Schleiden published Botanik als inductive Wissenschaft , Botany as Inductive Science published in In this monograph Schleiden argues against the philosophy of Frederick Schelling, a philosopher in Germany who published Ideen zu einer Philosophie der Natur als Einleitung in das Studium dieser Wissenschaft Ideas for a Philosophy of Nature: as Introduction to the Study of this Science in He criticized Schelling and Hegel for basing their work solely on ideas rather than on observations and experiments.
In Berlin during the s Rudolf Virchow advocated for the cell theory, for the use of the microscope in pathology, and he refuted some of Schleiden and Schwann's claims about cell formation. Schleiden gave many lectures, often for large audiences, some of which were published, such as 's Die Pflanze und ihr Leben The Plant and Its Life and 's Studien Studies. In he became a full professor of botany at the University of Jena. Schleiden left Jena in to become a professor of anthropology at the University of Dorpat , which later became the University of Tartu when Estonia gained independence from Russia.
After the Russian government granted him a pension, Schleiden became a Privatgelehrter , a private scholar, and frequently moved from city to city. Keywords: cells. Schleiden died on 23 June in Frankfurt am Main, Germany. Sources Amici. Padova: Co' Tipi del Seminario, — Bhatnager, S. The Embryology of Angiosperms, 5th edition.

Schwann was also the first scientist to observe that an egg begins as a single cell and develops into a complex organism by repeated cell division. Matthias Jakob Schleiden was born in Hamburg on April 5, In he entered the University of Heidelburg to study law.
He graduated in , and for a time he practiced law in Hamburg, but then turned to botany and medicine, which he studied at the universities of Gottingen, Berlin, and Jena, finally graduating in After graduating Schleiden was appointed professor of botany at Jena, where he remained until , when he became professor of botany at the University of Dorpat, Estonia.
In he returned to Germany and began teaching privately in Frankfurt-am-Main, where he died on June 23, He was educated at the Jesuit college in Cologne and studied medicine at the universities of Bonn, Wurzburg, and Berlin. He qualified in medicine at Berlin in After graduating he spent four years working as an assistant to the physiologist Johannes Muller —58 at the Museum of Anatomy in Berlin.
We wrote a post on Schwann in Title page of vol. And it has been Schleiden and Schwann ever since. Cell biologists such as Robert Remak, a Polish Jew who did indeed argue, beginning in , that every cell is the result of the division of other cells, and who was quite critical of the erroneous Schleiden-Schwann theory of cell genesis, are hardly mentioned in English textbooks, even today.
Nevertheless, nearly every biology class that visits our history of science collection wants to see Hooke, and Schleiden-Schwann, and we can display all of their works. It would provide their classes with a much more complete picture of the origins of cell theory.
