Branches of Cell Biology

Matthias Schleiden, Theodor Schwann, and Rudolf Virchow

The Scientists - Num. 1

Matthias Schleiden

Personal Biography - Born April 5th, 1804 and died June 23rd, 1881. He was educated at Heidelberg, practiced law in Hamburg, and ended up study plant cells under a microscope. He became a professor of botany in Dorpat, Russia in 1863.

Scientific Biography - Considered a founding father of biology. He stressed that structures and morphological features, not processes, gives organic life its character. He also found that a nucleated cell is the first element of the plant embryo.

Biology Legacy - Biology is the study of life, and studying cells is a great part of it. He looked deep into plants especially and gave us the information we now know about them in textbooks.

The Scientists - Num. 2

Theodor Schwann

Personal Biography - Born on December 7th, 1810, Neuss, Germany, and died January 11th, 1882. He began his medical studies at the University of Wuerzburg. In 1836, he isolated a substance responsible for digestion in animals and named it pepsin. He was also one of the first scientists to contribute to the germ theory of alcoholic fermentation. After this is when he switched to studying the cells in animals.

Scientific Biography - He played a vital role in the development of the cell theory and defined the cell as the fundamental unit of animal structure. He also created the term ¨metabolism.¨ He implemented his cell theory from Schleiden into animals and concluded that every tissue in an animal has an embryonic cell.

Biology Legacy - He helped create the term metabolism which we use a lot today just talking and while talking about science. He also helped look inside to what animal tissue is made up of, cells.

The Scientists - Num. 3

Rudolf Virchow

Personal Biography - 19th century German pathologist and politician who was known for his important findings in social medicine. He is also the founding father of physics. He developed pathological processes. He drew influences from cell theories, and analyzed effects of diseases in different organs and tissues in the human body.

Scientific Biography - He launched the field of cellular pathology. He stated that diseases involve changes in normal cells. This also meant that diseases could be defined more sharply. He made discoveries such as finding cells in bone, and connective tissue. He was also the first person to recognize leukemia. He found a link from animal to human diseases

Biology Legacy - His findings led major progresses in medicine. This allowed doctors to treat patients more quickly using the right antibiotics and could identify the diseases they had more soon.
