1920-1929

Vincent- 1921

**Frederick Soddy**
Ironically, Frederick Soddy received his 1921 Nobel Prize for chemistry a year later, 1922 due to his insufficient discovery in 1921. Born in England, Soddy was raised by wealthy merchants who provided quality education. With decent education, Soddy graduated from Oxford in 1899, and had been a professor at Oxford from 1919 to 1936. After the graduation from Oxford, Soddy moved to McGill University in Canada, and worked with professor Ernest Rutherford on radioactivity. Together they concluded that radioactivity is a phenomenon that involves atomic disintegration to create something new. They also investigated the gaseous product of radium. After his study in Canada Soddy moved back to England and studied more about radioactivity. While his experiment with alpha particle he discovered that atom can move 2 places back in the periodic table which later was called isotope. With the discovery of isotope, Soddy tried to find more about isotopes in the radio active atoms, and later he discovered radioisotopes which he got Nobel Prize for. . []

Alex- 1922 Francis W. Aston (1877-1945), winner of the 1922 Nobel Prize for Chemistry, was a chemist and physicist who discovered isotopes and invented the mass spectrograph.

He was born in England in September 1877 to a farmer and metal merchant named William Aston. As a child, he attended the local vicarage school before being sent to a boarding school to finish his high school education. In 1893 he began to study chemistry at the nearby Macon Science College. From 1896 on, he performed organic chemistry research in a laboratory in his father’s house, studying tartaric acid compounds before graduating from college and learning fermentation chemistry, working for a brewing chemistry for several years, starting in 1900, During this time he began to get interested in physics, and he invented several new types of pumps. He began to research X-rays and radioactivity, which had just been discovered, and in 1908 he moved to the prestigious Cavendish Laboratory in Cambridge, having been invited by the distinguished physicist J.J. Thompson, discoverer of the electron.

Thompson and Aston performed groundbreaking research on methods of separating ions according to their charge and mass. In 1914, the work had to be halted due to World War I, and Aston went to work for the Royal Air Force developing aerodynamic coatings for airplanes. After the war, in 1919, he completed work on the first mass spectrometer, a device for measuring the mass-to-charge ratio of charged particles. Mass spectrometers can be used to determine the masses of particles, find the elemental composition of a sample, and study the chemical structures of some types of compounds. Using his spectrometer, he was able to prove the existence of isotopes of the element neon, and then went on to find 212 other isotopes of various elements. In 1920, following up on his work with isotopes, he formulated the whole-number rule, which states that if the mass of the oxygen isotope is defined as 16, the masses of all other isotopes will be very nearly whole numbers.

His discoveries brought him widespread acclaim, and in 1921 he was made a member of the Royal Society. In 1922 he received his Nobel Prize, for “his discovery, by means of his mass spectrograph, of isotopes, in a large number of non-radioactive elements, and for his enunciation of the whole-number rule.”

All of this recognition allowed him to devote more time to leisure, and he travelled widely in the next few years. He was a highly talented musician and also cross-country skied, climbed, skated, raced automobiles, cycled, swam, played tennis, golfed, and surfed. He visited many countries in order to observe lunar eclipses. In his spare time, he wrote three popular books: //Isotopes,//  in 1922, //Structural Units of the Material Universe// , in 1923, and //Mass-Spectra and Isotopes,// in 1933. In 1945, he died, at Cambridge. A crater on the moon is now named after him.

Brittany- 1923 Fritz Pregl

Fritz Pregl is an Austrian chemist born on September 3, 1869 in Laibach, which is now known as Yugoslavia. In Laibach, Pregl went to grammar school, but when his father died, who was a bank official, he and his mother moved to Graz. In Graz, he went to school at the University of Graz, and he began to study medicine. He received his M.D in 1894. But while in school, Pregl was an assistant lecturer to Alexander Rollett, in the histology and physiology departments, While in this position, Pregl attained much knowledge on the many concepts of chemistry and also from Professor Skraup, and he then took over the chair when Alexander Rollett died in 1903.

