William Walker(1791-1867), Photographer, engraver and publisher
Artist associated with 119 portraits
Walker was initially apprenticed to Edinburgh engraver E. Mitchell before moving to London and studying line engraving with James Stewart, stipple engraving with Thomas Woolnoth and mezzotinting with Thomas Lupton. In 1819, he returned to Scotland and was employed to make the engraving of Sir Henry Raeburn's equestrian portrait of the fourth earl of Hopetoun (1821), which established his reputation. He engraved a number of portraits after Raeburn, notably those of Sir Walter Scott and Raeburn himself, which are often cited as among the finest examples of stipple work ever produced.
