Cell Biology

The study of cells in which you learn the structure, formation, components, and functions. It revolves around the concept that the cell is the fundamental unit of life. Some examples of a cell are trees, worms, bacteria and protozoa. Some would be classified as a single cell or multi cell. Scientist would use microscopes to be able to see the cells.

Mattais Schleiden

Matthias was born on April 5, 1804 in Hamburg, Germany. HIs first profession that he studied for was a lawyer in Heidelberg University. Even though he was successful, he wasn't satisfied with it. He tried to kill himself but was rescued and decided to change his life. So, he studied medicine and botany at Jena University. He was appointed as Associate and Honorary professor as well as vice president and dean at University of Jena and Dorpat. He died on June 23, 1881.

Matthias profession lead him to have his doctor in 1839 in Jena University. He wrote many scientific writing that became famous and were published in high respected magazines. In 1842 he was the author of "Broad Scientific Botany". In 1862 he leaves Jena and went to Dorpat for a short time. Matthias published writing about phytogenesis in Mueller's archive of anatomy, physiology, and scientific medicine.

Schleiden was a respected botanist who was the founder of the cell theory which stated that different parts of plants were made up of cells in 1838. He also published a structure of the plant cell and the importance of the nucleus. Matthias was one of the first German Biologist who accepted the theory of evolution by Darwin.

Theodor Schwann

Theodor Schwann was born on December 7, 1810 in Neuss Germany. As a boy he spent a large sum of time in building machines of all kind. Theodor's profession was in the medical studies. He first college was Jesuits then Bonn. He later went to Wurzburg then later graduated at Berlin in 1834. He was then persuaded by Muller to enter the scientific field. He worked as an appointed assistant at the anatomical museum. He was described as a gentle and amiable character. He died on January 11, 1882 in Cologne Germany.

Schwann collaborated with Muller time to time. He assisted him with the experimental work Mullers great physiology book. During that time was when he made his most valuable work. Theodor worked for a physico-chemical explanation of life. In his experiment for spontaneous generation he was convinced that it was false. In that time he also found that yeast originally came of fermentation in 1836. He also studied muscles in the esophagus and nerve fibers.

Theodor Schwann was a physiologist who made the discovery of the digestive enzyme pepsin. He also researched fermentation of grain and muscle movements. He continued the study of the cell theory of animals. He proved that every animal tissue is made of embryonic cells. He made many historical achievements.

Rudolf Virchow

Rudolf Virchow was born on October 13, 1871 in Swidwin Poland. His parents were a farmer and a city treasurer and he was an only child. His interest was in natural science. In 1839 he received a scholarship from the Prussian Military Academy. He was given the chance to study medicine for a career as an army physician. Rudolph studied medicine in Berlin and then taught it for many years. He died on September 5, 1902 in Berlin Germany.

Rudolf graduated as a doctor in 1843. He studied pathological histology at Charite Hospital. He wrote a paper that described two earlier cases of leukemia. He and Benno Reinhardt started a new journal called "Archives for Pathological Anatomy and Physiology, and for Clinical Medicine". In 1848 Virchow was selected to investigate the outbreak of typhus. He put the blame on the government and social conditions. In return the government had to deal with the revolution of Berlin in 1848. He decided to to embrace the many abolitions. In 1856 the University of Berlin established pathological anatomy chair for him. He was appointed Berlin city council and focused on public health.

One of the greatest achievements of Virchow was that his observation stated that a whole organism does not get sick - only certain cells or groups. He started the field of cellular pathology which he stated that all disease involve changes in normal cells. In which caused great advancement such as doctors would be able to an accurate diagnosis. He found cells in bones and was the first person to explain the works of pulmonary thromboembolism.