In 1904, went to Germany, where he studied for short periods under Gustav v. Hüfner in Tübingen, W. Ostwald in Leipzig and Emil Fischer in Berlin. At this time, Pregl began research on bile acids, but could not fully complete his experiment at this time due to tiny amounts. So afterwards he went back to Graz and went to the Medico-Chemical Institute under K.B. Hofmann and was appointed forensic chemist for the Graz circuit in 1907. In Graz, he analyzed bile acids, and he started investigating the components of albuminous bodies. Because he had limited starting materials, he began to look for methods where you could use smaller amounts when making quantitative analyses of elements in compounds.

The years 1910-1913, Pregl was a professor at Innsbruck University, and devoted his time to developing the method of quantitative organic micro-analysis. Pregl continued with this work when he was recalled to Graz University in 1913; he was appointed Dean of the Medical Faculty for the year 1916-1917 and Vice-Chancellor of Graz University for 1920-1921.

And soon, furthering his investigation, Pregl,using his own methods of quantitative micro-analysis, was able to make measurements of carbon, hydrogen, nitrogen, sulphur, and halogen, using only 5-13 mg of starting materials with results as accurate as those obtained by MACRO-analysis. Pregl also contributed a number of micromethods for measuring atomic groups and developed a series of apparatus. Pregl was awarded to Nobel Prize in 1923. His discoveries were essential in the medical and chemistry fields. And he made it possible to determine quantitatively the elements in organic compounds in samples weighing less (3-5 milligrams) than was required in the procedures.

﻿ Theodor H.E. Svedberg received the Nobel Prize in chemistry in 1926 for his work on disperse systems. Theodor Svedberg was born at Fleräng, Valbo, in the county of Gävleborg, Sweden on August 30, 1884. His father, Elias Svedberg, was a manager of works. Before he began to associate with Uppsala University in 1904, he attended the Köping School, the Örebro High School and Gothenburg Modern School. He was an eminent professor at the Uppsala University as elected professor of physical chemistry. He gained his Bachelor of Arts degree, Master’s degree and Doctor of Philosophy. Also, he was a professor at the University of Uppsala. He was not only concerned with disperse system but also concerned with colloids and macromolecular compounds. Specifically, he was concerned with physical properties of colloids as diffusion, light absorption, and sedimentation. In this way, he developed new method of producing colloid particles and theory founded by Einstein and Von Smoluchowski on the Brownian movements which led him to have final definite proof of the existence of molecules. Brownian movement is simply described as irregular motion by particles of matter when it stopped in a fluid. He published many books as //ie Methoden zur Herstellung kolloider Lösungen anorganischer Stoffe//, //Die Existenz der Moleküle//, //Colloid Chemistry//, //The Ultracentrifuge//. He also wrote and published many books in Swedish //Materien//, //Arbetets dekadens// and //Forskning och Industri//. Disperse system is one substance is distributed throughout a second substance and each state can be solid, liquid and gas forms. Disperse system is divided into three parts: true solution, colloids, and coarse dispersion. First of all, true solution is molecular dispersion, and the particles are invisible. Secondly, Colloid dispersion is an intermediate state between true solutions and coarse dispersion. The particles also cannot be seen in this state. It has very high surface area so particles diffuse more slowly than those of true solutions. The last one is coarse dispersion and it is also called as suspensions or emulsions. In this state, the particles are often visible with our eyes. Theodor Svedberg also invented analytical ultracentrifugation which leads to the discovery of proteins that protein is originally composed of a huge number of atoms by covalent bonds. The analytical ultracentrifugation leads to more understanding of macromolecules.  <span style="background-color: transparent; color: #000099; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; vertical-align: baseline;">__[]__ <span style="background-color: transparent; color: #000099; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; vertical-align: baseline;">__[]__ []

