncle was a saddler in East London and his father a butcher in Cripplegate), interviews with survivors and sight of such official records as were available.
Document 9: Barnaby Rudge: "Barnaby Rudge" was the fifth of Dickens' novels to be published. It had initially been planned to appear as his first, but changes of publisher led to many delays, and it first appeared in serial form in the "Clock" from February to November 1841.
Document 10: Charles Dickens: The Posthumous Papers of the Pickwick Club (Known as ``The Pickwick Papers '') (Monthly serial, April 1836 to November 1837)
Document 11: London: London has been the setting for many works of literature. The literary centres of London have traditionally been hilly Hampstead and (since the early 20th century) Bloomsbury. Writers closely associated with the city are the diarist Samuel Pepys, noted for his eyewitness account of the Great Fire, Charles Dickens, whose representation of a foggy, snowy, grimy London of street sweepers and pickpockets has been a major influence on people's vision of early Victorian London, and Virginia Woolf, regarded as one of the foremost modernist literary figures of the 20th century.
Document 12: Oliver Twist: The novel was originally published in monthly instalments in the magazine Bentley's Miscellany, from February 1837 to April 1839. It was originally intended to form part of Dickens's serial, The Mudfog Papers. George Cruikshank provided one steel etching per month to illustrate each instalment. The novel first appeared in book form six months before the initial serialisation was completed, in three volumes published by Richard Bentley, the owner of Bentley's Miscellany, under the author's pseudonym, "Boz". It included 24 steel-engraved plates by Cruikshank.
Document 13: Charles Dickens: Dickens's literary success began with the 1836 serial publication of The Pickwick Papers. Within a few years he had become an international literary celebrity, famous for his humour, satire, and keen observation of character and society. His novels, most published in monthly or weekly instalments, pioneered the serial publication of narrative fiction, which became the dominant Victorian mode for novel publication. Cliffhanger endings in his serial publications kept readers in suspense. The instalment format allowed Dickens to evaluate his audience's reaction, and he often modified his plot and character development based on such feedback. For example, when his wife's chiropodist expressed distress at the way Miss Mowcher in David Copperfield seemed to reflect her disabilities, Dickens improved the character with positive features. His plots were carefully constructed, and he often wove elements from topical events into his narratives. Masses of the illiterate poor chipped in ha'pennies to have each new monthly episode read to them, opening up and inspiring a new class of readers.
Document 14: London: London's buildings are too diverse to be characterised by any particular architectural style, partly because of their varying ages. Many grand houses and public buildings, such as the National Gallery, are constructed from Portland stone. Some areas of the city, particularly those just west of the centre, are characterised by white stucco or whitewashed buildings. Few structures in central London pre-date the Great Fire of 1666, these being a few trace Roman remains, the Tower of London and a few scattered Tudor survivors in the City. Further out is, for example, the Tudor period Hampton Court Palace, England's oldest surviving Tudor palace, built by Cardinal Thomas Wolsey c.1515.
Document 15: Pub: Many of London's pubs are known to have been used by famous people, but in some cases, such as the association between Samuel Johnson and Ye Olde Cheshire Cheese, this is speculative, based on little more than the fact that the person is known to have lived nearby. However, Charles Dickens is known to have visited the Cheshire Cheese, the Prospect of Whitby, Ye Olde Cock Tavern and many others. Samuel Pepys is also associated with the Prospect of Whitby and the Cock Tavern.
