Francis Watkins (c.1723-1784)
Francis Watkins is associated chiefly with this type of angle barometer set within a frame. He was apprenticed in 1737 to Nathaniel Adams and became a Freeman of the Spectaclemakers’ Company in 1746. By 1747, Watkins was working in Charing Cross and, from 1763 until 1774, he was in partnership with his former apprentice Addison Smith. By 1775, Watkins was issuing invoices in his own name again and he died in 1784.