Kai- 1927 Heinrich Wieland was born in Germany on June 4, 1977 to Dr. Theodore Wieland and Elise Blum. His father was a renowned pharmaceutical chemist and many say that he is the one who inspired to pursue a career in Chemistry. Heinrich loved Chemistry so much that he studied at the Universities of Munich, Berlin, and Stuttgart focusing on that subject. After acquiring a great deal of knowledge on the subject of Chemistry, he went on to study at the Baeyer Laboratory in Munich where, in 1901, he received his doctorate under Johannes Thiele, who was a prominent professor of Chemistry at the University of Munich. He influenced Heinrich to focus on Chemistry, and try to contribute to the growing subject. In the beginning of his career as a chemist, Heinrich focused on organic nitrogenous compounds. This subject and researched heavily by Johannes Thiele and many believe that Thiele is the reason Heinrich started focusing on that aspect of chemistry for the beginning of his career. His brilliant studies of the reaction of nitrogen oxides with orefins and aromatics led him to being the first to produce stable organic nitrogen radicals. However, Heinrich began to focus more on the chemistry of natural substances. In studying this field, he made many contributions to the subject of Chemistry. He clarified the structure of morphine and strychnine, the constitution and synthesis of the lobelia alkaloid, and even did research on the curare alkaloid. While working on the pigment of butterflies, he discovered the biologically important class of pterin compound which led to the publication of the importance of bile acids. He won a 1927 Nobel Prize for research on bile acids which showed that the three acids then isolated had similar structures and were also structurally related to  cholesterol. He also found that different forms of nitrogen in organic compounds can be detected and distinguished from each other, an important contribution to structural organic chemistry. Wieland's theory that oxidation in living tissues occurs through removal of hydrogen atoms, not addition of oxygen, was of great importance to physiology, biochemistry, and medicine. Heinrich was also a close friend of the winner of the 1928 Nobel Prize in Chemistry, Adolf Windaus. Windaus expanded Wieland’s research on bile acids and showed that bile acids were closely related to sterols. Wieland also received the Order of Merit, and the Otto Hahn Prize. One of his greatest achievements also involved in finding the rare molecule Haefnerios which may disturb the electrical signals in the humans brain. It was found at the research of the Swedish institute of Uppsala and is mostly common in mental damaged persons.

His affiliation at the time of the award was London University. His main field is biochemistry. <span style="font-family: Arial,Helvetica,sans-serif; font-size: 12px; line-height: 15px;">His classic study of the chemistry of the fermentation of sugar by yeast juice, which have advanced the knowledge of the processes of intermediary metabolism in all living forms, lasted for many years and provided a stepping-stone for many research workers in allied fields. Harden himself contributed to the vitamin field with a series of papers on the antiscorbutic and antineuritic vitamins and their occurrence in food and drinks. He died on 17 June 1940 in Bourne of the United Kingdom. **<span style="font-family: Arial,Helvetica,sans-serif; font-size: 12px; line-height: 15px;">H <span style="font-family: Arial,Helvetica,sans-serif; font-size: 12px; font-weight: normal; line-height: 15px;">is father was Albert Tyas Harden and his mother Eliza Macalister. He was educated at a private school in Victoria Park (1873-1877) and at Tettenhall College, Staffordshire (1877-1881). He entered The Owens College in the University of Manchester in 1882, studying under Sir H.E. Roscoe, and graduated in 1885 with first-class honours in chemistry. In 1886 he was awarded the Dalton Scholarship in Chemistry and he spent twelve months during 1887-1888 working with [|Otto Fischer] at Erlangen. He returned to Manchester as lecturer and demonstrator, and remained until 1897 when he was appointed chemist to the newly founded British Institute of Preventive Medicine, which later became the Lister Institute. In 1907 he was appointed Head of the Biochemical Department, a position which he held until his retirement in 1930, and in 1912 he received the title of Emeritus Professor of Chemistry, University of London. He continued his scientific work at the Institute after his retirement. ==

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 12px; line-height: 15px;">Before he went to London, Harden had studied the action of light on mixtures of carbon dioxide and chlorine. He entered the Institute with an excellent chemical background and applied his methods to the investigation of biological phenomena (among others: the chemical action of bacteria and alcoholic fermentation). He studied the breakdown products of glucose but he was soon to be drawn to the problem of the chemistry of the yeast cell. His classic study of the chemistry of the fermentation of sugar by yeast juice, which have advanced the knowledge of the processes of intermediary metabolism in all living forms, lasted for many years and provided a stepping-stone for many research workers in allied fields. Harden himself contributed to the vitamin field with a series of papers on the antiscorbutic and antineuritic vitamins and their occurrence in food and drinks.

