Karl K. Turekian (1927–2013)



Karl K. Turekian, geochemist and educator extraordinaire, passed away on 15 March 2013. He was 85. Karl's career spanned 6 decades and saw geochemistry evolve from a field largely documenting the distributions of chemical elements on Earth to, as he put it, “a tool that…has pervaded the entire field of Earth sciences.” In large part, Karl Turekian was responsible for guiding that evolution.
