Hertwig, Oscar
"Die Zelle und die Gewebe (Vol. 1/2)" by Oscar Hertwig is a scientific publication written in the late 19th century. It presents a foundational synthesis of the general anatomy and physiology of cells and tissues, uniting histology with physiology and developmental biology. Volume one concentrates on the cell’s structure, properties, division, fertilization, and heredity, while the planned second volume addresses tissue structure, origin, and function. The work also situates current knowledge within the history of cell theory and protoplasm, clarifying ongoing scientific debates.The opening of the treatise sets out a clear purpose: to overcome the traditional split between anatomy and physiology at the cellular level and to give cell physiology equal weight alongside structure. In a programmatic preface, Hertwig criticizes standard histology texts for neglecting the living properties of cells, links this book to his university lectures, and frames it as a complement to his embryology text by distinguishing morphological from histological differentiation. He outlines the book’s scope via a detailed table of contents and emphasizes a balanced, historically aware method that presents competing theories without claiming final certainty. The first chapter then surveys the rise of cell theory from plant studies (Malpighi, Grew) through Schleiden’s focus on the nucleus and Schwann’s generalization to animals, noting early errors (membrane-centrism, cytoblastem) and the later shift t…
