After establishing his own school as a young man, Martin started to write books on natural philosophy aimed at a general audience, thus setting into motion a prolific career during which he published works on natural philosophy, theology, mathematics, language and geography. By 1738, Martin’s central interest had become optics, for which he produced wooden and cardboard microscopes. In 1756 he began trading as an optician in London, also producing and selling scientific instruments and globes at his premises by ‘The Hadleys Quadrant and Visual Glasses’.
An engraved likeness “from an Original Portrait” was found in the ‘Gentleman’s Magazine’ of 1785, showing Martin in a wig, cravat, waistcoat and jacket (but no glasses!) in three-quarter perspective. It is the same portrait that appears in Wilkes’ encyclopedia, reengraved by Robert Page, with an additional illustration of his shop sign beneath the oval frame.
