It is especially well known for its degree programs in film, law, music, public administration, physical therapy, business, engineering, and social work. Famous Foreign Biologists and their Significant Contributions. For a number of years Nick Gschwind, a Ph. This work earned me in the same year the Plantamour-Prévost prize of the University of Geneva. It is virtually impossible to list them all in this context, but my warmest collective thanks go to all of them. This may be the reason why I received offers to spend additional postdoctoral time in several excellent laboratories. This is why the first electron micrographs of phage lambda were made in Geneva. Educated in the Swiss public school system, he entered the Federal Institute of Technology in … He studied Natural Sciences at the Swiss Polytechnical School in Zurich from 1949 to 1953. There, he had been converted to a biologist under the influence of Max Delbrück and had chosen to study bacteriophage lambda. For this reason my father received the Nobel Prize for the discovery of the servant with the scissors”. From 1965 to 1970 he was able to procure financial help from the ‘Swiss National Science Foundation’ to carry out fundamental research. In 1961 Arber and another geneticist, Daisy Dussoix, reported this phenomenon to the scientific community for the first time during the ‘First International Biophysics Congress’ which was held in Stockholm. Shared the 1978 Nobel Prize in Physiology or Medicine with Werner Arber and Daniel Nathans for the discovery of restriction endonucleases, which led to the development of recombinant DNA technology. Additional contributions to this goal come from contacts with other nearby University Institutes as well as with the private research Institutions in the city. Werner Arber Biozentrum, University of Basel, Klingelbergstrasse 50-70, CH-4056 Basel, Switzerland By comparing strategies of genetic alterations introduced in genetic engineering with spontaneously occurring genetic variation, we have come to conclude that both processes depend on several distinct and specific molecular mechanisms. While doing this job he grew familiar with the fundamental aspects of genetics and ‘bacteriophage physiology’ and became interested in a totally new field of research on ‘bacteriophage’. Shared the 1978 Nobel Prize in Physiology or Medicine with Hamilton Smith and Daniel Nathans for the discovery of restriction endonucleases, which led to the development of recombinant DNA technology. After explaining her in simple terms the basic concepts of the mechanisms of restriction enzymes, she, after some reflection, reexpressed this message in her own terms by a tale, which in the meantime has found wide diffusion around the world. It is in the last year of this study that I made my first contacts with fundamental research, when working on the isolation and characterisation of a new isomer of Cl34, with a halflife of 1.5 seconds. I see two ways to reach this goal. He used his Nobel Prize money to invite his friends for this walk. Werner Arber's 170 research works with 7,182 citations and 10,774 reads, including: Genetic engineering represents a safe approach for innovations improving nutritional contents of major food crops Before returning to Geneva at the beginning of 1960, he spent a few weeks working at the ‘Gunther Stent’ laboratory in Berkeley, the ‘Joshua Lederberg’ laboratory in Stanford and the ‘Salvador Luria’ laboratory at the ‘Massachusetts Institute of Technology’ in Cambridge. When I started investigations on the mechanisms of host-controlled modification, I did not of course imagine that this sidetrack would keep my interest for many years. She did her PhD with Swiss scientist Werner Arber and in the process discovered restriction enzymes, proteins that can cut DNA at precise points. In 1981 he became a member of the ‘World Knowledge Dialogue Scientific Board’ and also a member of the ‘Pontifical Academy of Sciences’. Their work would lead t And so was the DNA from unirradiated phage lambda used to measure adsorption and DNA injection into restrictive bacterial strains! After my Ph. In January 2011 he was made the president of the ‘Pontifical Academy of Sciences’ by Pope Benedict XVI. Famous Foreign Biologists and their Significant Contributions. If a foreign king invades a bacterium, this servant can cut him in small fragments, but he does not do any harm to his own king. American microbiologist. Tasked with a mission to manage Alfred Nobel's fortune and has ultimate responsibility for fulfilling the intentions of Nobel's will. At the same time, Grete Kellenberger had looked at the fate of DNA from irradiated phage lambda upon infection of host bacteria: part of it was rapidly degraded after injection into the host. Prix Nobel/ Nobel Lectures/The Nobel Prizes. Werner Arber was born in Gränichen, Switzerland, on June 3, 1929. On the other hand, I had remained in close contact with Eduard Kellenberger, and he urged me to come back to Geneva in order to lead an investigation on radiation effects on microorganisms. Within about one year of study, it had become clear that strain-specific restriction and modification directly affected the DNA, without however causing mutations. It is in the last