The Pedersen Memorial Issue
springer.com Chemistry : Organic Chemistry The Pedersen Memorial Issue Foreword: Charles J. Pedersen (1904-1989), Nobel Laureate in Chemistry (1987) This issue is dedicated to the memory of the late Charles J. Pedersen in recognition of his outstanding contribution to scientific research, culminating in his discovery of crown ethers and their remarkable cation complexing properties and his receipt of the 1987 Nobel Prize in Chemistry. Charlie's origin and early years in Korea did not portend the creative work in chemistry which would characterize his later life. However, we can see in his early years the influence of his Norwegian father and Japanese mother who considered his formal education to be of utmost importance. At the age of eight, he was sent abroad to Japan for schooling, first at a convent school in Nagasaki, and two years later at a French-American preparatory school in Yokohama run by a Marianist order of Catholic priests and brothers. The latter group encouraged him to attend the order's University of Dayton in Ohio where he received a bachelors degree in Springer chemical engineering. Charlie's academic experiences, his employment with du Pont, and the Softcover reprint of the creative spark which he manifested at an early stage of his scientific career are detailed in the 1st original 1st ed. 1992, VI, paper in this issue by Herman Schroeder. Schroeder had a long-time association with Charlie at edition 406 p. du Pont as a co-worker, supervisor, and friend. His recollections provide insight into Charlie's creative mind. In addition, they make it clear that a long period of creative work preceded the accidental discovery of the first synthetic crown ether.

DUNITZ INUS CARL PAULING was born in Portland, Oregon, on LFebruary 28, 1901, and died at his ranch at Big Sur, California, on August 19, 1994. In 1922 he married Ava Helen Miller (died 1981), who bore him four children: Linus Carl, Peter Jeffress, Linda Helen (Kamb), and Edward Crellin. Pauling is widely considered the greatest chemist of this century. Most scientists create a niche for themselves, an area where they feel secure, but Pauling had an enormously wide range of scientific interests: quantum mechanics, crys- tallography, mineralogy, structural chemistry, anesthesia, immunology, medicine, evolution. In all these fields and especially in the border regions between them, he saw where the problems lay, and, backed by his speedy assimilation of the essential facts and by his prodigious memory, he made distinctive and decisive contributions. He is best known, perhaps, for his insights into chemical bonding, for the discovery of the principal elements of protein secondary structure, the alpha-helix and the beta-sheet, and for the first identification of a molecular disease (sickle-cell ane- mia), but there are a multitude of other important contri- This biographical memoir was prepared for publication by both The Royal Society of London and the National Academy of Sciences of the United States of America.

The 2009 Lindau Nobel Laureate Meeting: Roger Y. Tsien, Chemistry 2008. J. Vis. Exp. (35), e1575, doi:10.3791/1575 (2010). Abstract American biochemist Roger Tsien shared the 2008 Nobel Prize in Chemistry with Martin Chalfie and Osamu Shimomura for their discovery and development of the Green Fluorescent Protein (GFP). Tsien, who was born in New York in 1952 and grew up in Livingston New Jersey, began to experiment in the basement of the family home at a young age. From growing silica gardens of colorful crystallized metal salts to attempting to synthesize aspirin, these early experiments fueled what would become Tsien's lifelong interest in chemistry and colors. Tsien's first official laboratory experience was an NSF-supported summer research program in which he used infrared spectroscopy to examine how metals bind to thiocyanate, for which he was awarded a $10,000 scholarship in the Westinghouse Science Talent Search. Following graduation from Harvard in 1972, Tsien attended Cambridge University in England under a Marshall Scholarship. There he learned organic chemistry --a subject he'd hated as an undergraduate-- and looked for a way to synthesize dyes for imaging neuronal activity, generating BAPTA based optical calcium indicator dyes. Following the completion of his postdoctoral training at Cambridge in 1982, Tsien accepted a faculty position at the University of California, Berkeley.

Professor Ada Yonath, Weizmann Institute of Science, Rehovot, Israel, Nobel Laureate in Chemistry, 2009
1 Public Health Reviews, Vol. 34, No 2 Preface: Science and Public Health: Professor Ada Yonath, Weizmann Institute of Science, Rehovot, Israel, Nobel Laureate in Chemistry, 2009 Lore Leighton1 ABSTRACT Ribosomes are responsible for translating genetic code into protein and thus central components of cell life. Knowledge of their structure provided important potential applications in and understanding of the mode of action of antibiotics and resistance to antibiotics. The work of Professor Ada Yonath on the crystallography of ribosomes led to improvements in crystallization, crystallographic techniques, and x-ray diffraction detection procedures. In 2000 and 2001, Dr. Yonath published the three dimensional structures of the two subunits of bacterial ribosome. There are potential applications for this work, and hopefully science will use such tools to develop new methods to reduce the burden of many diseases. In 2009, Professor Ada Yonath was awarded the Nobel Prize in Chemistry for her structural work on the ribosome. Key Words: Nobel Prize Chemistry 2009, Professor Ada Yonath, Weizman Institute Israel, ribosome, x-ray crystallography, antibiotic resistance, science and public health Recommended Citation: Leighton, L.

Synthesis of Quinine
Synthesis of quinine Outstanding organic chemist Robert Burns Woodward over 30 years has carried out about 20 complex syntheses of natural compounds such as quinine, cholesterol, cortisone, strychnine, lysergic acid, reserpine, chlorophyll, cephalosporin, and colchicine that previously seemed unrealizable. For his contribution in organic chemistry he was awarded the Robert Burns Woodward Nobel Prize in Chemistry in 1965. The goal of one of the first in a series of April 10, 1917 – July 8, 1979 extremely complex and elegant syntheses he carried out was quinine, an alkaloid of the cinchona tree with a bitter taste. Quinine has antipyretic, analgesic, and antiarethmic properties and is still used in the treatment of malaria. Although the synthesis proved to be successful, it was too long and laborious to be applied on a practical scale. Later, E. Jacobsen and his co- workers were able to propose a much simpler enanteoselective synthesis of quinine using catalytic reactions. Steven E.

