Francis Watkins (c. 1723-1791) was an eminent figure in the field of mathematical and optical instrument making in mid-eighteenth century London. He apprenticed to Nathaniel Adams in the Spectaclemakers’ Company in 1737 and worked with Edward Scarlett senior and Henry Walder at the Archimedes, Globe and Sun in Soho. After completing his apprenticeship in 1746, he established his business at Sir Isaac Newton’s Head, 4/5 Charing Cross. He took Addison Smith as an apprentice in 1750 and as a partner from 1764 to 1777, signing instruments during this period “Watkins & Smith”. He was succeeded by Jeremiah and William Watkins in 1782. The signature F. Watkins was used between 1746 and 1764, before Watkins’ partnership with Smith, so this set dates to sometime in the mid 18th century.
