Benjamin Martin was born in Worplesdon, Surrey, and died in London on 9 February 1782. From a farming background, he began his teaching career in Guildford, before moving to Chichester and then London. He was well known in his own day as an inventor and maker of scientific instruments. Self-taught in mathematics and astronomy, he was an enthusiastic follower of Newton, and at one point even travelled the country giving public lectures on physics. He attempted several compendia of natural sciences and philosophy; his English Dictionary, published in 1749, received a second edition in 1757. His ambitious project to summarize all scientific and philosophical knowledge in fourteen volumes was never finished, though two volumes on philology and two on mathematics were completed, as was a volume of biographies of mathematicians and philosophers, the Biographia Philosophica (1764).
