After completing his Ph.D. in transition metal chemistry at Imperial College, London, England, Geoff Rayner-Canham has spent his career mainly at the Grenfell Campus of Memorial University, Newfoundland, Canada, together with sabbatical leaves at such diverse places as the Colorado School of Mines and the University of California, Santa Cruz. Being unable to find an inorganic chemistry text which used the concepts to explain the properties and uses of the chemical elements and compounds, he, subsequently joined by Tina Overton, authored Descriptive Inorganic Chemistry. The text is now entering its sixth edition, and has been translated into Spanish, Korean, Japanese, German, Portuguese, and Khmer. Geoff has authored many publications relevant to the teaching of inorganic chemistry, including several on novel aspects of the Periodic Table. Recognition of his contributions to the teaching of chemistry have included the Chemistry Education Award of the Chemical Institute of Canada, and the National Science and Engineering Research Council of Canada PromoScience Award. Researching the life and work of pioneering women chemists is another of his activities, this work resulting in several books co-authored with Marelene Rayner-Canham.
