John Thomas Patterson (geneticist)
John Thomas Patterson (November 3, 1878 – December 4, 1960) was an American geneticist and professor at the University of Texas. Early life Patterson was born from James and Anna Patterson in a family of 5 children on a farm near Piqua, Ohio on November 3, 1878. As a child he attended a nearby county school, completing 9 grades before contracting pneumonia. He returned to his studies in his late teens at a school in Ada, Ohio. in 1900 he began his studies as a B.A. undergraduate at the College of Wooster. He had aspired to study medicine and as such enrolled at the University of Chicago to better prepare himself. But there he was only allowed to study zoology as they were the only courses available in the summer quarter. He was persuaded to stay on as a researcher and subsequently completed his Ph.D. in June 1908. While teaching at Buena Vista College he met his future spouse Alice Jane Tozier, a teacher in English and Latin, with whom he bought a house in Woods Hole, Massa ...

Piqua, Ohio
Piqua ( ) is a city in Miami County, southwest Ohio, United States, 27 miles north of Dayton. The population was 20,522 at the 2010 census. It is part of the Dayton Metropolitan Statistical Area. It was founded as the village of Washington in 1807 by a soldier under Gen. Anthony Wayne. History Etymology The word 'Piqua' is believed to be derived from a Shawnee language phrase: ''Othath-He-Waugh-Pe-Qua,'' translated as "He has risen from the ashes," related to a legend of the people. It became associated with the ''Pekowi'', one of the five divisions of the Shawnee people, who were eventually known as the Piqua. Fort and trading post In 1749, Fort Pickawillany was constructed by the British to protect their trading post at a Miami village of the same name. It was located at the confluence of Loramie Creek and the Great Miami River. (The present city of Piqua developed about a mile to the southwest). In 1752 Charles de Langlade, an Odawa war chief of partial French Canadia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
X-ray
An X-ray, or, much less commonly, X-radiation, is a penetrating form of high-energy electromagnetic radiation. Most X-rays have a wavelength ranging from 10 picometers to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz ( to ) and energies in the range 145 eV to 124 keV. X-ray wavelengths are shorter than those of UV rays and typically longer than those of gamma rays. In many languages, X-radiation is referred to as Röntgen radiation, after the German scientist Wilhelm Conrad Röntgen, who discovered it on November 8, 1895. He named it ''X-radiation'' to signify an unknown type of radiation.Novelline, Robert (1997). ''Squire's Fundamentals of Radiology''. Harvard University Press. 5th edition. . Spellings of ''X-ray(s)'' in English include the variants ''x-ray(s)'', ''xray(s)'', and ''X ray(s)''. The most familiar use of X-rays is checking for fractures (broken bones), but X-rays are also used in other ways. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1960 Deaths
Year 196 ( CXCVI) was a leap year starting on Thursday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Dexter and Messalla (or, less frequently, year 949 ''Ab urbe condita''). The denomination 196 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Geographic Isolation
Allopatric speciation () – also referred to as geographic speciation, vicariant speciation, or its earlier name the dumbbell model – is a mode of speciation that occurs when biological populations become geographically isolated from each other to an extent that prevents or interferes with gene flow. Various geographic changes can arise such as the movement of continents, and the formation of mountains, islands, bodies of water, or glaciers. Human activity such as agriculture or developments can also change the distribution of species populations. These factors can substantially alter a region's geography, resulting in the separation of a species population into isolated subpopulations. The vicariant populations then undergo genetic changes as they become subjected to different selective pressures, experience genetic drift, and accumulate different mutations in the separated populations' gene pools. The barriers prevent the exchange of genetic information between ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wilson Stuart Stone (October 6, 1907 – February 28, 1968) was an American geneticist and zoologist. Stone received his bachelor, Masters and PhD at the University of Texas and joined the department of zoology in 1932. Stone mentors were J. T. Patterson, H.J. Muller, and Theophilus Painter.

National Academy Of Sciences
The National Academy of Sciences (NAS) is a United States nonprofit, non-governmental organization. NAS is part of the National Academies of Sciences, Engineering, and Medicine, along with the National Academy of Engineering (NAE) and the National Academy of Medicine (NAM). As a national academy, new members of the organization are elected annually by current members, based on their distinguished and continuing achievements in original research. Election to the National Academy is one of the highest honors in the scientific field. Members of the National Academy of Sciences serve '' pro bono'' as "advisers to the nation" on science, engineering, and medicine. The group holds a congressional charter under Title 36 of the United States Code. Founded in 1863 as a result of an Act of Congress that was approved by Abraham Lincoln, the NAS is charged with "providing independent, objective advice to the nation on matters related to science and technology. ... to provide scien ...

American Society Of Zoologists
The Society for Integrative and Comparative Biology is organized to integrate the many fields of specialization which occur in the broad field of biology.. The society was formed in 1902 as the American Society of Zoologists, through the merger of two societies, the "Central Naturalists" and the "American Morphological Society" (founded in 1890). The Ecological Society of America split from it in 1915, and another society of geneticists also split from it in 1930. In 1996 the name was changed to the Society for Integrative and Comparative Biology. The society publishes two scientific journals: the bimonthly journal ''Integrative and Comparative Biology (''formerly the ''American Zoologist'') and ''Evolution & Development ''Evolution & Development'' is a peer-reviewed scientific journal publishing material at the interface of evolutionary and developmental biology. Within evolutionary developmental biology, it has the aim of aiding a broader synthesis of biologi ...''.. It is or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hermann Joseph Muller
Hermann Joseph Muller (December 21, 1890 – April 5, 1967) was an American geneticist, educator, and Nobel laureate best known for his work on the physiological and genetic effects of radiation (mutagenesis), as well as his outspoken political beliefs. Muller frequently warned of long-term dangers of radioactive fallout from nuclear war and nuclear testing, which resulted in greater public scrutiny of these practices. Early life Muller was born in New York City, the son of Frances (Lyons) and Hermann Joseph Muller Sr., an artisan who worked with metals. Muller was a third-generation American whose father's ancestors were originally Catholic and came to the United States from Koblenz. His mother's family was of mixed Jewish (descended from Spanish and Portuguese Jews) and Anglican background, and had come from Britain. Among his first cousins are Herbert J. Muller and Alfred Kroeber (Kroeber is Ursula Le Guin's father). As an adolescent, Muller attended a Unitarianism, Unitarian ...
