Rigobert Bonne; 1729-1793.

Bonne, a trained mathematician, was appointed Hydrographer to the King. He took over the responsibility of the French Hydrographic Institute ("Dépôt de la Marine") after the death of Bellin in 1772. This position enabled Bonne to pre-eminent access to prime mapping data, which he could use successfully for his own private business interests.
He followed in the steps of the French school of cartographic minutiae and geographic accuracy. As such he produced, often in collaboration with other mapmakers, a large number of excellent sea charts.
His name is generally associated with a type of equal area projection he often used after 1757.
Of note, his participation (with Janvier and Rizzi-Zannoni) to Jean Lattré's 1762 "Atlas Moderne". But he is most well known for the wealth of maps he prepared for Guillaume Thomas François Raynal's "Atlas de toutes les parties connues du globe terrestre" (1780), and also for Nicolas Desmaret*'s "Atlas Encyclopédique" (1787, re-issued in 1827).

* Desmaret: of engineering fame for the first recorded design of an undersea tunnel between France and England in 1751.

Carte de la Louisiane, et de la Floride.

This map (8 5/16" X 12 5/8") was produced for the "Atlas de toutes les parties connues du globe terrestre".
It is rather unusual: the coastal delineation is quite correct (specially for the Louisiana part which the French knew very well after forty five years of presence in New Orleans, founded in 1718), but the states lines are quite erratic and unlike the trademark professional precision of Bonne*. On the Atlantic side, the Georgia Florida border does not follow the St Marys river, The western most Florida border is not following the Iberville river. The state line between the two Carolinas is pure fantasy. Louisiane still extends deeply east of the Mississippi (french sovereignty over that area was terminated by the first treaty of Paris in 1763). And finally: no mention is made of the two Floridas. Under the British rule (between 1763 and 1783), Florida was partitioned into West (capital city: Pensacola) and East (capital city: St Augustine).
Note also the profound ignorance of the inland geography of the Florida peninsula (strange shape and location for the Okeechobee lake, here named St Esprit, or Holy Ghost).

* Said state lines are not important in 1780 (both Georgia and Florida belonged to England)...but after the Revolutionary War ended, Georgia fell with the newly established USA while Florida was back under the control of Spain....imprecision of borders will have some unfortunate consequences..
