John Lorimer (1732–1795) was an American surgeon, mathematician, politician and cartographer in the 18th century.
Lorimer served as a surgeon for the British army in North America between 1758 and 1784, participating in both the French and Indian War and the American Revolution. He was a fellow of the Royal College of Physicians of Edinburgh, and author of the book A Concise Essay on Magnetism; with an Account of the Declination and Inclination of the Magnetic Needle; and an Attempt to ascertain the Cause of the Variation thereof, published in 1795.
Experiences in West Florida
Lorimer was a land speculator who owned a thousand acres on Thompson's Creek, Mississippi and a second grant north of Natchez, Mississippi. "Original Grantee/Claimant: Doctor John Lorimer, 2000 acres, Walnut Hills. Patent date: May 6, 1776."
At the time Pensacola surrendered to the Spanish, Lorimer was listed as a magistrate.
In 1778, Peter Chester, Governor of the British Colony of West Florida, appointed Lorimer as a "Botanist" for the Province of West Florida.
In 1774, Lorimer went on an expedition up the Mississippi River to map the western boundary of the Colony of West Florida from the mouth of the Yazoo River to Bayou Manchac. He went along with George Gauld and Thomas Hutchins not only because he was a surgeon, but also because his mathematical skills for determining latitude and longitude were greatly desired. "The latitudes of the entrance of the river Yazou, Natchez, Manchac and some other parts of the river were taken by Doctor Lorimer, which were a great correction and satisfaction in laying down this plan." Afterwards, Thomas Hutchins would publish several publications about his experiences and observations in West Florida. He used and re-published much of the written materials and charts produced by Lorimer, Gauld and Lieutenant Philip Pittman under his own name. So would the colonial naturalist Bernard Romans. Even in those days of loose copyright laws, using other people's creations was well known. In correspondence with General Thomas Gage, General Frederick Haldimand sent him some of Gauld's maps along with his report, with the proviso that no one else should copy the maps drawn by Gauld.
