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.
Matthias Jakob Schleiden (1804–1881) Theodor Schwann (1810–1882) Credit for developing cell theory is usually given to two scientists: Theodor Schwann and Matthias Jakob Schleiden. [9] While Rudolf Virchow contributed to the theory, he is not as credited for his attributions toward it. In 1839, Schleiden suggested that every structural part ...

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. [93] By 1850, an invigorated organic chemistry had revealed the structure of many plant constituents. [94]
