On The Level
John Theophilus Desaguliers (1683 1744) was a French-born British natural philosopher, clergyman, engineer and freemason who was elected to the Royal Society in 1714 as experimental assistant to Isaac Newton, and later popularized Newtonian theories and their practical applications in public lectures. As a Freemason, Desaguliers was instrumental in the establishment of the first Grand Lodge formed in London in 1717 and served as their third Grand Master.
