P. E. Gretener

Peter Gretener was educated in Switzerland, where he obtained a PhD in geophysics from the Swiss Federal Institute of Technology in Zürich. After working in industry in Calgary, Houston and the far North for over a decade, he entered the ranks of academe at the University of Calgary. There, he spent some thirty years as a professor of Geology and Geophysics who sought to leave a mark on his students--"They should love me or hate me, just not be indifferent." Beyond rocks, Gretener was interested in mankind's interactions with planet Earth.

Professor Gretener died in 2008. The Vanishing of a Species? is published posthumously from a manuscript and papers uncovered after his death.
