From Research to Practice in Geotechnical Engineering, GSP 180, honors Dr. John H. Schmertmann, Professor Emeritus and P.E., for his contributions to civil engineering. It begins with his biography, a list of his students and writings, followed by reprints of his selection of 16 representative papers from his career. Twenty-eight new, mostly invited papers follow on a great variety of subjects, including: the installation and testing of piles; pile-structure interaction; liquefaction and its mitigation; case histories of settlement and landslide mitigation and capping a superfund landfill; and, computer modeling. The authors include six members of the National Academy of Engineering. This GSP concludes with a paper by one of these, Dr. Schmertmann, which itself concludes with a suggestion for improving your technical writing. Everyone working in the geotechnical profession will find something interesting and useful herein.
