Jerome Berson
Jerome A. Berson (May 10, 1924 – January 13, 2017) was an American chemist who was a Sterling Professor at Yale University, and also a published author. He worked on sigmatropic rearrangements, thermal and carbocationic rearrangements, and the role of orbital symmetry in chemical reactions while at University of Wisconsin. While at Yale University, he was part of many new studies, especially on non-Kekulé molecules. Early life and education Jerome Berson was born in Sanford, Florida, to immigrant parents. His father served as a lay rabbi and his mother was a milliner and housewife. As a result of the Great Depression, his parents struggled to earn a living so they moved to The Bronx, New York in 1934 when Berson was about ten years old and stayed there until 1937. During this time Berson attended Junior High School. In 1937 his family relocated to Long Island, where he attended Long Island High School. Berson graduated high school at the age of 15. He worked riding a Good ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sanford, Florida
Sanford is a city and the county seat of Seminole County, Florida, United States. It is located in Central Florida and its population was 61,051 as of the 2020 census. It is part of the Orlando–Kissimmee–Sanford Metropolitan Statistical Area. Known as the "Historic Waterfront Gateway City", Sanford sits on the southern shore of Lake Monroe at the head of navigation on the St. Johns River. Native Americans first settled the area thousands of years before the city was formed. The Seminoles arrived in the area in the 18th century. During the Second Seminole War in 1836, the United States Army established Camp Monroe and built a road now known as Mellonville Avenue. Sanford is about northeast of Orlando. Sanford is home to Seminole State College of Florida and the Central Florida Zoo and Botanical Gardens. Its downtown attracts tourists with shops, restaurants, a marina, and a lakefront walking trail called the Sanford Riverwalk. The Orlando Sanford International A ...

Non-Kekulé Molecule
A non-Kekulé molecule is a conjugated system, conjugated hydrocarbon that cannot be assigned a classical Kekulé structure. Since non-Kekulé molecules have two or more formal charges or radical (chemistry), radical centers, their Spin (physics), spin-spin interactions can cause electrical conductivity or ferromagnetism (molecule-based magnets), and applications to functional materials are expected. However, as these molecules are quite reactive and most of them are easily decomposed or Polymerization, polymerized at room temperature, strategies for stabilization are needed for their practical use. Synthesis and observation of these reactive molecules are generally accomplished by matrix-isolation methods. Biradicals The simplest non-Kekulé molecules are biradicals. A biradical is an even-electron chemical compound with two free radical centres which act ''independently'' of each other. They should not be confused with the more general class of diradicals. One of the first bir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Academy Of Arts And Sciences
The American Academy of Arts and Sciences (The Academy) is one of the oldest learned societies in the United States. It was founded in 1780 during the American Revolution by John Adams, John Hancock, James Bowdoin, Andrew Oliver, and other Founding Fathers of the United States. It is headquartered in Cambridge, Massachusetts. Membership in the academy is achieved through a nominating petition, review, and election process. The academy's quarterly journal, '' Dædalus'', is published by the MIT Press on behalf of the academy, and has been open-access since January 2021. The academy also conducts multidisciplinary public policy research. Laurie L. Patton has served as President of the Academy since January 2025. History The Academy was established by the Massachusetts legislature on May 4, 1780, charted in order "to cultivate every art and science which may tend to advance the interest, honor, dignity, and happiness of a free, independent, and virtuous people."

Erich Hückel
Erich Armand Arthur Joseph Hückel (August 9, 1896, Berlin – February 16, 1980, Marburg) was a German physicist and physical chemist. He is mainly known for the Debye–Hückel theory of electrolytic solutions and the Hückel method of approximate molecular orbital (MO) calculations on π electron systems. Hückel was born in the Charlottenburg suburb of Berlin. He studied physics and mathematics from 1914 to 1921 at the University of Göttingen. On receiving his doctorate, he became an assistant at Göttingen, but soon became an assistant to Peter Debye at Zürich. It was there that he and Debye developed their theory (the Debye–Hückel theory, in 1923) of electrolytic solutions, elucidating the behavior of strong electrolytes by considering interionic forces, in order to account for their electrical conductivity and their thermodynamic activity coefficients. After spending 1928 and 1929 in England and Denmark, working briefly with Niels Bohr, Hückel joined the faculty ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert Burns Woodward
Robert Burns Woodward (April 10, 1917 – July 8, 1979) was an American organic chemist. He is considered by many to be the preeminent synthetic organic chemist of the twentieth century, having made many key contributions to the subject, especially in the synthesis of complex natural products and the determination of their molecular structure. He worked closely with Roald Hoffmann on theoretical studies of chemical reactions. He was awarded the Nobel Prize in Chemistry in 1965. Early life and education Woodward was born in Boston, Massachusetts, on April 10, 1917. He was the son of Margaret Burns (an immigrant from Scotland who claimed to be a descendant of the poet, Robert Burns) and her husband, Arthur Chester Woodward, himself the son of Roxbury apothecary, Harlow Elliot Woodward. His father was one of the many victims of the 1918 influenza pandemic. From a very early age, Woodward was attracted to and engaged in private study of chemistry while he attended a public p ...
