Martin Barry (linguist)
Martin Barry, MD, FRCPE, FRSE, FRS (28 March 1802, Fratton, Portsmouth, Hampshire – 27 April 1855, Beccles, Suffolk), was a British physician who studied histology and embryology. Career He qualified as a doctor in Edinburgh in 1833, and then studied at the University of Heidelberg. He was elected a fellow of the Royal Society in 1840, and had the previous year, in 1839, been awarded the Society's Royal Medal for his work on embryology. He was the first to discover the segmentation of yolk in the mammalian ovum. He enunciated the doctrine that all cells were descended from an original mother cell by cleavage of the nucleus. One of his most fundamental discoveries, published in Philosophical Transactions in 1843, was that spermatozoa could sometimes be found inside the ovum. The note that Barry published was titled ''On the Penetration of Spermatozoa into the Interior of the Ovum''. This work, carried out with rabbits, influenced Theodor Ludwig Wilhelm Bischoff's theories c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal College Of Physicians Of Edinburgh
The Royal College of Physicians of Edinburgh (RCPE) is a medical royal college in Scotland. It is one of three organisations that sets the specialty training standards for physicians in the United Kingdom. It was established by Royal charter in 1681. The college claims to have 12,000 fellows and members worldwide. History The RCPE was formed by a royal charter, granted in 1681, with Sir Robert Sibbald recognised as playing a key part in the negotiations. Three applications preceded this and had been unsuccessful. There were 21 original Fellows, eleven of whom were graduates or students of the University of Leiden. The Universities (Scotland) Act 1858 resulted in several items from the College's Charter becoming obsolete, and they obtained a further charter on 31 October 1861. In 1920 the College enacted changes that allowed women to be admitted on the same terms as men. The charter was amended on 7 May 2005. Edinburgh Pharmacopoeia In 1699 The College first published a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ovum
The egg cell, or ovum (plural ova), is the female reproductive cell, or gamete, in most anisogamous organisms (organisms that reproduce sexually with a larger, female gamete and a smaller, male one). The term is used when the female gamete is not capable of movement (non-motile). If the male gamete (sperm) is capable of movement, the type of sexual reproduction is also classified as oogamous. A nonmotile female gamete formed in the oogonium of some algae, fungi, oomycetes, or bryophytes is an oosphere. When fertilized the oosphere becomes the oospore. When egg and sperm fuse during fertilisation, a diploid cell (the zygote) is formed, which rapidly grows into a new organism. History While the non-mammalian animal egg was obvious, the doctrine ''ex ovo omne vivum'' ("every living nimal comes froman egg"), associated with William Harvey (1578–1657), was a rejection of spontaneous generation and preformationism as well as a bold assumption that mammals also reproduced via ...

Fellows Of The Royal Society Of Edinburgh
The Royal Society of Edinburgh is Scotland's national academy of science and letters. It is a registered charity that operates on a wholly independent and non-partisan basis and provides public benefit throughout Scotland. It was established in 1783. , there are around 1,800 Fellows. The Society covers a broader selection of fields than the Royal Society of London, including literature and history. Fellowship includes people from a wide range of disciplines – science & technology, arts, humanities, medicine, social science, business, and public service. History At the start of the 18th century, Edinburgh's intellectual climate fostered many clubs and societies (see Scottish Enlightenment). Though there were several that treated the arts, sciences and medicine, the most prestigious was the Society for the Improvement of Medical Knowledge, commonly referred to as the Medical Society of Edinburgh, co-founded by the mathematician Colin Maclaurin in 1731. Maclaurin was unhappy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fellows Of The Royal Society
Fellowship of the Royal Society (FRS, ForMemRS and HonFRS) is an award granted by the judges of the Royal Society of London to individuals who have made a "substantial contribution to the improvement of natural knowledge, including mathematics, engineering science, and medical science".

19th-century English Medical Doctors
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the large S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oscar Hertwig
Oscar Hertwig (21 April 1849 in Friedberg – 25 October 1922 in Berlin) was a German embryologist and zoologist known for his research in developmental biology and evolution. Hertwig is credited as the first man to observe sexual reproduction by looking at the cells of sea urchins under the microscope. Biography Hertwig was the elder brother of zoologist-professor Richard Hertwig (1850–1937). The Hertwig brothers were the most eminent scholars of Ernst Haeckel (and Carl Gegenbaur) from the University of Jena. They were independent of Haeckel's philosophical speculations but took his ideas in a positive way to widen their concepts in zoology. Initially, between 1879 and 1883, they performed embryological studies, especially on the theory of the coelom (1881), the fluid-filled body cavity. These problems were based on the phylogenetic theorems of Haeckel, i.e. the biogenic theory (German = biogenetisches Grundgesetz), and the " gastraea theory". Within 10 years, the two bro ...

Fertilisation
Fertilisation or fertilization (see spelling differences), also known as generative fertilisation, syngamy and impregnation, is the fusion of gametes to give rise to a new individual organism or offspring and initiate its development. Processes such as insemination or pollination which happen before the fusion of gametes are also sometimes informally called fertilisation. The cycle of fertilisation and development of new individuals is called sexual reproduction. During double fertilisation in angiosperms the haploid male gamete combines with two haploid polar nuclei to form a triploid primary endosperm nucleus by the process of vegetative fertilisation. History In Antiquity, Aristotle conceived the formation of new individuals through fusion of male and female fluids, with form and function emerging gradually, in a mode called by him as epigenetic. In 1784, Spallanzani established the need of interaction between the female's ovum and male's sperm to form a zygote in frog ...

Theodor Ludwig Wilhelm Bischoff
Theodor Ludwig Wilhelm von Bischoff (28 October 1807 in Hannover – 5 December 1882 in Munich) was a German physician and biologist. Biography He lectured on pathological anatomy at Heidelberg (1835-1843) and held professorships in anatomy and physiology at Giessen (1843-1855) and Munich, where he was appointed to the chair of anatomy and physiology in 1854. In 1843, Theodor von Bischoff was elected as member of the German Academy of Sciences. His most important contributions were made in embryology with a series of four exhaustive memoirs on the development of the mammalian ovum; published in 1842 (rabbit), 1845 (dog), 1852 (guinea pig), and 1854 (roe deer). His studies concerning animal metabolism by measuring urea were less successful, as was his research on the anatomy of skull and brain. He was elected a foreign member of the Royal Netherlands Academy of Arts and Sciences in 1878. Selected works * ''Beiträge zur Lehre von den Eyhüllen des menschlichen Fötus'', 1834 ...
