Here is a copy of what the scientist, Nobu Shimizu, presented to me. Sketched here is a history of the development of Geochemistry. The major publications are listed by author, visually expanding the knowledge of particular isotopes. Major events relevant to geochemistry are also presented, with special reference to Claude Allegre, former Minister of Science of France, who was instrumental in the development of this field of science.




Here is where I got to have fun: I chose to illustrate this history in the context of an "olde mappe." This slide was presented by Nobu Shimizu, also an accomplished geochemist, at the Allegre Symposium (in Allegre's honor for his 60th birthday in 1997), as the keynote address for the conference. It was so popular, that we got several dozen requests for reprints of the image as a small poster!
