been Vice President of the Institute of Materials and
President of the Federated European Materials Soci-
eties. Since retirement he has been academic consultant
for a number of institutions both in the UK and over-
seas.
ProfessorR.E.Smallman
After gaining his PhD in 1953, Professor Smallman
spent five years at the Atomic Energy Research Estab-
lishment at Harwell, before returning to the University
of Birmingham where he became Professor of Physi-
cal Metallurgy in 1964 and Feeney Professor and Head
of the Department of Physical Metallurgy and Science
of Materials in 1969. He subsequently became Head
of the amalgamated Department of Metallurgy and
Materials (1981), Dean of the Faculty of Science and
Engineering, and the first Dean of the newly-created
Engineering Faculty in 1985. For five years he was
Vice-Principal of the University (1987 – 92).
He has held visiting professorship appointments at
the University of Stanford, Berkeley, Pennsylvania
(USA), New South Wales (Australia), Hong Kong and
Cape Town and has received Honorary Doctorates
from the University of Novi Sad (Yugoslavia) and
the University of Wales. His research work has been
recognized by the award of the Sir George Beilby Gold
Medal of the Royal Institute of Chemistry and Institute
of Metals (1969), the Rosenhain Medal of the Institute
of Metals for contributions to Physical Metallurgy
(1972) and the Platinum Medal, the premier medal of
the Institute of Materials (1989).
He was elected a Fellow of the Royal Society
(1986), a Fellow of the Royal Academy of Engineer-
ing (1990) and appointed a Commander of the British
Empire (CBE) in 1992. A former Council Member of
the Science and Engineering Research Council, he has
R. J. Bishop
After working in laboratories of the automobile,
forging, tube-drawing and razor blade industries
(1944 – 59), Ray Bishop became a Principal Scientist
of the British Coal Utilization Research Association
(1959 – 68), studying superheater-tube corrosion and
mechanisms of ash deposition on behalf of boiler
manufacturers and the Central Electricity Generating
Board. He specialized in combustor simulation of
conditions within pulverized-fuel-fired power station
boilers and fluidized-bed combustion systems. He then
became a Senior Lecturer in Materials Science at
the Polytechnic (now University), Wolverhampton,
acting at various times as leader of C&G, HNC, TEC
and CNAA honours Degree courses and supervising
doctoral researches. For seven years he was Open
University Tutor for materials science and processing
in the West Midlands. In 1986 he joined the
School of Metallurgy and Materials, University of
Birmingham as a part-time Lecturer and was involved
in administration of the Federation of European
Materials Societies (FEMS). In 1995 and 1997 he
gave lecture courses in materials science at the Naval
Postgraduate School, Monterey, California. Currently
he is an Honorary Lecturer at the University of
Birmingham.
