Mar 2, 2018 · This idea stimulated the concept of German philosopher Lorenz Oken (1779–1851) that all organisms are composed of “infusoria” and “Urbläschen” (primordial bubbles) as basic life units; this speculation directly preceded the works of the first empirical cell biologists (Canguilhem 2008; Harris 2000). However, it was only the invention ...

Johannes Peter Müller, who has become one of the most distinguished physiologists of Germany, was born in Koblenz into a shoemaker’s family on July 14, 1801. Educated in the faith of the Catholic Church, he entered a Latin seminary of the Jesuits. At first, Müller wanted to start a life path as a Roman Catholic priest. Nevertheless, he got interest...
Schwann was born in Neuss on the Rhine, a few miles from Cologne. He received an excellent training in mathematics and physics at the Jesuits College and started to study medicine in 1829. Schwann received his MD in 1834 in Berlin and learned anatomy, physiology, and general pathology from Johannes Müller (1801–1858). During these years spent under...
Rokitansky (Fig. 2) was one of the towering figures in the history of pathological anatomy. Karl Freiherr von Rokitansky was born on February 19, 1804, in Königgrätz (today Hradec Králové, Bohemia, Czech Republic) and died on July, 23, 1878, in Vienna, Austria. He studied in Prague and Vienna and started his career in the morgue of the Allgemeine K...

Was war Lorenz Oken?
His general ideas about the elemental structures of living organisms, though specifically incorrect, anticipated the subsequent identification of the cell and development of cell theory. He was also a founder of scientific congresses or meetings.
Lorenz Okenfuss (Oken) (1779–1851) claimed that living beings were a synthesis of infusorians. All these proposals have in common the fact that they are conceptions about the possibility of a microscopic and universal structure.

May 29, 2018 · Oken did hundreds of experiments with chick embryos to gather information on cell theory with Karl Ernst von Baer (1792–l876), comparative embryologist and proponent of epigenetic thinking. Oken pronounced the seminal insight: “ontogeny recapitulates phylogeny.”
His prolific speculations, however, foreshadowed cell theory, as in the idea that all tissues were composed of a "fundamental polyp," or "infusorian." He described the force of attraction between the Sun and Earth, as well as light, as tension in ether.
The paper focuses on the work of Lorenz Oken (1779–1851) in an attempt to make sense of the role played by Romantic Naturphilosophie in the development of natural history in Germany at the turn of the nineteenth century. It first focuses on the role played by Schelling and his Würzburg circle in the development of Oken's early views on ...
