J. J. Hilder’s landscape watercolours were simply composed and highly prized for their subjective vision and sophisticated colour harmonies. Hilder’s handling of broad washes on textured papers and atmospheric effects of light, haze and mist proved so influential on other watercolourists (amateurs in particular) that in the 1920s George Lambert scathingly described such work as belonging to the ‘blotting-paper school.’ Hilder’s work sold very well during his lifetime and his influence was reinforced by a tribute exhibition held in 1916 and the publication of a major monograph on his work in the same year.
