EXCERPTS FROM SOLIDS HANDLING AWARD LETTERS

"There's no doubt that you have made an outstanding contribution to the science and technology of bulk solids handling. The tremendous advances in research and industrial applications of the field of solids handling over the past 30 or more years are due to you directly as well as to the stimulation you have provided to researchers in various countries of the world. For me personally your research has been instrumental in my professional interest and activity in solids handling in Australia."
- Prof. Alan W. Roberts, Director, Institute for Bulk Materials Handling Research, The University of Newcastle, Australia

"The fact that many researchers have followed in your footsteps but still have yet to bring about any significant improvements in the procedures established by yourself is a measure of your contribution to the field. Also the establishment of Jenike & Johanson, Inc. with a view to making available the technology to the solids handling community at large should not be overlooked. The fact that this company has now blossomed into one of the premier consulting organizations in the world in this area is a further testament to the contribution of your pioneering work."
- Prof. Alan R. Reed, Director, The Wolfson Centre for Bulk Solids Handling Technology, England

"For industry a tremendous step forward has been achieved by your work. The fact that you not only theoretically analyzed the mechanics of powder flow but also have developed with your shear cell an experimental device for determining all relevant properties for silo design in combination with a relatively easy design procedure has helped engineers throughout the world to solve their problems in solids handling. In addition structural questions as well were addressed by your research work."
- Dr. Ing. Harald Wilms, Zeppelin

"The standards you've set, both in creative output and written examination, leave no doubt that you are the preeminent voice in bulk solids flow theory and application. Your contribution to my own education were and continue to be invaluable." - Jerry R. Johanson, Ph.D.

"We all owe you a great debt for envisioning, creating and becoming the driving force for research and development of the bulk solids handling technology that is now being applied all over the world."
- Fred Thomson, DuPont (retired)

"Andrew Jenike was the pioneer of bulk solids flow research leading to a proper understanding of storage equipment behavior. His work has saved the industry millions in avoiding loss production and downtime either by the correct initial design of storage systems or the necessary modification of malfunctioning existing installations. On the academic front his work advanced the science of powder flow into a new era and still after so many years forms the design basis of bins, hoppers and silos."
- A.S. Goldberg, Director, Powder Advisory Centre, Israel

"Your determination and single mindedness in working each day on applying plasticity theory to soil mechanics made a very big impression on me. It was your quickness in seeing the possibilities of theory that led us to start writing the paper on the flow of solids beyond Coulomb failure within about three weeks. You supplied the ideas and I helped with the details."
- Richard T. Shield, Professor, University of Illinois (retired)

"Nobody has influenced my scientific and professional career the way you did. I am still working in bulk solids technology as my main research topic, have already 28 years of experience both in research and application, and the bases of this work are Jenike's radial stress field, Jenike's effective yield locus, and Jenike's method to design silos for mass flow and for reliable flow without flow obstructions."
- Prof. Dr. Ing. Jorg Schwedes, Braunschweig University, Germany