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 12px; line-height: 15px;">Harden was Joint Editor (with W.M. Bayliss) of //The Biochemical Journal// from 1913 to 1938, and, in addition wrote numerous papers in scientific journals. He is the author of //Alcoholic Fermentation//, //A New View of the Origin of Dalton's Atomic Theory//, and //Chemistry for Advanced Studies// (with Sir H.E. Roscoe), //Inorganic Chemistry for Advanced Students//, and //An Elementary Course of Practical Organic Chemistry// (with F.C. Garrett).

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 12px; line-height: 15px;">Harden was knighted in 1926. He was honorary Doctor of Science, University of Athens and honorary Doctor of Laws, Universities of Manchester and Liverpool. A Fellow of the Royal Society (1909), he received the Davy Medal in 1935.

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 12px; line-height: 15px;">He married Georgina Sydney Bridge, daughter of C. Wynyard Bridge of Christchurch, New Zealand, in 1900. They had no children. His wife died in January, 1928, and Sir Arthur on June 17, 1940, at his home in Bourne End, Buckinghamshire. Arthur Harden(United Kingdom) Hans von Euler-Chelpin(Sweden)


 * Hans von Euler-Chelpin was born on February 15, at Augsburg of Germany.His affiliation at the time of the award was Stockholm University in Stockholm of Sweden. His main field is also biochemistry.**<span style="font-family: Arial,Helvetica,sans-serif; font-size: 12px; line-height: 15px;">His father, who was then a captain in the Royal Bavarian Regiment, was transferred to Munich and von Euler-Chelpin spent most of his childhood not far away with his grandmother at Wasserburg. After going to school at Munich, Wurzburg and Ulm, he studied art from 1891 until 1893 at the Munich Academy of Painting, first under Schmid-Reutte and later under Lenbach, whose gifted and powerful personality greatly influenced him. His desire to study problems of colour and especially the colour of the spectrum led von Euler-Chelpin to begin, in 1893, the study of science.

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 12px; line-height: 15px;">He therefore went to the University of Berlin to study chemistry under [|Emil Fischer] and A. Rosenheim, and physics under E. Warburg and [|Max Planck] ; and in 1895 he took his doctorate at the University of Berlin.

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 12px; line-height: 15px;">He then took a short course in physical chemistry in Berlin and went, after this, to the University of Göttingen to work from 1896 until 1897 under [|W. Nernst]. In the summer of 1897 he went to work in the laboratory of [|Svante Arrhenius] in Stockholm and was appointed assistant there. In 1898 he qualified as Privatdozent in physical chemistry in the Royal University at Stockholm, and in 1899 he was appointed as such in that University. Between 1899 and 1900 he visited the laboratory of [|van 't Hoff]. Both van 't Hoff and Nernst greatly influenced his scientific development.

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 12px; line-height: 15px;">Subsequently, visits to the laboratories of A. Hantzsch and J. Thiele confirmed his interest in organic chemistry and he then began to work on this subject, partly in collaboration with Astrid Cleve, who was his wife at that time. During this period he visited the laboratories of [|E. Buchner] in Berlin and G. Bertrand at the Pasteur Institute in Paris.

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 12px; line-height: 15px;">In 1906 he was appointed Professor of General and Organic Chemistry in the Royal University, Stockholm. In 1929 the Knut and Alice Wallenberg Foundation and the International Education Board of the Rockefeller Foundation established in Stockholm the Vitamin Institute and Institute of Biochemistry, and von Euler-Chelpin was appointed as its Director. In 1941 he retired from teaching, but continued his researches.

