I would rather have Charcot's triad because ascending cholangitis is cooler than thrombosis basically. Although a positive Murphy's sign would make me happy, Courvoisier's law would ruin the fun... |

How did these 6 Scientist Robert Hooke-
(1) Hans and Zacharias
Janssen-
(2) Anton van Leeuwenhoek-
(3) Matthias Schleiden-
(4) Theodor Schwann-
(5) Rudolph Virchow.
Robert Hooke Should be number
one on the list. Sorry i
forgot to number him.

Robert hook- Hooke published Micrographia, a book describing his microscopic and telescopic observations, and some original work in biology. Hooke coined the term cell for describing biological organisms, the term being suggested by the resemblance of plant cells to monks' cells Janssen- Both made compound microscope. Leeuwenhock-He is best known for his work on the improvement of the microscope and for his contributions towards the establishment of microbiology. Using his handcrafted microscopes he was the first to observe and describe single celled organisms, which he originally referred to as animalcules, and which we now refer to as microorganisms. He was also the first to record microscopic observations of muscle fibers, bacteria, spermatozoa and blood flow in capillaries (small blood vessels). Schlieden-Matthias Jakob Schleiden (April 5, 1804 - June 23, 1881) was a German botanist and co-founder of the cell theory, along with Theodor Schwann and Rudolf Virchow. Theodor Schwann-Theodor Schwann (December 7, 1810 – January 11, 1882) was a German zoologist. His many contributions to biology include the development of cell theory, the discovery of Schwann cells in the peripheral nervous system, the discovery and study of pepsin, the discovery of the organic nature of yeast, and the invention of the term metabolism. Rudolph Virchow-Rudolf Ludwig Karl Virchow (13 October 1821 – 5 September 1902) was a German doctor, anthropologist, public health activist, pathologist, prehistorian, biologist and politician. He is referred to as the "Father of Pathology," and founded the field of Social Medicine.He gave important sentence in cell theory- OMNIS CELLULAE E CELLULAE. |

who were the three main poeple The two that I know for sure
are Matthias Schleiden and
Theodor Schwann. I am not sure
wether the third one is
virchow or hooke???

Theodor Schwann, Matthias Jakob Schleiden, and Rudolf Virchow. Credit for developing Cell Theory is usually given to two scientists, Theodor Schwann, a zoologist and Matthias Jakob Schleiden, a botanist. In 1839 these two scientists suggested that cells were the basic unit of life. Their theory accepted the first two tenets of modern cell theory. However the cell theory of Schleiden differered from modern cell theory in that it proposed a method of spontaneous crystallization that he called "Free Cell Formation"[4]. In 1858, Rudolf Virchow concluded that all cells come from pre-existing cells thus completing the modern theory. |

Rudolf Ludwig Karl Virchow (born October 13, 1821, in Schivelbein, Pomerania; died September 5, 1902, in Berlin) was a German doctor, anthropologist, public health activist pathologist, prehistorian, biologist and politician. From a farming family of relatively modest means, Virchow studied medicine in Berlin at the military academy of Prussia on a scholarship. When he graduated in 1842 he went to serve as Robert Froriep's assistant at the Berlin Charité rather than the expect military service. He became professor in 1847. Due to political reasons, he moved to Würzburg two years later, where he worked on anatomy. In 1856, he returned to Berlin as a professor of anatomic pathology (a chair created just for him) at Berlin University and the Berlin Charité where he had previously worked as Froriep's assistant. One of major contributions to German medical education was to encourage the use of microscopes by medical students and was known for constantly urging his students to 'think microscopically'. Virchow is credited with multiple significant discoveries. He is cited as the first to recognize leukemia. However, he is perhaps best known for his law Omnis cellula e cellula ("every cell originates from another cell") which he published in 1855. (The epigram was actually coined by François-Vincent Raspail but popularized by Virchow.) This relates to his findings that not the whole organism, but only certain cells or groups of cells can become sick. Virchow is also famous for elucidating the mechanism of pulmonary thromboembolism, thus coining the term embolism. He noted that blood clots in the pulmonary artery originate first from venous thrombi, stating: "The detachment of larger or smaller fragments from the end of the softening thrombus which are carried along by the current of blood and driven into remote vessels. This gives rise to the very frequent process on which I have bestowed the name of Embolia." Related to this research Virchow has been attributed a triad describing the factors contributing to venous thrombosis, Virchow's triad. Virchow founded the medical disciplines of cellular pathology, comparative pathology (comparison of diseases common to humans and animals) and anthropology. His very innovative work may be viewed as sitting between that of Morgagni whose work Virchow studied and that of Paul Ehrlich, who studied at the Charité while Virchow was developing microscopic pathology there. In 1869 he founded the Society for anthropology, ethnology and prehistory (Gesellschaft für Anthropologie, Ethnologie und Urgeschichte) which was very influential in coordinating and intensifying German archaeological research. In 1892 he was awarded the Copley Medal. He was a very prolific writer. Some of his works are: Mittelheilungen über die Typhus-Epidemie, (1848) Die Cellularpathologie, (1858), English translation, (1860) Handbuch der speciellen Pathologie und Therapie, (1854-62) Vorlesungen über Pathologie, (1862-72) Die krankhaften Geschwülste, (1863-67) Gegen den Antisemitismus, (1880) He also developed a standard method of autopsy procedure, named for him, that is still one of the two main techniques used today. Virchow also worked as a politician (member of the Berlin City Council, the Prussian parliament since 1861, German Reichstag 1880-1893) to improve the health care conditions for the Berlin citizens, namely working towards modern water and sewer systems. Virchow is also credited with the founding of "social medicine", frequently focusing on the fact that disease is never purely biological, but often, socially derived. As a co-founder and member of the liberal party (Deutschen Fortschrittspartei) he was an important political antagonist of Bismarck. One area where he co-operated with Bismarck was in the Kulturkampf, the anti-clerical campaign against the Catholic Church claiming that the anti-clerical laws bore "the character of a great struggle in the interest of humanity". It was during the discussion of Falk’s May Laws (Maigesetze) that Virchow first used the term The general ideological enthusiasm among the liberals for the Kulturkampf was in contrast to Bismarck's pragmatic attitude towards the measures and growing disquiet from the Conservatives. Virchow was respected in masonic circles, and according to one source may have been a freemason, though no official record of this has been found. |
