London-based THOMAS RIDER (dec. after 1793) was one of the earlier profilists crafting works on glass in the City. Also producing work on plaster and card his extant output is relativly rare and occasionaly evidences notably individual methods of presentation. Between 1791-1793 Rider entered into a partnership with jeweller William Bazing (1762-1812) after which he disappears from definative records.
Though Mckechnie theorised Rider was possibly the son of engraver Thomas Ryder (1746-1810), current strands of research strongly suggest he was a 'Glass-maker'.