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 12px; line-height: 15px;">Von Euler-Chelpin's first biochemical work was published in 1904. Its subject was the action of enzymes considered in relation to his earlier work on catalysis. This earlier work had won him, in 1898 the Lindblom Prize of the German Academy of Sciences for a paper on the catalytic hydrolysis of substrates by salt formation with the catalyst, work which he later developed further in collaboration with E. Rudberg and A. Ölander. From 1906 onwards, von Euler-Chelpin was chiefly concerned with physico-chemical and biochemical problems, publishing, from 1908 to 1909, the results of his work on the chemistry of plants, and in 1915 the results of his collaboration with P. Lindner on the chemistry of the fungi. From 1925 until 1930 he worked on the chemistry of enzymes.

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 12px; line-height: 15px;">An important part of von Euler-Chelpin's work was done in collaboration with K. Josephson on the enzymes saccharase and catalase. The work he had begun in 1905 on fermentation was specialized in his Institute to phosphorylation, and the first phases of fermentation and their catalysis were studied, with special attention to co-zymase and also related activators. In this latter work K. Myrback played a great part. An important result of his work with his collaborators on co-zymase was his clarification of its structure, other conclusions being confirmed by [|Lord Todd] in 1956.

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 12px; line-height: 15px;">In 1924 von Euler-Chelpin began his numerous studies of the vitamins in collaboration with B. von Euler, Paul Karrer and Margareta Rydbom, with whom he carried out, in 1928 a study of the marked vitamin A activity of carotene. His work on fermentation and general enzyme chemistry was continued in the Institute established in Stockholm by the Wallenberg and Rockefeller Foundations, special attention being given to the use of enzyme chemistry for the study of heredity and the blood serum.

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 12px; line-height: 15px;">In 1929 von Euler-Chelpin was awarded jointly with Arthur Harden, the Nobel Prize for Chemistry for his work on alcoholic fermentation. In 1914 he had published a book on the chemistry of yeast and alcoholic fermentation. Between 1925 and 1934 he embodied the results of his very extensive research in enzymology in his monograph entitled //Chemie der Enzyme,// which was the first modern monograph on this subject. In 1957 he published with B. Eistert a book on the chemistry and biochemistry of reductones. With C. Martius he had succeeded in preparing triose-reductone. In 1958 he visited Japan and published a monograph on the reductones in collaboration with Professor K. Yamafuji and Drs. Namura and Adachi.

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 12px; line-height: 15px;">Later in 1935 von Euler-Chelpin investigated the biochemistry of tumours and especially studied the nucleic acids in tumours by means of labelled compounds by a technique he invented in collaboration with [|G. de Hevesy]. On tumours he published two important monographs, one entitled the //Biochemistry of Tumours//, written in collaboration with Boleslaw Skarzynski of Cracow and published in 1942 and the other entitled //The Chemotherapy and Prophylaxis of Cancer//, published in 1962.

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 12px; line-height: 15px;">A careful teacher and a friend to all who worked with him, von Euler-Chelpin has inspired and exerted great influence on many workers in the field of biochemistry.

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 12px; line-height: 15px;">He was a Fellow of the Academies of Sciences of Bangalore, Berlin, Munich, Rome, Paris, Vienna, Copenhagen, Helsinki, Moscow, Leningrad, Halle, Göttingen, Tokio and New Delhi. He was a Member of the Royal Swedish Academy of Sciences, the Royal Swedish Academy of Engineering Sciences, the Royal Institution, London, the Finnish Academy of Sciences, and the Academy of Sciences of New Delhi, a Foreign Member of the Max Planck Society, a Corresponding Member of the Academy of Sciences, Paris, and an honorary member of the Academies of Sciences of Helsinki and Japan, the Indian Academy of Sciences, the Chemical Societies of France, Italy and Berlin, and of the Japanese Cancer Association, Tokio. He held honorary doctorates of the Universities of Stockholm, Zurich, Athens, Kiel, Berne, Turin, and Rutgers and New Brunswick Universities. In 1959, he was awarded the Grand Cross for Federal Services with Star, Germany.

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 12px; line-height: 15px;">Von Euler-Chelpin married twice. His first wife, Astrid Cleve, is mentioned above. They had five children. In 1913 he married Elisabeth Baroness af Ugglas, who collaborated with him in his work. There were four children by this marriage.

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 12px; line-height: 15px;">He died in Stockholm on November 6, 1964, at the age of 91.
