Ken Kershaw’s Plating The More Distinctive Re-entries In The Half Cent Maple Leaf Stamp I. Plating Criteria And Detailed Descriptions Of The First And Second Printings is the latest BNAPS handbook. In this first of three volumes the author has used today’s technology to the utmost to continue the BNAPS tradition of providing information freely to collectors. Ken’s work on the Half Cent Leaf follows closely on his previous major effort (with Roger Boisclair), the four book series ‘Plating The Canadian Xmas Stamp Of 1898’.Ken Kershaw was born in England and became fascinated by plants at an early age. He graduated from Manchester University with a B Sc degree in Botany in 1952. After military service he went on to a Ph. D. degree working on pattern in vegetation, and was appointed lecturer in Plant Ecology at Imperial College London in 1957. He was seconded to Ahmadu Bello University in northern Nigeria for two years. On his return to Imperial College he became involved with lichen ecology, particularly in alpine and arctic areas, in addition to his work on computer modelling and data analysis. He obtained his D Sc in 1965 and was appointed Professor at McMaster University, Hamilton in 1969. His research was then devoted heavily to the ecology of the Canadian low arctic and northern boreal forest areas, and in 1982 he was elected a fellow of the Royal Society of Canada. He is the author of several university texts. Ken’s passion for wild plants has been transferred to Canadian philately. He sees his plating work simply as the “taxonomy of bits of paper” and after a lifetime of plant taxonomy finds it a fairly straightforward and fascinating hobby.
