Scientist of the Day - Matthias Schleiden
Matthias Jakob Schleiden, a German botanist and microscopist, was born Apr. 5, Most people vaguely remember "Schleiden and Schwann" from their high-school biology course, where one briefly encountered them right after learning that Robert Hooke coined the word “cell” (you might have been taught that Hooke discovered the cell, but that is not quite the same thing). As to Schleiden and Swann, you probably learned that Schleiden, the botanist, and Theodor Swann, the animal anatomist, discovered that the cell is the fundamental unit of all living things. As is often the case, the truth is not quite so simple. Schleiden did publish a paper in , called "Beiträge zur Phytogenesis" (“Contributions to studies on the origin of plants”). It appeared in a journal with the formal title, Archiv für Anatomie, Physiologie und wissenschaftliche Medizin, which is often referred to as Müller's Archiv, after the editor, Johannes Müller, who just happened to be Schleiden's teacher in Berlin.

Schleiden and Schwann - the first masons of the cellular theory
Russian physiologist Ivan Pavlov has a comparison of science with construction, where knowledge, like bricks, creates the foundation of the system. So the cell theory with its founders - Schleiden and Schwann - is shared by many naturalists and scientists, their followers. One of the creators of the theory of the cellular structure of organisms R. Virchow once said: "Schwann stood on the shoulders of Schleiden." It is about the joint work of these two scientists that will be discussed in the article. On the cellular theory of Schleiden and Schwann.

Matthias Jakob Schleiden
German Botanist
Matthias Jakob Schleiden and Theodor Schwann () are generally regarded as the first scientists to establish cell theory. Cell theory is a fundamental aspect of modern biology. This powerful generalization has played an essential role in explaining the basic unity of plant and animal life, the mechanism of inheritance, fertilization, development and differentiation, and evolutionary theory. Building upon the discovery of the cell nucleus by Robert Brown (), Schleiden demonstrated that plants are composed of cells and cell products.
Schleiden studied law at the University of Heidelberg, but he was so unsuccessful in his attempts to establish a law practice in Hamburg that he was driven to suicide. Fortunately, his self-inflicted gunshot wound was not fatal. By the time he had recovered from his injury and depression, Schleiden decided to give up law and study natural science. He earned doctorates in medicine and philosophy and was appointed professor of botany at the University of Jena. Despite his success in research and teaching, he suffered from nervousness, fatigue, and depression. He resigned after 12 years and decided to r
