RW Schaedler, R Dubos, R Costello, 'The development of bacterial flora in the gastrointestinal tract of mice', Journal of Experimental Medicine, 122/1 (1965), 59-66. 1965-07-01T00:00:00+0000Stanley was an American biochemist and virologist. In 1935 he managed to crystalise the tobacco virus, the causative agent of plant disease. This was a major breakthrough because prior to this no scientists had succeeded in finding out what viruses were. His work laid the foundation for other scientists, using x-ray diffraction, to work out the precise molecular structures and reproduction process of several viruses. During World War II he managed to purify several of the most common influenza viruses and developed a vaccine that was partly effective. In 1946 he shared the Nobel Prize for Chemistry for the 'preparation of enzymes and virus proteins in a pure form.' 1971-06-15T00:00:00+0000An American pathologist, Rous won the 1966 Nobel Prize for showing how viruses could cause cancer. He demonstrated this in 1910 by transplanting some material from a cancer tumour taken from a chicken into a healthy chicken. The healthy chicken developed cancer. Other scientists struggled to replicate his experiment in mammals so his discovery was initially dismissed. 1972-02-16T00:00:00+0000Stein was an American biochemist who shared the 1972 Nobel Prize for contributing to understanding the composition and functioning of ribonuclease, an enzyme that catalyses the break down of RNA into smaller components. It was the first structure and sequence worked out for any enzyme. Stein carried out the work with his colleague Stanford Moore in 1963. The two scientists were aided by their invention of the first means for automated amino acid analysis. In addition to his work on ribonuclease, Stein showed how proteins that are comprised of the same amino acids can have very different characteristics and functions.1980-02-02T00:00:00+0000An American biochemist, Moore helped develop the first automated amino acid analyser in 1958. The machine transformed the ability to analyse the amino acid sequences of proteins. Together with William H Stein, Moore used the machine to determine the amino acid sequence of the ribonuclease molecule. Moore shared the 1972 Nobel Prize for Chemistry for this work. 1982-08-23T00:00:00+0000Claude was a Belgian physician and cell biologist. In 1930 he developed the process of cell fractionation which involves grinding up cells to break up the membrane and their contents. The material is then placed in a centrifuge to separate out the cells's components. With the technique he was able to identify and purify the RNA from the Rous sarcoma virus which causes cancer in chickens. Claude was also one of the first to use of the electron microscope to study biological cells, which enabled him to discover that ribosomes are the power houses of all cells. In addition he helped show that all eukaryotic cells have a lace-work structure. In 1974 he shared the Nobel Prize for Medicine for discoveries concerning cell structure and function.1983-05-22T00:00:00+0000Northrop shared the 1946 Nobel Prize for Chemistry for helping to develop the technique for purifying and crystallising enzymes and virus proteins. His work showed that enzymes obey the laws of chemical reactions and that they are proteins. In 1930 he crystallised pepsin, an enzyme present in gastric juice necessary for digestion. Eight years later he isolated the first bacterial virus (bacteriophage). This he proved to be a nucleoprotein. Other enzymes that he managed to isolate and crystalise were trypsin and chymotrypsin, both important to the digestive process. 1987-05-27T00:00:00+0000Heidelberger was one of the founders of immunochemistrty, a branch of biochemistry that investigates the mammalian immune system at the molecular level. He first made his mark in 1923 when he found with Oswald Avery that that the immune system could target bacterial sugars. The two scientists made the discovery while investigating a capsular substance that envelops pneumococcus and other species of bacteria. Their work helped determine that antibodies were proteins. It also paved the way to improving the production of more effective serum therapies for the prevention of bacterial infectious like pneumonia and meningitis.1991-06-25T00:00:00+0000A geneticist by training, Sager enjoyed two careers. She first made her mark in the 1950s and 1950s when she discovered the transmission of genetic traits through chloroplast DNA. This was the first example of genetics not involving the cell nucleus. Later on she became a major pioneer in cancer genetics in the early 1970s and was one of the first to propose and investigate the function of tumour suppressor genes. 1997-03-29T00:00:00+0000Chase was an American immunologist who in the early 1940s discovered that white blood cells trigger the immune response in the body confronting a foreign invader. His finding laid to rest the belief that antibodies by themselves could protect the body from allergies and pathogens. Chase also uncovered the second arm of the immune system, known as cell-mediated immunity, paving the way to the discovery of lymphocyte cells and B and T cells.2004-01-05T00:00:00+0000Merrifield was an American biochemist and organic chemist. In 1984 he was awarded the Nobel Prize for Chemistry for inventing a process known as solid phase peptide synthesis. He developed the technique in 1965. It provided a methodology for chemical synthesis on a solid matrix. By the mid-1960s he and his team had proved the method could be used to synthesise bradykinin, angiotensin, desamino-oxytocin and insulin. In 1969 they managed to synthesise the enzyme, ribonuclease A. This was the first proof of the chemical nature of enzymes. Merrifield's method is now a rountine method for automatically synthesising large proteins, novel nucleotides, or short fragments of DNA. 2006-05-14T00:00:00+0000Palade was a Romanian-American cell biologist who helped determine cell function and organisation. He and colleagues demonstrated that all plant cells and some animal and bacteria cells have a vacuole, an enclosed compartment in the cell membrane, which contains enzymes essential to maintaining the cell's health. In 1974 he was awarded the Nobel Prize in Physiology and Medicine for his innovations in electron microscopy and cell fractionation, which laid the foundation for molecular cell biology, and his discovery of the ribosomes of endoplastic reticulum in 1955. 2008-10-07T00:00:00+0000Zinder was an American biologist who discovered how hereditary information is transferred from one organism to another. The process is known as genetic transduction. Carrying out experiments with the bacteria species Salmonella, Zinder discovered that bacteriophages, a type of virus, carry genes from one bacterium to another. He did the work with Joshua Lederberg, his doctoral supervisor. 2012-02-03T00:00:00+0000D. Bikard, L A Marrafini, 'Control of gene expression by CRISPR-Cas systems', F1000Prime Rep, 5 (2013) 47. 2013-02-01T00:00:00+0000de Duve was a cytologist and biochemist. The son of Belgian refugees who fled to England during World War I, de Duve is associated with the discovery of peroxisome and lysosome in the 1950s and 1960s. They are two specialised subunits found within the cell and are vital to the function of the cell. His work paved the way to unravelling the biology of several genetic diseases. He was awarded the Nobel Prize for Medicine in 1974 on the back of his 'discoveries concerning the structural and functional organisation of the cell.'2013-05-04T00:00:00+0000Edelman was an American biologist renowned for his research on antibodies, the body's defense against harmful foreign substances like viruses and bacteria. His research helped determine the chemical structure of antibodies in the early 1960s. It showed that antibodies were made up of two light and heavy chains linked together by disulfide bonds. The breakthrough immediately galvanised feverish activity in all fields of immunological science, paving the way to the development of antibodies for both diagnostics and therapy. Edelman was awarded the Nobel Prize for Medicine in 1972 for his work. 2014-05-17T00:00:00+0000
