Alfred Hershey
Alfred Day Hershey (December 4, 1908 – May 22, 1997) was an American Nobel Prize–winning bacteriologist and geneticist. Early years Hershey was born in Owosso, Michigan to Robert Day and Alma Wilbur Hershey. He earned a B.S. in chemistry in 1930, and Ph.D. in bacteriology in 1934 from Michigan State University. Shortly after, Hershey accepted a faculty position at Washington University in St. Louis, serving as an instructor of bacteriology and immunology from 1934 to 1950. Bacteriophage research At Washington University, Hershey worked closely with department head Jacques Bronfenbrenner to investigate bacteriophages, or phages—viruses that infect and replicate inside bacteria. Hershey's work on the factors impacting the virus' ability to infect its targets brought him to the attention of fellow phage researchers Max Delbrück and Salvador Luria. The Phage Group In 1943, Delbrück invited Hershey to Vanderbilt University to discuss his phage research. Together, w ...

Owosso, Michigan
Owosso () is the largest city in Shiawassee County in the U.S. state of Michigan. The population was 14,714 at the 2020 census. It is located west of Flint, and northeast of Lansing.

Papal Infallibility
Papal infallibility is a Dogma in the Catholic Church, dogma of the Catholic Church which states that, in virtue of the promise of Jesus to Saint Peter, Peter, the Pope when he speaks is preserved from the possibility of error on doctrine "initially given to the Apostolic Age, apostolic Church and handed down in Catholic Bible, Scripture and Sacred Tradition, tradition". It does not mean that the pope cannot Christian views on sin, sin or otherwise err in some capacity, though he is prevented by the assistance of the Holy Spirit from issuing heretical teaching even in his non-infallible Magisterium, as a corollary of indefectibility. This doctrine, defined dogmatically at the First Vatican Council of 1869–1870 in the document , is claimed to have existed in medieval theology and to have been the majority opinion at the time of the Counter-Reformation. The doctrine of infallibility relies on one of the cornerstones of Catholic dogma, that of papal supremacy, whereby the autho ...

Franklin Stahl
Franklin (Frank) William Stahl (born October 8, 1929) is an American molecular biologist and geneticist. With Matthew Meselson, Stahl conducted the famous Meselson-Stahl experiment showing that DNA is replicated by a semiconservative mechanism, meaning that each strand of the DNA serves as a template for production of a new strand. He is Emeritus Professor of Biology at the University of Oregon's Institute of Molecular Biology in Eugene, Oregon. Career Stahl, like his two older sisters, graduated from the public schools of Needham, a Boston suburb. In 1951, he was awarded an AB degree in biology from Harvard College, and matriculated in the biology department of the University of Rochester. His interest in genetics was cemented in 1952 by his introduction to bacterial viruses (phages) in a course taught by A. H. (Gus) Doermann at the Cold Spring Harbor Biological Laboratory. In 1956, he received a PhD in biology for his work with Doermann on the genetics of T4 phage. In 195 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
