In 1851 the printing and publishing house of Bradbury and Evans
in Whitefriars, London was employing between 300 and 400 people. 
The following is a list of the people that I have identified during my research as having worked there.
William Bradbury (1799-1869) was one of the founders of the firm of Bradbury and Evans
See William Bradbury.
Frederick Mullett Evans
Frederick Mullet Evans (1804-1870) was one of the founders of the firm of Bradbury and Evans
See Frederick Mullett Evans.
Joseph Aked (1810-1880) was Foreman of the Bindery Department during the printing of Charles Dickens' Pickwick Papers
William Andrews (b.a. 1821) worked for Bradbury and Evans as an Apprentice Machineman in 1842. At a trial at the Old Bailey in April 1842 he was found guilty of the theft of 100 printed copies of Chambers' Edinburgh Journal
value to 4 1/2 d., the goods of William Bradbury and Frederick Mullett Evans, his masters. He was sentenced to be transported to Van Diemen's Land, (Tasmania) for a period of 7 years. His sentence was carried out on 28 March 1845 when he was one of the 220 convicts transported from England to Tasmania on the ship Theresa. 
George Gifford Beard
George Gifford Beard (c1811-1885) was employed as the Superintendent of Machines. He was also publican of the White Swan public house on Fetter Lane, London until October 1847. 
Henry Blunt (b.a.1854) was employed as a Warehouse Boy aged 12 in the 1860s. 
George Brownjohn (b.a.1809-1878) and his son George Albert (1840-1904) were both printers at Bradbury and Evans during the 1860s. George senior, clearly a song lover, entertained his colleagues with 2 songs which were particularly well received by his fellow workers at a staff dinner held at the Prince of Wales Tavern, East Molesey, London in July 1864. 
Charles James Cawte
Charles James Cawte (1832-1907) was employed by Bradbury and Evans as a Compositor. In his recollections of his time spent as a printer there, he spoke about setting the type for work written by William Makepeace Thackeray and Charles Dickens, and had a clear memory of working on the first 2 chapters of Dickens' Little Dorrit
Benjamin Davis (c1807-1864) worked as an Engine Driver at Bradbury and Evans in 1864. He sadly was suddenly taken ill whilst at work, fell over backwards and died instantly. At the inquest into his death it was revealed that he had been suffering from kidney disease which had apparently led to a heart attack. 
John Deas (b.a.1823 in Scotland) was employed by Bradbury and Evans as a Compositor. His son John (b.a.1853) was employed by them as a Warehouse boy, and another son Charles worked for them as a Roller Maker.

He was one of the better known of their employees, being mentioned several times in the letters of Charles Dickens. See Charles Hicks
