The Easternmost Sheet of George Gauld's Landmark Chart of the Florida Keys.
On the eve of the American Revolution, George Gauld was charged by the British Admiralty with the task of charting the waters off of West Florida. Gauld spent 17 years in the Keys and his precise charts and descriptions provide an in-depth view of the Keys during the period of exploration. He charted the extent of benthic habitat in Florida Keys in the 1760s, including coral reefs, seagrass, and mangroves. He was taken prisoner by Spanish forces during the Siege of Pensacola in 1781.
The chart details the reef and islands, as well as the composition of the ocean floor.
The first edition of the chart was issued in 1790. A second edition was issued in 1820, and later corrected in 1835. The present chart includes an inset showing the Anchorages of Garden Kay from an 1854 American Coast Survey chart and was likely issued sometime thereafter, although we can find no record of any edition of this chart issued after 1835, with the exception of a note in a Susannah Fisher catalog, noting an edition revised to 1847.
All states are extremely rare and, in fact, it seems that the first state of 1790 is actually the most common.
William Faden (1749-1836) was the most prominent London mapmaker and publisher of the late-eighteenth and early-nineteenth centuries. His father, William Mackfaden, was a printer who dropped the first part of his last name due to the Jacobite rising of 1745.
Apprenticed to an engraver in the Clothworkers' Company, he was made free of the Company in August of 1771. He entered into a partnership with the family of Thomas Jeffreys, a prolific and well-respected mapmaker who had recently died in 1771. This partnership lasted until 1776.
Also in 1776, Faden joined the Society of Civil Engineers, which later changed its name to the Smeatonian Society of Civil Engineers. The Smeatonians operated as an elite, yet practical, dining club and his membership led Faden to several engineering publications, including canal plans and plans of other new engineering projects.
Faden's star rose during the American Revolution, when he produced popular maps and atlases focused on the American colonies and the battles that raged within them. In 1783, just as the war ended, Faden inherited his father's estate, allowing him to fully control his business and expand it; in the same year he gained the title "Geographer in Ordinary to his Majesty."
Faden also commanded a large stock of British county maps, which made him attractive as a partner to the Ordnance Survey; he published the first Ordnance map in 1801, a map of Kent. The Admiralty also admired his work and acquired some of his plates which were re-issued as official naval charts.
Faden was renowned for his ingenuity as well as his business acumen. In 1796 he was awarded a gold medal by the Society of Arts. With his brother-in-law, the astronomer and painter John Russell, he created the first extant lunar globe.
After retiring in 1823 the lucrative business passed to James Wyld, a former apprentice. He died in Shepperton in 1826, leaving a large estate.
The British Admiralty has produced nautical charts since 1795 under the auspices of the United Kingdom Hydrographic Office (HO). Its main task was to provide the Royal Navy with navigational products and service, but since 1821 it has also sold charts to the public.
In 1795, King George III appointed Alexander Dalrymple, a pedantic geographer, to consolidate, catalogue, and improve the Royal Navy’s charts. He produced the first chart as the Hydrographer to the Admiralty in 1802. Dalrymple, known for his sticky personality, served until his death in 1808, when he was succeeded by Captain Thomas Hurd. The HO has been run by naval officers ever since.
Hurd professionalized the office and increased its efficiency. He was succeeded by the Arctic explorer Captain William Parry in 1823. By 1825, the HO was offering over seven hundred charts and views for sale. Under Parry, the HO also began to participate in exploratory expeditions. The first was a joint French-Spanish-British trip to the South Atlantic, a voyage organized in part by the Royal Society of London.
In 1829, Rear-Admiral Sir Francis Beaufort was appointed Hydrographer Royal. Under his management, the HO introduced the wind force scale named for him, as well as began issuing official tide tables (1833). It was under Beaufort that HMS Beagle completed several surveying missions, including its most famous voyage commanded by Captain FitzRoy with Charles Darwin onboard. When Beaufort retired in 1855, the HO had nearly two thousand charts in its catalog.
Later in the nineteenth century, the HO supported the Challenger expedition, which is credited with helping to found the discipline of oceanography. The HO participated in the International Meridian Conference which decided on the Greenwich Meridian as the Prime Meridian. Regulation and standardization of oceanic and navigational measures continued into the twentieth century, with the HO participating at the first International Hydrographic Organization meeting in 1921.
During World War II, the HO chart making facility moved to Taunton, the first purpose-built building it ever inhabited. In 1953, the first purpose-built survey ship went to sea, the HMS Vidal. Today, there is an entire class of survey vessels that make up the Royal Navy’s Hydrographic Squadron. The HO began to computerize their charts in the late 1960s and early 1970s. In 1968, the compilation staff also came to Taunton, and the HO continues to work from there today.
