Herman Branson
Herman Russell Branson (August 14, 1914 – June 7, 1995) was an American physicist, chemist, best known for his research on the alpha helix protein structure, and was also the president of two colleges. He received a fellowship from the Rosenwald Foundation. Early life Branson received his B.S. from Virginia State College in 1936, and his Ph.D. in physics from the University of Cincinnati, under the direction of Boris Podolsky, in 1939. His thesis was in three parts, the first involved the interaction of x-rays with Tubifex tubifex (or sludge worm), the second involving the design and construction of an X-ray intensity measuring device, and the third section on the quantization of mass using the Dirac Equation. After a stint at Dillard University, he joined Howard University in 1941 as an assistant professor of physics and chemistry. As a scientist, Branson made significant contributions to how proteins work, and how they contribute to diseases such as sickle cell anemia. ...

Morgan State University
Morgan State University (Morgan State or MSU) is a public historically black research university in Baltimore, Maryland. It is the largest of Maryland's historically black colleges and universities (HBCUs). In 1867, the university, then known as the Centenary Biblical Institute, changed its name to Morgan College to honor Reverend Lyttleton Morgan, the first chairman of its board of trustees and a land donor to the college. It became a university in 1975. Morgan State is a member of Thurgood Marshall College Fund. Although a public institution, Morgan State is not part of the University System of Maryland.

Rosenwald Foundation
The Rosenwald Fund (also known as the Rosenwald Foundation, the Julius Rosenwald Fund, and the Julius Rosenwald Foundation) was established in 1917 by Julius Rosenwald and his family for "the well-being of mankind." Rosenwald became part-owner of Sears, Roebuck and Company in 1895, serving as its president from 1908 to 1922, and chairman of its board of directors until his death in 1932. History Unlike other endowed foundations, which were designed to fund themselves in perpetuity, the Rosenwald Fund was designed to expend all of its funds for philanthropic purposes before a predetermined "sunset date." It donated over $70 million to public schools, colleges and universities, museums, Jewish charities, and African American institutions before funds were completely depleted in 1948. The rural school building program for African-American children was one of the largest programs administered by the Rosenwald Fund. Over $4.4 million in matching funds stimulated construction of more ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Robert Corey
Robert Brainard Corey (August 19, 1897 – April 23, 1971) was an American biochemist, mostly known for his role in discovery of the α-helix and the β-sheet with Linus Pauling. Also working with Pauling was Herman Branson. Their discoveries were remarkably correct, with even the bond lengths being accurate until about 40 years later. The α-helix and β-sheet are two structures that are now known to form the backbones of many proteins. Academic training A childhood polio survivor, Corey received his undergraduate degree from the University of Pittsburgh, and his Ph.D. in chemistry from Cornell University (Marsh, p. 52-53). The findings of α-helix and β-sheet At Caltech, the trio (Pauling, Corey and Branson) published a series of 8 articles in the Proceedings of the National Academy of Sciences (PNAS). The most revolutionary of the 8 articles in PNAS is the one written on February 28, 1951. That date was also Pauling's 50th birthday. It was called "The Structure of Pro ...

Crystallography
Crystallography is the experimental science of determining the arrangement of atoms in crystalline solids. Crystallography is a fundamental subject in the fields of materials science and solid-state physics (condensed matter physics). The word "crystallography" is derived from the Greek word κρύσταλλος (''krystallos'') "clear ice, rock-crystal", with its meaning extending to all solids with some degree of transparency, and γράφειν (''graphein'') "to write". In July 2012, the United Nations recognised the importance of the science of crystallography by proclaiming that 2014 would be the International Year of Crystallography. denote a direction vector (in real space). * Coordinates in ''angle brackets'' or ''chevrons'' such as <100> denote a ''family'' of directions which are related by symmetry operations.

Helix
A helix () is a shape like a corkscrew or spiral staircase. It is a type of smooth space curve with tangent lines at a constant angle to a fixed axis. Helices are important in biology, as the DNA molecule is formed as two intertwined helices, and many proteins have helical substructures, known as alpha helices. The word ''helix'' comes from the Greek word ''ἕλιξ'', "twisted, curved". A "filled-in" helix – for example, a "spiral" (helical) ramp – is a surface called ''helicoid''. Properties and types The ''pitch'' of a helix is the height of one complete helix turn, measured parallel to the axis of the helix. A double helix consists of two (typically congruent) helices with the same axis, differing by a translation along the axis. A circular helix (i.e. one with constant radius) has constant band curvature and constant torsion. A ''conic helix'', also known as a ''conic spiral'', may be defined as a spiral on a conic surface, with the distance to the apex an expo ...

Linus Pauling
Linus Carl Pauling (; February 28, 1901August 19, 1994) was an American chemist, biochemist, chemical engineer, peace activist, author, and educator. He published more than 1,200 papers and books, of which about 850 dealt with scientific topics. ''New Scientist'' called him one of the 20 greatest scientists of all time, and as of 2000, he was rated the 16th most important scientist in history. For his scientific work, Pauling was awarded the Nobel Prize in Chemistry in 1954. For his peace activism, he was awarded the Nobel Peace Prize in 1962. He is one of five people to have won more than one Nobel Prize (the others being Marie Curie, John Bardeen, Frederick Sanger and Karl Barry Sharpless). Of these, he is the only person to have been awarded two unshared Nobel Prizes, and one of two people to be awarded Nobel Prizes in different fields, the other being Marie Curie.

Marie Maynard Daly
Marie Maynard Daly (April 16, 1921October 28, 2003) was an American biochemist. She was the first African-American to receive a Ph.D. from Columbia University and the first African-American woman in the United States to earn a Ph.D. in chemistry. Daly made important contributions in four areas of research: the chemistry of histones, protein synthesis, the relationships between cholesterol and hypertension, and creatine's uptake by muscle cells. Education Daly attended Hunter College High School, a laboratory high school for girls ran by Hunter College faculty, where she was also encouraged to pursue chemistry. She then enrolled in Queens College, a small, fairly new school in Flushing, New York. She lived at home to save money and graduated magna cum laude from Queens College with her bachelor's degree in chemistry in 1942. Upon graduation, she was named a Queens College Scholar, an honor that is awarded to the top 2.5% of the graduating class. Labor shortages and the need for sc ...