year of this study that I made my first contacts with fundamental research, when working on the isolation and characterisation of a new isomer of Cl, The Nobel Prize in Physiology or Medicine 1978, Werner Arber - Nobel Lecture: Promotion and Limitation of Genetic Exchange. University of Southern California, private coeducational institution of higher education in Los Angeles, California. NobelPrize.org. The first step to accomplish this was easy thanks to a hint received from Esther Lederberg to look for cotransduction of the Ma1+ and lambdaS characters. Twelve laureates were awarded a Nobel Prize in 2020, for achievements that have conferred the greatest benefit to humankind. From 1949 to 1953 I studied towards the diploma in Natural Sciences at the Swiss Polytechnical School in Zurich. Werner Arber, Daniel Nathans, and Hamilton O. Smith received the Nobel Prize in 1978 for working out the mechanism of restriction enzymes (see Restriction, Modification, and Epigenetics). Nobel laureate Prof. Werner Arber visited Amity University and delivered an informative lecture outlining his sojourn into the mysteries of fundamental research which started 60 years ago. When Silvia learned that I had been honored by the Nobelprize she not only wanted to know what this is, but also why I was chosen as a Laureate. D student, and John Smith, working for various lengths of time with us, succeeded in careful in vivo and in vitro measurements on methylation to validate and extend the earlier conclusions. These can be grouped into three strategies with different qualities with regard to their contributions to biological evolution. His scientific contributions and editing acumen have been appreciated by seven Nobel Laureates including Profs. In November 1953 he took up the job of an assistant for electron microscopy at the ‘Biophysics Laboratory’ at the ‘University of Geneva’. Werner Arber (2014) ... classify these mechanisms into three natural strategies of genetic variation according to specific qualities of their contributions to biological evolution: local DNA sequence changes, intragenomic rearrangements of DNA segments, and the acquisition of a segment of foreign DNA by horizontal gene transfer. Since my coming to Basel, I devoted relatively little of my time to further studies on restriction and modification mechanisms. Since this research largely makes use of restriction enzymes, although it in no way fully depends on them, I consider it a personal obligation to contribute to the best of my abilities to the solution of questions which arose in the scientific and public debate on this research in the last few years. Daisy Roulland-Dussoix was a Swiss microbial geneticist. Shared the 1978 Nobel Prize in Physiology or Medicine with Werner Arber and Daniel Nathans for the discovery of restriction endonucleases, which led to the development of recombinant DNA technology. He received many offers from various laboratories for post-doctoral work as his doctoral thesis was highly appreciated by the genetics fraternity. Werner Arber received the ‘Plantamour-Prevost’ prize from the ‘University of Geneva’ in 1962. From 1949 to 1953 I studied towards the diploma in Natural Sciences at the Swiss Polytechnical School in Zurich. I started my new appointment at the University of Basel in October 1971 after having spent one year as a visiting Miller Research Professor at the Department of Molecular Biology of the University of California in Berkeley. Werner Arber is a Swiss microbiologist and a geneticist who was awarded the Nobel Prize in Physiology or Medicine for his work on the discovery of the process by which enzymes could be used to break down the DNA molecules into smaller fragments without losing … I consider our insights into the natural laws of biological evolution as one of my contributions … at the time of the award and later published in the book series Les While working as a research associate with Bertani, I received P1 at first hand which enabled me to study phage Pl-mediated transduction of monomeric and dimeric lambda prophage genomes as well as of the fertility plasmid F. In the meantime, my Ph. He next joined the gymnasium at the ‘Kantonsschule Aarau’ from where he received a B-type maturity in 1949. This work would not have been possible without a very fruitful help by a large number of collaborators in my own laboratory and of colleagues working on related topics in their own laboratories. Werner Arber and Hamilton Smith both participated in the CSHL meeting. It was already known that bacteria could break down viruses called phages. Very rapidly I realized that this was due to host-controlled modification, a phenomenon described for lambda and E. coli strains seven years earlier by Joe Bertani and Jean Weigle. Another significant contribution to the process of humulin production was by Werner Arber, Hamilton O. Smith, and Daniel Nathans in the late 1960s and early 1970s, as they were responsible for discovering the restriction enzymes. This model, which was published in 1953, was incorrect, but it did lay the foundation for James Watson and Francis Crick's correct model of DNA as a double helix. It might thus be justified to finish this curriculum vitae by its reproduction: When