Abstract
IT is a grief and a shock to me, on returning from a holiday abroad, to read of the death of Walter Rosenhain. I have had many pupils, but none more gifted with the imaginative insight of the discoverer, more discriminating in criticism, or more skilful in the technique of the experimentalist. He came to me, in the late 'nineties, with a research scholarship from the University of Melbourne, when I was professor of mechanism at Cambridge, and asked me to suggest a piece of research which he might undertake in my laboratory. At that time Roberts-Austen, Arnold, J. E. Stead, Osmond and others were applying to metallurgical analysis the microscopic methods which had been initiated by Sorby in his earlier study of metals, and it was beginning to be recognised, somewhat vaguely, that the irregular grains which a polished metal revealed in the microscope were crystals the boundaries of which had interfered with one another in the process of crystal growth. I suggested to Rosenhain that this opened up a good field, and that it would be interesting to see what happened when a plastic metal was overstrained. The supposed crystal grains must alter their form, but how?
