Richard Friedrich Johannes Pfeiffer
Richard Friedrich Johannes Pfeiffer FRS (27 March 1858 – 15 September 1945) was a German physician and bacteriologist. Pfeiffer was born to Otto Pfeiffer, a German pastor of the local Evangelical parish, and Natalia née Jüttner, in Treustädt, Province of Posen (Prussia), and died in Bad Landeck (Prussia, now Poland). Career Pfeiffer is remembered for his many fundamental discoveries in immunology and bacteriology, particularly for the phenomenon of bacteriolysis. In 1894 he found that live cholera bacteria could be injected without ill effects into guinea pigs previously immunised against cholera, and that blood plasma from these animals added to live cholera bacteria caused them to become motionless and to lyse. This could be inhibited by previously heating the blood plasma. He called this bacteriolysis and it became known as the Pfeiffer Phenomenon, or Isayev-Pfeiffer phenomenon. Working with Robert Koch in Berlin he intellectually and experimentally conceived t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oekology
Home economics, also called domestic science or family and consumer sciences (often shortened to FCS or FACS), is a subject concerning human development, personal and family finances, consumer issues, housing and interior design, nutrition and food preparation, as well as textiles and apparel. Although historically mostly taught in secondary school or high school, dedicated home economics courses are much less common today. Home economics courses are offered around the world and across multiple educational levels. Historically, the purpose of these courses was to professionalize housework, to provide intellectual fulfillment for women, to emphasize the value of "women's work" in society, and to prepare them for the traditional roles of sexes. Family and consumer sciences are taught as an elective or required course in secondary education, as a continuing education course in institutions, and at the primary level. Beginning in Scotland in the 1850s, it was a woman-dominated c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ellen Swallow Richards
Ellen Henrietta Swallow Richards ( Swallow; December 3, 1842 – March 30, 1911) was an American industrial and safety engineer, environmental chemist, and university faculty member in the United States during the 19th century. Her pioneering work in sanitary engineering, and experimental research in domestic science, laid a foundation for the new science of home economics. She was the founder of the home economics movement characterized by the application of science to the home, and the first to apply chemistry to the study of nutrition. Richards graduated from Westford Academy (second oldest secondary school in Massachusetts) in 1862. She was the first woman admitted to the Massachusetts Institute of Technology. She graduated in 1873 and later became its first female instructor. Richards was the first woman in America accepted to any school of science and technology, and the first American woman to obtain a degree in chemistry, which she earned from Vassar College in 1870 ...

Naturalist
Natural history is a domain of inquiry involving organisms, including animals, fungi, and plants, in their natural environment, leaning more towards observational than experimental methods of study. A person who studies natural history is called a naturalist or natural historian. Natural history encompasses scientific research but is not limited to it. It involves the systematic study of any category of natural objects or organisms, so while it dates from studies in the ancient Greco-Roman world and the mediaeval Arabic world, through to European Renaissance naturalists working in near isolation, today's natural history is a cross-discipline umbrella of many specialty sciences; e.g., geobiology has a strong multidisciplinary nature. Definitions Before 1900 The meaning of the English term "natural history" (a calque of the Latin ''historia naturalis'') has narrowed progressively with time, while, by contrast, the meaning of the related term "nature" has widened (see also ...

Scottish American
Scottish Americans or Scots Americans (; ) are Americans whose ancestry originates wholly or partly in Scotland. Scottish Americans are closely related to Scotch-Irish Americans, descendants of Ulster Scots, and communities emphasize and celebrate a common heritage.Celeste Ray, 'Introduction', p. 6, id., 'Scottish Immigration and Ethnic Organization in the United States', pp. 48-9, 62, 81, in id. (ed.), ''The Transatlantic Scots'' (Tuscaloosa, AL:University of Alabama Press, 2005). The majority of Scotch-Irish Americans originally came from Lowland Scotland and Northern England before migrating to the province of Ulster in Ireland (see ''Plantation of Ulster'') and thence, beginning about five generations later, to North America in large numbers during the eighteenth century. The number of Scottish Americans is believed to be around 25 million, and celebrations of Scottish identity can be seen through Tartan Day parades, Burns Night celebrations, and Tartan Kirking cere ...