I come to the laboratory of my father, I usually see some plates lying on the tables. One of the first experiments after my return to Geneva was to render E. coli B and its radiation resistant strain B/r sensitive to phage lambda. Restriction enzyme is an enzyme that … Discover Your Abilities and Aspirations! Shared the 1978 Nobel Prize in Physiology or Medicine with Werner Arber and Daniel Nathans for the discovery of restriction endonucleases, which led to the development of recombinant DNA technology. During the last part of his studies he first became interested in fundamental research while trying to isolate an isomer and study its characteristics. Stimulated by Jean Weigle we soon turned our interests also to other properties of lambda, and the study of defective lambda prophage mutants became the topic of my doctoral thesis. Because of their independence on extended nucleotide homologies these forces bring about exchange of largely unrelated genetic materials. Look for popular awards and laureates in different fields, and discover the history of the Nobel Prize. In 1953 he started his postgraduate work as an electron microscopist at the Biophysics Laboratory of the University of Geneva, mainly working with microorganisms. 18 Jan 2021. This might have been related to a more general lack of public interest for this field, which was perhaps due to the economic structure of the city of Geneva and its environments. Werner Arber (born 3 June 1929) is a Swiss microbiologist and geneticist. We could indeed show that lambda-mediated transduction is based on the formation of substitution mutants, which had replaced a part of the phage genes by genes from the bacterial chromosome. He also made other important contributions to science policy. Solid notions on naturally occurring genetic exchange between organisms that are not directly related will also form a good basis for a scientific evaluation of conjectural risks of in vitro recombinant DNA research. In 1964 Bill Wood laid out a solid basis for the genetics of the restiction and modification systems EcoK and EcoB. His work was centered mainly on the protective nature of some of the enzymes in the bacteria that prevent the growth of the ‘bacteriophages’. In spite of spending many hours to keep the microscope “Arthur” in reasonable working condition, I had enough time not only to help developing preparation techniques for biological specimens in view of their observation in the electron microscope, but also to become familiar with fundamental questions of bacteriophage physiology and genetics, which at that time was still a relatively new and unknown field. This web page shows only a small excerpt of our Arber research. But general knowledge on this to my mind extremely important field is still very scarce and deserves continued attention. Werner Arber and some more scientists had already started work on the findings of another Nobel laureate named Salvador Luria during the late 1950s and early 1960s. In the story the DNA has been named as the King ruling over a kingdom of subjects who are the bacteria. Werner Arber (born 3 June 1929 in Gränichen, Aargau) is a Swiss microbiologist and geneticist. ... Werner Arber. In response to their interest and understanding for my scientific activities, I have tried to give them my personal affection needed for a harmonious life. Read more >> William Smith (1769-1839). These findings were reported by myself and Daisy Dussoix for the first time to the scientific community during the First International Biophysics Congress held in Stockholm in the summer of 1961. The king is like a book, in which everything is noted on the work to be done by the servants. Greek philosopher and early scientist. After having suffered a heart attack, he had left Geneva to become a researcher at the Department of Biology of the California Institute of Technology in Pasadena. Our two daughters Silvia and Caroline were born in 1968 and in 1974, respectively. Werner Arber's 170 research works with 7,182 citations and 10,774 reads, including: Genetic engineering represents a safe approach for innovations improving nutritional contents of major food crops He shared the prize with two other American scientists named Daniel Nathans and Hamilton Othanel Smith who collaborated with him in the experiments. Otherwise I might not have felt justified to engage in this work because of its lack of direct relevance to radiation research. Their experiments also brought important conclusions with regard to the concept of the sites of recognition on the DNA for the restriction and modification enzymes. (Nobel.org)-What do you think is your main contribution to science? The first is scientific and tends as just stated to better understand what nature does in its nonhomologous genetic exchange. As a compromise, I decided to return to Geneva at the beginning of 1960, but only after having spent several very fruitful weeks at each of the laboratories of Gunther Stent in Berkeley, Joshua Lederberg in Stanford and Salvador Luria at the Massachusetts Institute of Technology, Cambridge. This diversity within the same house largely contributes to fruitful collaborative projects and it helps to keep horizons broad both in research and