About the author
Walter D. Keller was an American geologist, clay mineralogist, and sedimentologist who lived from March 13, 1900, to March 23, 2001. Reliable sources describe him as an internationally recognized scholar in clay minerals and sedimentary geology, and he earned both his A.B. and M.A. degrees in geology from the University of Missouri.
He spent much of his career at the University of Missouri, where he was also remembered as a gifted teacher. Alongside his scientific papers, he wrote books for broader audiences, including The Common Rocks and Minerals of Missouri and The Principles of Chemical Weathering, reflecting a talent for explaining earth science in a direct, useful way.
Keller’s long life and career left a strong mark on geology education and research. Professional organizations honored him with major awards, and memorial notices after his death emphasized both his scholarship and his influence on generations of students and fellow geologists.
