“ In 1881 Armstrong was appointed director for art at the South Kensington (now Victoria and Albert) Museum in succession to Sir Edward J. Poynter, R.A., and he promptly made his influence felt on the methods of teaching. He held that so rarely were the talents of the craftsman and designer to be found united in the same pupil, that it was the duty of technical schools to recognise the independence of the two capacities, while applying art to industry in every branch of teaching. ”