teaching. With the resulting little pieces it is much easier to investigate the secrets. He was also inspired by the lectures given by Jean Weigle who had been a professor of experimental physics at the ‘University of Geneva’. by the Laureate. In 1963 he spent one year at the ‘Department of Molecular Biology’ under the ‘University of California, Berkeley’ as a visiting ‘Miller Research Professor’. Biological evolution … I am fortunate to have found a continued support and steady encouragement by my family, in particular by my parents, and, since we became married in 1966, by my wife Antonia. Research Interests. Prof. em. For us human beings these instructions of the king are a mystery. The Nobel Prizes 1978, Editor Wilhelm Odelberg, [Nobel Foundation], Stockholm, 1979. Werner Arber (1929-). These colonies remind me of a city with many inhabitants. . ... Werner Arber. Hamilton O. Smith, American microbiologist who shared, with Werner Arber and Daniel Nathans, the 1978 Nobel Prize for Physiology or Medicine for his discovery of a new class of restriction enzymes that recognize specific sequences of nucleotides in a molecule of DNA … Within a year of research he was able to establish the fact that DNA of both the ‘bacteriophage’ and the cell had been affected by modification and strain-specific restrictions. Our postdoctoral workers Katsutoshi Mise, Shigeru Iida and Jürg Meyer brought important contributions to the understanding of these phenomena, mainly by the use of the bacteriophage P1 genome as a natural vector of transposable elements. Werner Arber is a Swiss microbiologist and a geneticist who was awarded the Nobel Prize in Physiology or Medicine for his work on the discovery of the process by which enzymes could be used to break down the DNA molecules into smaller fragments without losing their inherent characteristics and could then be studied easily. Nobel Media AB 2021. From Les Prix Nobel. Research Interests. Another family is formed by restriction and modification systems EcoP1 and EcoP15. To cite this section These are thick and short, almost like balls. WERNER ARBER Summary Applications of scientific knowledge often refer to technological uses, but their impact on our world view can also be of great importance. As an illustration that my work has not always been easy and accompanied by success, I would like to refer to my long, fruitless and thus largely unpublished attempts to find experimental evidence for the diversification of restriction and modification systems in the course of evolution. Arber was studying an earlier known phenomenon, “host controlled restriction of bacteriophages”, and found that this … That the basic idea for this search was good was recently shown by Len Bullas, Charles Colson and Aline van Pel (J. Gen. Microbiol. I was born on June 3rd, 1929 in Gränichen in the Canton of Aargau, Switzerland, where I went to the public schools until the age of 16. Along with American researchers Hamilton Smith and Daniel Nathans, Werner Arber shared the 1978 Nobel Prize in Physiology or Medicine for the discovery of restriction endonucleases. This was when direct financial help was not available from the Swiss federal government. At a time before the Swiss Universities received direct financial help from the federal government, the Swiss National Science Foundation awarded “personal grants” to qualified researchers to allow them to guide projects of fundamental research at a Swiss University. He received an offer from the ‘University of Southern California’ in Los Angeles in the summer of 1958 after completing his PhD to work with Joe Bertani who had collaborated earlier with Jean Weigle in the research on ‘bacteriophages’. Arber started to work with Joe Bertani on a ‘bacteriophage’ of the E. Coli virus which Bertani had isolated a few years earlier. It soon also became obvious that restriction and modification were properties of the bacterial strains and acted not only on infecting bacteriophage DNA, but also on cellular DNA as manifested in conjugation experiments. While doing this he became familiar with the basic issues related to genetics and the physiology of ‘bacteriophages’. MLA style: Werner Arber – Biographical. This phenomenon became the topic of Daisy Dussoix’s doctoral thesis, who very carefully not only studied the DNA degradation of phage that was not properly modified, but who also tried to detect parallels between the fate of unmodified DNA in restrictive conditions and of irradiated DNA in normal host cells. My first contribution to our journal club concerned Watson and Crick’s papers on the structure of DNA. These years were devoted to hard work to consolidate the preliminary data and the concepts resulting from them, and to extend the acquired notions, in particular with regard to the mechanisms of modification by nucleotide methylation, with regard to the genetic control of restriction and modification and with regard to the enzymology and molecular mechanisms of these reactions. This autobiography/biography was written My research interests focus on mechanisms to promote and to inhibit the exchange of genetic information between microorganisms: DNA restriction and modification systems; genetic recombination mechanisms, including transposition