He moved to London in the late 1800s to join the design firm, The Silver Studio, and it was here that he began working with Liberty & Co. In 1899 Knox designed the first series of silverware for their Cymric line, a collection with strong Celtic influence which was integral to Liberty's successful contributions to Celtic Revival, where in Italy, the period is still referred to as 'Stile Liberty'. As Liberty's chief designer, between 1900 and 1904, Knox is thought to have created over seven hundred jewellery designs. Knox undoubtedly shaped the Celtic Revival in the United Kingdom, and his pioneering and prolific work bridged the Arts and Crafts Movement, Celtic Revival, Art Nouveau, and Modernism.
