Matthias Jakob Schleiden (German: [maˈtiːas ˈjaːkɔp ˈʃlaɪdn̩]; [1] [2] 5 April 1804 – 23 June 1881) was a German botanist and co-founder of cell theory, along with Theodor Schwann and Rudolf Virchow.
The cell was first discovered by Robert Hooke in 1665 using a microscope. The first cell theory is credited to the work of Theodor Schwann and Matthias Jakob Schleiden in the 1830s. In this theory the internal contents of cells were called protoplasm and described as a jelly-like substance, sometimes called living jelly.
The book, originally published in German, was translated to English in 1847 by Henry Spencer Smith in an edition that also contained the treatise Phytogenesis, by Matthias Schleiden. [ 4 ] Besides the theoretical work, that Schwann called a "philosophical" section of general anatomy , [ 4 ] Schwann provided several plates with drawings of cells ...
In 1837, Matthias Jakob Schleiden viewed and stated that new plant cells formed from the nuclei of old plant cells. Dining with Schwann one day, their conversation turned on the nuclei of plant and animal cells.
Even so, botany was greatly stimulated by the appearance of the first "modern" textbook, Matthias Schleiden's (1804–1881) Grundzüge der Wissenschaftlichen Botanik, published in English in 1849 as Principles of Scientific Botany. [94] By 1850, an invigorated organic chemistry had revealed the structure of many plant constituents. [95]
From the perspective of the history of science, the cell theory founded by Matthias Jacob Schleiden proved to be particularly influential. In his 1838 publication on phytogenesis, Schleiden declared the cell as the fundamental unit of all plants and identified the cell nucleus, which was discovered in 1831, as an essential factor in plant ...

This was ultimately concluded by plant scientist Matthias Schleiden [5] and animal scientist Theodor Schwann in 1838, who viewed live cells in plant and animal tissue, respectively. [3] 19 years later, Rudolf Virchow further contributed to the cell theory, adding that all cells come from the division of pre-existing cells. [3]
