- The Hadleys Quadrant and Visual Glasses, near Crane Court, in Fleet Street, London
- Scientific lecturer, writer, optician and instrument maker.
After establishing a school in Chichester during his late twenties, Martin began to write books on natural philosophy aimed at a general audience. This was the start of a prolific writing career covering topics such as natural philosophy, theology, mathematics, language and geography.
By 1738, Martin had taken an interest in optics and produced a number of wood and cardboard microscopes. During this period he also started to present lectures and demonstrations on experimental philosophy to audiences in Reading, Bristol, Bath and London. He later spent a decade touring numerous towns and cities across southern England and the Midlands.
In 1756 he returned to London and began trading as an optician in response to his own need for reading glasses. He also produced scientific instruments and globes and became an established retailer and wholesaler in the instrument trade, while still continuing to produce many written works. Despite this wide-ranging business portfolio, Martin was declared bankrupt in January 1782 and died a few weeks later.
