William Morris was an influential figure in the English Arts and Crafts Movement. As a leading manufacturer and decorator, he exercised a profound influence on industrial design and interior decoration in the late nineteenth century. Morris was also a shareholder in Devon Great Consuls, a mine that became the world’s largest source of arsenic.
In 2003, a Scottish bio-geochemist identified the presence of arsenic green pigments in a sample of Trellis wallpaper, one of Morris’s earliest and most popular patterns.