and site-specific inversion and their relevance for genetic rearrangements; and spontaneous mutagenesis and microbial evolution. Werner Arber was born in Gränichen, Switzerland, on June 3, 1929. He studied at the public schools in Granichen until he was 16. Early History of the Arber family. Werner Arber Werner Arber was born on June 3, 1929, in Granichen, Switzerland. Werner Arber started this field of research in Geneva during the 1960’s. He is very long, but skinny. Werner Arber is a Swiss microbiologist and geneticist who together with Daisy Dussoix helped discover and understand the mechanism of restriction enzymes, laying the foundation for their adoption as molecular scissors. D. thesis on lambda-gal, although written in French, had been read, or, what is perhaps more essential, understood in its conclusions by many leading microbial geneticists. At the end of the 1950’s, a special credit had been voted for by the Swiss Parliament for research in atomic energy, including radiation effects on living organisms. He discovered restriction enzymes. Restriction enzyme is an enzyme that … He discussed with them science and other matters in life. Werner Arber. Eduard Kellenberger felt that important contributions to the latter questions could be expected from studies with microorganisms, and he had therefore submitted a research proposal which found approval by the granting agency, the Swiss National Science Foundation. The second is rather political and it consists in actions to stimulate continued awareness of responsibility to work with a maximum of care in all scientific investigations, which should, however, be allowed to be done under optimal academic freedom. This view is here exemplified with recent developments in … These, at that time perhaps more subconscious concerns, might have helped me to accept in 1968 an offer for a professorship at the University of Basel, since I felt that more general interest would be given to molecular genetics in this city with a long tradition of biomedical research at its industries. In 1962 Arber presented the findings more elaborately to the ‘Science Faculty’ at the ‘University of Geneva’ for which he was awarded by the university. Several years before, Bertani had isolated and characterised another bacteriophage of E. coli, P1. A curriculum vitae would be incomplete without reference to my private life. American microbiologist. It was already known that bacteria could break down viruses called phages. Werner Arber, Swiss microbiologist who was a corecipient of the 1978 Nobel Prize for Physiology or Medicine for his work in molecular genetics, specifically the discovery and application of enzymes that break the giant molecules of DNA into manageable pieces. These topics had already engaged the attention of Jean Weigle and Grete Kellenberger for a number of years. In fact, one of the at first sight rather frustrating observation was that lysates of lambda-gal, which indeed could still cause the infected host cell to lyse as does wild type phage lambda, did not contain any structural components of lambda (phage particles, heads or tails) discernible in the electron microscope. This made him the first Protestant to hold the post of president in an otherwise Catholic institution. When Werner Arber’s daughter Silvia heard of his discovery after he got the Nobel Prize she made a story out of the discovery which received wide publicity. In 1965 I was promoted extraordinary professor for molecular genetics at the University of Geneva. Werner Arber (born 3 June 1929 in Gränichen, Aargau) is a Swiss microbiologist and geneticist. In the summer of 1956, we learned about experiments made by Larry Morse and Esther and Joshua Lederberg on the lambda-mediated transduction (gene transfer from one bacterial strain to another by a bacteriophage serving as vector) of bacterial determinants for galactose fermentation. To do so, they collect many servants with scissors and put them onto a king, so that the king is cut into pieces. This was the end of my career as an electron microscopist and in chosing genetic and physiological approaches I became a molecular geneticist. Several outreach organisations and activities have been developed to inspire generations and disseminate knowledge about the Nobel Prize. They have two daughters, Silvia and Caroline, who were born in 1968 and 1974 respectively. My father has discovered a servant who serves as a pair of scissors. The opportunity made Arber give up his job involving electron microscopy and change over to research in genetics which became a passion with him over the years. Learn more about Arber’s life and work. In 1968 he received an offer of professorship at the ‘University of Basel’. Very rapidly, thanks to the stimulating help by Jean Weigle and Grete Kellenberger, this turned out to be extremely fruitful. Not that I have lost my interest in them. Their work would lead to the development of recombinant DNA technology. In 1978, he won the Nobel price in medicines and physiology. The Nobel Prize in Physiology or Medicine 1978 was awarded jointly to Werner Arber, Daniel Nathans and Hamilton O. Smith "for the discovery of restriction enzymes and their application to problems of molecular genetics".
