Prof. Werner Arber

Werner Arber (born 3 June 1929, Gränichen, Aargau) is a Swiss microbiologist and geneticist. 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. Their work would lead to the development of recombinant DNA technology.
Arber studied chemistry and physics at the Swiss Federal Institute of Technology in Zürich from 1949 to 1953. Late in 1953 he took an assistantship for electron microscopy at the University of Geneva, in time left the electron microscope, went on to research bacteriophages and write his dissertation on defective lambda prophage mutants. In his Nobel Autobiography, he writes:
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. Since these investigators had encountered defective lysogenic strains among their transductants, we felt that such strains should be included in the collection of lambda prophage mutants under study in our laboratory. Very rapidly, thanks to the stimulating help by Jean Weigle and Grete Kellenberger, this turned out to be extremely fruitful. [...] This was the end of my career as an electron microscopist and in chosing genetic and physiological approaches I became a molecular geneticist.
He received his doctorate in 1958 from the University of Geneva.
Arber then worked at the University of Southern California in phage genetics with Gio ("Joe") Bertani starting in the summer of 1958. Late in 1959 he accepted an offer to return to Geneva at the beginning of 1960, but only after spending "several very fruitful weeks" at each of the laboratories of Gunther Stent (University of California, Berkeley), Joshua Lederberg and Esther Lederberg (Stanford University) and Salvador Luria (Massachusetts Institute of Technology).
Back at the University of Geneva, Arber worked in a laboratory in the basement of the Physics Institute, where he carried out productive research and hosted "a number of first class graduate students, postdoctoral fellows and senior scientists." In 1965 the University of Geneva promoted him to Extraordinary Professor for Molecular Genetics. In 1971, after spending a year as a visiting professor in the Department of Molecular Biology of the University of California in Berkeley, Arber moved to the University of Basel. In Basel, he was one of the first persons to work in the newly-constructed Biozentrum, which housed the departments of biophysics, biochemistry, microbiology, structural biology, cell biology and pharmacology and was thus conducive to interdisciplinary research.
Werner Arber is member of the World Knowledge Dialogue Scientific Board and of the Pontifical Academy of Sciences since 1981. He was elected a Fellow of the American Academy of Arts and Sciences in 1984. Pope Benedict XVI appointed him as President of the Pontifical Academy of Sciences on January 2011, making him the first Protestant to hold the position.
Arber was one of 20 Nobel Laureates who signed the "Stockholm Memorandum" at the 3rd Nobel Laureate Symposium on Global Sustainability in Stockholm, Sweden on 18 May 2011.
Arber is married and has two daughters.
