Chemistry Wallach was born in Königsberg, the son of a Prussian
Chemistry Wallach was born in Königsberg, the son of a Prussian civil servant. In 1867 he started studying chemistry at the University of Göttingen, where at this time Friedrich Wöhler was head of organic chemistry. After one semester at the University of Berlin with August Wilhelm von Hofmann, Wallach received his Doctoral degree from the University of Göttingen in 1869, and worked as a Professor in the University of Bonn (1870–89) and the University of Göttingen (1889– 1915). Wallach died at Göttingen. Otto Wallach Born: 27 March 1847, Koenigsberg (now Kaliningrad), Germany (now Russia) Died: 26 February 1931, Göttingen, Germany Affiliation at the time of the award: Goettingen University, Göttingen, Germany Prize motivation: "in recognition of his services to organic chemistry and the chemical industry by his pioneer work in the field of alicyclic compounds" Field: industrial chemistry, organic chemistry During his work with Friedrich Kekulé in Bonn he started a systematic analysis of the terpenes present in essential oils. Up to this time only a few had been isolated in pure form, and structural information was sparse. Melting point comparison and the measurement of mixtures was one of the methods to confirm identical substances. For this method the mostly liquid terpenes had to be transformed into crystalline compounds. With stepwise derivatisation, especially additions to the double bond present in some of the terpenes, he achieved the goal of obtaining crystalline compounds. The investigation of the rearrangement reactions of cyclic unsaturated terpenes made it possible to obtain the structure of an unknown terpene by following the rearrangements to a known structure of a terpene. With these principal methods he opened the path to systematic research on terpenes. He was responsible for naming terpene and pinene, and for undertaking the first systematic study of pinene .He wrote a book about the chemistry of terpenes, "Terpene und Campher" (1909). Otto Wallach is known for Wallach's rule, Wallach degradation, the Leuckart-Wallach reaction (which he developed along with Rudolf Leuckart) and the Wallach rearrangement. Otto Wallach was a German chemist and recipient of the 1910 Nobel Prize in Chemistry for his work on alicyclic compounds. Botany: Zingiber nimmonii (Grah.) Dalz. In Hook. Kew J.

Microbiology :- Frank Macfarlane Burnette: (1899-1985) - He was a Australian virologist best known for his contributions to immunology. In 1960 He won the Nobel prize for predicting acquired immune tolerance and was best known for developing the theory of clonal selection. He discover causative agent of Q-fever and psittacosis. He also develope assays for the isolation , cultivation and detection of influenza virus. He describe the recombination of influenza strains. The modern method for production of influenza vaccine is based on Burnets work. In 1926 He was awarded the Beit Memorial Felllowship by the Lister institute. In 1956 he led to the development of clonal selection, thus forming one of the concepts of immunology known as Burnet’s clonal selection therapy. Zoology: - Karl Landsteiner Karl Landsteiner, (June 14, 1868 – June 26, 1943), was an Austrian and American biologist and physician.[2] He is noted for having first distinguished the main blood groups in 1900 (however, Jan Janský described and distinguished main blood groups before him), having developed the modern system of classification of blood groups from his identification of the presence of agglutinins in the blood, and having identified, with Alexander S. Wiener, the Rhesus factor, in 1937, thus enabling physicians totransfuse blood without endangering the patient′s life. With Constantin Levaditi and Erwin Popper, he discovered the polio virus in 1909. He received the Aronson Prize in 1926. In 1930 he received the Nobel Prize in Physiology or Medicine. He was awarded aLasker Award in 1946 posthumously and is recognized as the father of transfusion medicine.

Born in Sweden, he was raised in the shadow of his father, an astronomy professor. Anders showed an extraordinary talent in mathematics from childhood and after completing his education, decided to become an astronomer. He made earlier observations concerning aurora borealis (northern lights) and is regarded as the first astronomer to suggest a connection between aurora borealis and changes in the Earth's magnetic field. He also assessed the brightness of stars with measuring tools. Later, he participated in an expedition which proved the Newton’s theory that the Earth has the shape of an ellipsoid, flattened at the poles. After succeeding in the expedition, he laid the foundation of Uppsala Astronomical Observatory, the oldest astronomical observatory in Sweden. However, he is most famous for the temperature scale he proposed based on the boiling and freezing points of water. Later on, a reversed form of his original design was adopted as the standard and used in almost all the scientific works. He started many other research projects but died unexpectedly before he could complete most of them. He was an extraordinary astronomer, and as a tribute to his accomplishments, the standard unit on the temperature scale, “Celsius”, is named after him. Major Works He was the first person who suggested a connection between the aurora borealis and changes in the Earth's magnetic field. He advocated the measurement of an arc of a meridian in Lapland and later took part in an expedition which helped in verification of Newton’s theory that the Earth is flattened at the poles. He was the first to perform and publish careful experiments seeking to define an international temperature scale based on scientific grounds. In 1742, he proposed a temperature scale based on the boiling and freezing points of water, which was the reverse of the scale now known by the name ‘Celsius’. Awards & Achievements ‘Celsius’, also known as centigrade, a scale and unit of measurement for temperature, is named after him.
