Important Revolutionary War Period map of Lake Champlain, depicting William Brassier's survey of teh region during the French & Indian War.
This excellent large detailed chart of Lake Champlain was based on the survey made by Brassier during 1758 and 1759, while he was in the employ of John Montressor as both a surveyor and draughtsman. A number of the names have been changed, Ticonderoga was formerly Fort Carillon, Fort George and Fort William now feature as does Lake George (named after the British monarch in 1755).
Brassier's survey remained in manuscript form until the outset of the American Revolution. It was then engraved and first issued in Jeffery's American Atlas. Shortly afterwards the second state was published in Sayer and Bennett's American Military Pocket Atlas - the so-called Holster Atlas.
Offered here is the second state, which has been updated in late 1776 to show the English and American Fleets off the Isle of Valcour on October 11, their movements down the river, and a second engagement off Crown Point on October 13, with lettered references. The inset illustrates America's first naval battle, in which General Benedict Arnold, though forced back down the lake, was able to delay the British attempt to descend to the Hudson for that year. No mention, of course, is made of Ethan Allen's taking of Fort Ticonderoga in 1775.
Robert Sayer (ca. 1724-1794) was a prominent London map publisher. Robert’s father was a lawyer, but his older brother married Mary Overton, the widow of prominent mapmaker Philip Overton and the proprietor of his shop after his death. Mary continued the business for roughly a year after her marriage and then, in early 1748, it passed to Robert. Robert became a freeman of the Stationers’ Company later that year; his first advertisement as an independent publisher was released in December.
Sayer benefited from Overton’s considerable stock, which included the plates of John Senex. In the 1750s, Sayer specialized in design books and topographical prints, as well as comic mezzotints. In 1753, he, along with John Roque, published a new edition of Thomas Read’s Small British Atlas, the first of several county atlases that Sayer would publish.
Sayer’s business continued to grow. In 1760 he moved further down Fleet Street to larger premises at 53 Fleet Street. In 1766, he acquired Thomas Jefferys’ stock when the latter went bankrupt. In 1774, he entered into a partnership with John Bennett, his former apprentice. The pair specialized in American atlases, based on the work of Jefferys. They also began publishing navigational charts in the 1780s and quickly became the largest supplier of British charts in the trade.
Bennett’s mental health declined, and the partnership ended in 1784. As Sayer aged, he relied on his employees Robert Laurie and James Whittle, who eventually succeeded him. He spent more and more time at his house in Richmond. In 1794, he died in Bath.
John Bennett (fl. 1760-d. 1787) was a London printer best known for his role in the successful partnership of Sayer & Bennett. In 1760, Bennett became a servant of Robert Sayer (ca. 1724-1794), the prominent print and map seller, and was apprenticed to him in 1765. In 1774, Bennett became a free journeyman and entered into a partnership with Sayer. They issued joint advertisements and publications. In 1777, Bennett owned 1/3 share in the business. The partnership was likely to continue fruitfully, but in 1781 Bennett began to show signs of mental illness. In 1783, he was admitted to an asylum for nine months and, in 1784, Sayer filed papers to dissolve their business partnership. Bennett died in 1787.
