William Morris’ designs still held sway in England. The most significant Art Nouveau contribution was from Aubrey Beardsley with his black and white stuff. Beardsley had five years of incredible work then died at 26 of TB (consumption). Mort D’Arthur made him famous at 20. Morris hated Mort D’Arthur so much that he contemplated suing Beardsley over it. In 1900, Walter Crane wrote a popular book, Line & Form, that analyzed design geometrically.
