T. RiderIt is possible that Rider was the son of Thomas Ryder (1746-1810), the engraver who specialized in stipple work and was employed by Boydell, the manager of the Shakespeare Gallery.
Several addresses of Rider (all in London) are known from his trade labels. No. 1 gives the address 8 Charles Street, but for the period 1784-1801 the relevant rate books (for St Paul's, Covent Garden) do not list Rider's name. On the other hand, the Harleian transcripts of the registers for this parish show many mentions of the name Rider. One record (1799) lists a T. Rider as a witness to a wedding and states that a son, Thomas, of Thomas and Ann Rider, was christened in that year. Either of these references might indicate T. Rider (or Ryder) the silhouette artist.
