The development of the microscope involved contributions from multiple inventors prior to the discovery of microorganisms. Notably, eyeglass makers in the Netherlands during the late $${}1500$$s played a foundational role in creating early optical instruments that eventually led to the microscopes used by later scientists.

Microbiology covers the scope and sequence requirements for a single-semester microbiology course for non-majors. The book presents the core concepts of microbiology with a focus on applications for careers in allied health. The pedagogical features of the text make the material interesting and accessible while maintaining the career-application focus and scientific rigor inherent in the subject matter. Microbiology’s art program enhances students’ understanding of concepts through clear and effective illustrations, diagrams, and photographs.

Microbiology is produced through a collaborative publishing agreement between OpenStax and the American Society for Microbiology Press. The book aligns with the curriculum guidelines of the American Society for Microbiology.

Dutch spectacle-makers Hans and Zaccharias Janssen are recognized as early pioneers of microscopy who may have invented the simple microscope, the compound microscope, and the telescope during the late 1500s or early 1600s. They were secretive about their work and left no published records, leaving much about their lives and exact contributions unknown.
