Walter Rosenhain, 1875-1934
Walter Rosenhain was born in Melbourne, Australia [hand writen note: Berlin (see DNB 1931-40)], on August 24, 1875. His early education was at Wesley College in that City, from which he passed to Queen’s College in the University of Melbourne, graduating in Physics and Engineering in 1897. He came to England as the holder of an 1851 Exhibition Scholarship, and entered St. John’s College, Cambridge, with the intention of studying civil engineering. He carried out an investigation on steam jets, published in the Proceedings of the Institution of Civil Engineers, but the direction of his life’s work was determined on his arrival, when he consulted Professor (now Sir Alfred) Ewing, as to a suitable subject for research. The study of metals by means of the microscope, following the methods so brilliantly devised by H. C. Sorby, was then making rapid progress in the hands of such men as Roberts-Austen, Stead, Osmond and Arnold. Professor Ewing suggested that it would be of interest to examine how the crystal grains of a metal behaved when they were deformed plastically.
