Sidney Hall was an engraver, cartographer and copperplate printer. Worms and Baynton-Williams state in,'British Map Engravers' that Hall was almost certainly the first engraver to use the new harder steel plates for map work, using plates manufactured by the Jacob Perkins process as early as 1821. He died at the age of forty two and his widow Selina Hall, continued the business, her practice of signing her engravings simply as ,'S.Hall' has caused much confusion among bibliographers.
