Robert Remak ($${}1815$$–$${}1865$$) was a prominent neurologist and embryologist who published convincing evidence in $${}1852$$ that cells are derived from other cells as a result of cell division. This idea, which forms the basis of the principle of biogenesis, was initially questioned by many in the scientific community before gaining wider acceptance.

Rudolf Virchow ($${}1821$$–$${}1902$$) was a Polish-born German scientist known as the 'Father of Pathology.' He pioneered determining the causes of diseases by examining their effects on tissues and organs, and was among the first to use animals in his research. Virchow popularized the second tenet of modern cell theory in his $${}1855$$ editorial essay 'Cellular Pathology,' using the Latin phrase omnis cellula a cellula ('all cells arise from cells').

There is historical controversy regarding who should receive credit for articulating the central tenet of modern cell theory, the principle of biogenesis. Although Rudolf Virchow popularized the idea that all cells arise from other cells in his $${}1855$$ essay 'Cellular Pathology,' his former colleague Robert Remak had published the same idea $${}3$$ years earlier. In $${}1858$$, Virchow dismissively claimed that his $${}1855$$ publication was an editorial rather than a scientific paper, and thus did not require a citation for Remak's prior work.

Controversy over the Principle of Biogenesis

The principle of biogenesis is a basic tenet of modern cell theory which states that all cells only come from other cells.

Developed in the 17th century following early observations of microscopic life, the cell theory is a foundational scientific principle. It posits three main claims: the cell is the fundamental unit of life, all living organisms contain at least one cell, and new cells can only arise from pre-existing cells.

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.

Principle of Biogenesis

Although cells were first observed by Robert Hooke in the 1660s, cell theory was not widely accepted in the scientific community for approximately 200 years. The subsequent work and observations of scientists like Matthias Schleiden, Theodor Schwann, Robert Remak, and Rudolf Virchow were critical in establishing its general acceptance.
