John Crawford (physician)
John Crawford (3 May 1746 – 9 May 1813), an introducer of vaccination into America and investigator into the cause of disease, was born in the north of Ireland May 3, 1746. He was the second of four sons of a Protestant clergyman, all of whom became professional men, his brother Adair being physician to St. Thomas' Hospital, London, and professor of chemistry at Woolwich. At seventeen he entered Trinity College Dublin, and afterwards went to the Leyden University, where he graduated M. D. He then made two voyages to the East Indies as surgeon in the East India Company's service. About 1778 he was married and shortly after received an appointment as surgeon to the Naval Hospital on the Island of Barbadoes, a position of great responsibility. In 1780 a terrible hurricane devastated the island, where upon he furnished aid and medicines to the afflicted inhabitants without stint and without compensation. In 1781 he returned to England on account of bad health and during the voyage ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vaccination
Vaccination is the administration of a vaccine to help the immune system develop immunity from a disease. Vaccines contain a microorganism or virus in a weakened, live or killed state, or proteins or toxins from the organism. In stimulating the body's adaptive immunity, they help prevent sickness from an infectious disease. When a sufficiently large percentage of a population has been vaccinated, herd immunity results. Herd immunity protects those who may be immunocompromised and cannot get a vaccine because even a weakened version would harm them. The effectiveness of vaccination has been widely studied and verified. Vaccination is the most effective method of preventing infectious diseases; widespread immunity due to vaccination is largely responsible for the worldwide eradication of smallpox and the elimination of diseases such as polio and tetanus from much of the world. However, some diseases, such as measles outbreaks in America, have seen rising cases due to relative ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animalcule
Animalcule ('little animal', from Latin ''animal'' + the diminutive suffix ''-culum'') is an old term for microscopic organisms that included bacteria, protozoans, and very small animals. The word was invented by 17th-century Dutch scientist Antonie van Leeuwenhoek to refer to the microorganisms he observed in rainwater. Some better-known types of animalcule include: * '' Actinophrys'', and other heliozoa, termed sun animalcules. * ''Amoeba'', termed ''Proteus'' animalcules. * ''Noctiluca scintillans'', commonly termed the sea sparkles. * ''Paramecium'', termed slipper animalcules. * ''Rotifers'', termed wheel animalcules. * ''Stentor'', termed trumpet animalcules. * ''Vorticella'', and other peritrichs, termed bell animalcules. The concept seems to have been proposed at least as early as about 30 BC, as evidenced by this translation from Marcus Varro's ''Rerum Rusticarum Libri Tres'': Note also if there be any swampy ground, both for the reasons given above, and because certa ...

People From Baltimore
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

18th-century Irish Medical Doctors
The 18th century lasted from January 1, 1701 ( MDCCI) to December 31, 1800 ( MDCCC). During the 18th century, elements of Enlightenment thinking culminated in the American, French, and Haitian Revolutions. During the century, slave trading and human trafficking expanded across the shores of the Atlantic, while declining in Russia, China, and Korea. Revolutions began to challenge the legitimacy of monarchical and aristocratic power structures, including the structures and beliefs that supported slavery. The Industrial Revolution began during mid-century, leading to radical changes in human society and the environment. Western historians have occasionally defined the 18th century otherwise for the purposes of their work. For example, the "short" 18th century may be defined as 1715–1789, denoting the period of time between the death of Louis XIV of France and the start of the French Revolution, with an emphasis on directly interconnected events.

Mosquito-malaria Theory
Mosquito-malaria theory (or sometimes mosquito theory) was a scientific theory developed in the latter half of the 19th century that solved the question of how malaria was transmitted. The theory proposed that malaria was transmitted by mosquitoes, in opposition to the centuries-old medical dogma that malaria was due to bad air, or miasma. The first scientific idea was postulated in 1851 by Charles E. Johnson, who argued that miasma had no direct relationship with malaria. Although Johnson's hypothesis was forgotten, the arrival and validation of the germ theory of diseases in the late 19th century began to shed new lights. When Charles Louis Alphonse Laveran discovered that malaria was caused by a protozoan parasite in 1880, the miasma theory began to subside. An important discovery was made by Patrick Manson in 1877 that mosquito could transmit human filarial parasite. Inferring from such novel discovery, Albert Freeman Africanus King proposed the hypothesis that mosquitoes w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Malaria
The history of malaria extendes from its prehistoric origin as a zoonotic disease in the primates of Africa through to the 21st century. A widespread and potentially lethal human infectious disease, at its peak malaria infested every continent except Antarctica. Its prevention and treatment have been targeted in science and medicine for hundreds of years. Since the discovery of the ''Plasmodium'' parasites which cause it, research attention has focused on their biology as well as that of the mosquitoes which transmit the parasites. References to its unique, periodic fevers are found throughout recorded history, beginning in the first millennium BC in Greece and China. For thousands of years, traditional herbal remedies have been used to treat malaria. The first effective treatment for malaria came from the bark of the cinchona tree, which contains quinine. After the link to mosquitos and their parasites was identified in the early twentieth century, mosquito control measures su ...

Freemason
Freemasonry or Masonry refers to fraternal organisations that trace their origins to the local guilds of stonemasons that, from the end of the 13th century, regulated the qualifications of stonemasons and their interaction with authorities and clients. Modern Freemasonry broadly consists of two main recognition groups: * Regular Freemasonry insists that a volume of scripture be open in a working lodge, that every member profess belief in a Supreme Being, that no women be admitted, and that the discussion of religion and politics be banned. * Continental Freemasonry consists of the jurisdictions that have removed some, or all, of these restrictions. The basic, local organisational unit of Freemasonry is the Lodge. These private Lodges are usually supervised at the regional level (usually coterminous with a state, province, or national border) by a Grand Lodge or Grand Orient. There is no international, worldwide Grand Lodge that supervises all of Freemasonry; each Grand Lod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
