From simple suggestions sometimes spring great accomplishments. For Wolfgang Berger the beginning was a suggestion from his doctoral advisor, Fred Phleger, who said, in response to a question about what Wolf might pursue for a dissertation, “study planktonic foraminifera.”

At the time the suggestion probably would not have been of interest to a geophysics or geochemistry student, but luckily for all of us, Wolfs early training was in paleontology and stratigraphy, and he took Fred's suggestion. The result has been a rich flow of ideas about the formation and preservation of biogenic sediments in the deep-sea carbonate dissolution, climatic change, global ocean productivity, and the Cenozoic ocean.
