Dennis Hill is a microbiologist who was employed in medical and industrial microbiology. He has published a variety of papers and is the author of a book addressing basic microbiology for the drinking water industry. He is a member of The American Society for Microbiology, The Iowa Academy of Science, and The American Water Works Association. Dennis' primary objective for creating the Discover a New World Microbe Models was to make it possible for blind students to tactilely study the models in place of viewing microorganisms microscopically. They have filled blind students who have been presented the models for study with enthusiasm. The models also fascinate sighted students and non-microbiologists. Dennis hopes that these models will fulfill his objective of presenting the wonderful world of microbiology to all people. He has always admired Antonie van Leeuwenhoek for his discovery of microorganisms, and he hopes that with his models he plays a small role in enriching van Leeuwenhoek's momentous discovery. The models are globally unique, and only a few sets were cast from models that Dennis made from clay. A few of these sets are used in classrooms to help blind students discover the fascinating world of microbiology.
Herein are photos of the nineteen plates of ninety-four models that represent the major groups of microorganisms. Following the image of each plate are abbreviated explanations of the significance of each microbe.
