DEFENCE SCIENTIST WINS DOCTORATE

Statement by the Minister for Supply, The Hon. Alan S, Hulme

The Minister for Supply, The H0n. Alan S. Hulme, announced  to-day that a member of the Department of Supply’s Defence  Standards Laboratory in Sydney had received Melbourne University’s  highest degree for scientific achievement.

The University granted this recognition to metallurgist  Leonard Ernest SAMUELS, 37, of 42, Marcella Street, Kingsgrove,  Sydney, and formerly of Melbourne, whose earlier awards include

the American Society for Metals, Blue Ribbon Award and the  David Syme Research Prize. The Degree of Doctor of Science  conferred on him to-day was awarded for researches into the  effects of grinding and polishing operations on the structure

at metal surfaces.

Dr. Samuel’s work at Defence Standards Laboratories, N.S.W. Branch, on metal-finishing problems led him to question

earlier ideas and theories about the complicated events which

occur on the atomic scale at metal surfaces during the cutting

and polishing operations. He also sought answers through  fundamental studies using some of the newer and more powerful  methods such as phase-contrast microscopy, electron-miscroscopy

and electron diffraction. Many of his results have been published

in overseas journals and have gained him wide recognition both  in Australia and overseas as one of the world’s leading  Metallographers.
