Joseph Jackson, who shared with the Caslons the favour of the London booksellers, was one of two apprentices formerly in the employ of William Caslon II. Some dispute arose in the foundry about the price of certain work, and Joseph Jackson and Thomas Cottrell, having acted as ringleaders in the movement, were dismissed, and being thrown on their own resources, set up a foundry of their own in Nevil's Court, Fetter Lane. Of the two Jackson proved far the more skilful, but seems to have been of a roving disposition. After working for a year or two with Cottrell he went to sea, leaving Cottrell to carry on the business alone. This he did with a fair measure of success, though his foundry was never at any time a large one. After a few years' absence Jackson returned to England in 1763, and again turned his attention to letter-cutting, serving for a time under his old partner Cottrell; but having obtained the services and, what was of more value, the pecuniary help of two of Cottrell's workmen, he set up for himself, and quickly took a foremost place in the trade. Among his most successful work was a fount of English 'Domesday,' for the Domesday Book published by order of Parliament in 1783, which was preferred to that cut by Cottrell for the same purpose. Jackson also cut a fount for Dr. Woide's facsimile of the Alexandrian Codex with great success. But perhaps his most successful effort was the two-line English which he cut for Macklin's edition of the Bible, begun in 1789. At the time of his death in 1792 he was at work upon a fount of double pica for Bowyer's edition of Hume's _History of England_. After his death his foundry was purchased by William Caslon III. Both Macklin's Bible and Hume's _History_ were printed at the press of Thomas Bensley in Bolt Court, Fleet Street. As a printer of sumptuous books Bensley had only one rival, William Bulmer, who is generally accorded the first place. But Bensley was certainly earlier in the field. His work was quite equal to that of Bulmer, and, apart from this, the world owes more to his enterprise than it has ever yet acknowledged. Thomas Bensley was the son of a printer in the Strand, and in 1783 he succeeded to the business of Edward Allen in Bolt Court, a house adjoining that in which Johnson had lived. He at once turned his attention to printing as a fine art. Dibdin, in his _Bibliographical Decameron_ (vol. ii. p. 397, etc.), gives a list of the works printed by Bensley, and says that he began with a quarto edition of Lavater's _Physiognomy_ in 1789, following this up with an octavo edition of Allan Ramsay's _Gentle Shepherd_ in 1790. In this list, however, Dibdin has omitted the folio edition of Bürger's poem _Leonora_, printed by Bensley in 1796, with designs by Lady Diana Beauclerc. In 1797 he printed a very beautiful edition of Thomson's _Seasons_, in royal folio, with engravings by Bartolozzi and P. W. Tomkins from pictures by W. Hamilton.
