+||Jesse Ramsden (b. 6 October 1735 ) was a British mathematician, astronomical and scientific instrument maker. His reputation was built on the engraving and design of dividing engines which allowed high accuracy measurements of angles and lengths in instruments. He produced instruments for astronomy that were especially well-known for maritime use where they were needed for the measurement of latitudes and for his surveying instruments which were widely used for cartography and land survey.