Multistep Synthesis of Complex Carbogenic Molecules
THE LOGIC OF CHEMICAL SYNTHESIS: MULTISTEP SYNTHESIS OF COMPLEX CARBOGENIC MOLECULES Nobel Lecture, December 8, 1990 by E LIAS J AMES C OREY Department of Chemistry, Harvard University, Cambridge, Massachusetts, USA Carbogens, members of the family of carbon-containing compounds, can exist in an infinite variety of compositions, forms and sizes. The naturally occurring carbogens, or organic substances as they are known more tradi- tionally, constitute the matter of all life on earth, and their science at the molecular level defines a fundamental language of that life. The chemical synthesis of these naturally occurring carbogens and many millions of unnatural carbogenic substances has been one of the major enterprises of science in this century. That fact is affirmed by the award of the Nobel Prize in Chemistry for 1990 for the “development of the theory and methodology of organic synthesis”. Chemical synthesis is uniquely positioned at the heart of chemistry, the central science, and its impact on our lives and society is all pervasive. For instance, many of today’s medicines are synthetic and many of tomorrow’s will be conceived and produced by synthetic chemists. To the field of synthetic chemistry belongs an array of responsibilities which are crucial for the future of mankind, not only with regard to the health, material and economic needs of our society, but also for the attainment of an understanding of matter, chemical change and life at the highest level of which the human mind is capable. The post World War II period encompassed remarkable achievement in chemical synthesis. In the first two decades of this period chemical syntheses were developed which could not have been anticipated in the earlier part of this century.

Fifty Years Ago: Linus Pauling and the Belated Nobel Peace Prize Peter C. Agre RADUATE students have approached me on multiple occasions to inquire Gabout pursuing a career in science diplomacy. My first reaction is to fire back, “And so how is it going in the lab?” This often provokes embarrassment and an occasional confession about the frustrations of being a graduate student. On other occasions I think their questions were primed by the idealism of doing something with importance far beyond the laboratory. Is it possible that extracurricular activities efforts outside of the laboratory might have special value? And to what extent is the credibility in the lab essential for extracurricular attention? It seemed likely that the international network of scientists who know other scientists represents unique opportunities to use science to foster friendships worldwide. This has caused me to reflect on the many interesting people I have encountered during my career in science. A few were particularly inspirational, and of these, Linus Pauling, the fascinating and colorful American scientist, stands out for opening doors both worldwide and here in the United States.

Evolution in Chemistry the Power of Evolution Is Revealed Through the Diversity of Life
THE NOBEL PRIZE IN CHEMISTRY 2018 POPULAR SCIENCE BACKGROUND A (r)evolution in chemistry The power of evolution is revealed through the diversity of life. The Nobel Prize in Chemistry 2018 is awarded to Frances H. Arnold, George P. Smith and Sir Gregory P. Winter for the way they have taken control of evolution and used it for the greatest beneft to humankind. Enzymes developed through directed evolution are now used to produce biofuels and pharmaceuticals, among other things. Antibodies evolved using a method called phage display can combat autoimmune diseases and, in some cases, cure metastatic cancer. We live on a planet where a powerful force has become established: evolution. Since the frst seeds of life appeared around 3.7 billion years ago, almost every crevice on Earth has been flled by organisms adapted to their environment: lichens that can live on bare mountainsides, archaea that thrive in hot springs, scaly reptiles equipped for dry deserts and jellyfsh that glow in the dark of the deep oceans. In school, we learn about these organisms in biology, but let’s change perspective and put on a chemist’s glasses. Life on Earth exists because evolution has solved numerous complex chemical problems. All organisms are able to extract materials and energy from their own environmental niche and use them to build the unique chemical creation that they comprise. Fish can swim in the polar oceans thanks to antifreeze proteins in their blood and mussels can stick to rocks because they have developed an underwater molecular glue, to give just a few of the innumerable examples.

“The Best Way to Have a Good Idea Is to Have Lots of Ideas.” John Kirwan Emeritus Professor of Rheumatic Diseases
Putting Linus Pauling's dictum into practice: “The best way to have a good idea is to have lots of ideas.” John Kirwan Emeritus Professor of Rheumatic Diseases [email protected] Linus Pauling (1901-1994) • American chemist, biochemist, peace activist, author, and educator. • One of the founders of the fields of quantum chemistry and molecular biology. • Awarded the Nobel Prize in Chemistry in 1954 and the Nobel Peace Prize in 1962. • Only two people have been awarded Nobel Prizes in different fields, the other being Marie Skłodowska-Curie (Physics 1903, Chemistry 1911). Linus Pauling (1901-1994) The Pauling Principle: • The best way to have a good idea is to have a lot of ideas and throw away the bad ones. This implies at least two things: • one must be willing to generate many ideas • one must be willing to generate bad ideas John’s ideas • Since late 1994 I have made a separate folder in my computer storage for each idea I started on • I found 186! John’s ideas • I went back through every folder and discovered • The date of the first file entry • How much work I did on that idea/project • What came out of it How much work? • From the number of files stored, and from memory, I estimated this on a 1 to 10 scale 1 – Just an initial proposal or email exchange, no follow up files 10 – Lots and lots of files, emails, notes of meetings, records of draft grant applications, draft papers, hours of soul searching… What came out of it? • I invented a classification scale: Maximum Output O utcomes 1993 1994 Outcomes at Dec 2015 by year project
