The development of materials science over the last forty years has proceeded at a rapid rate and some of the early experiments and industrial needs which have helped to stimulate the development are discussed. Paper as a material poses many problems which are being tackled in terms of technology, science, and mathematical modelling, and modern methods of analysis will ensure that progress in both the understanding and the technological development of the structure of paper and its mechanical properties continues. It is pointed out that one of the strengths of Dr. Corte’ s many achievements in paper science and technology was to initiate and carry out experiments using relatively simple equipment but to interpret the results using substantial mathematical methods and with a clarity of thought about the physical, chemical, and rheological
implications. Some analogies between the properties of paper and other materials are drawn.
