Walter Fiers is a Belgian molecular biologist. He obtained a degree of Engineer for Chemistry and Agricultural Industries at the University of Ghent in 1954, and started his research career as an enzymologist in the laboratory of Laurent Vandendriessche in Ghent. In 1956-57, he worked with Heinz Holter in Copenhagen. In 1960, he obtained a fellowship from the Rockefeller Foundation and joined the group of Bob Sinsheimer as a postdoc. At the California Institute of Technology Walter Fiers was exposed to Molecular Biology, which was then just developing, studying viral DNA. He demonstrated the physical, covalently closed circularity of Bacteriophage PhiX-174 DNA. In 1962, Fiers moved to Madison, Wisconsin, to work in the laboratory of future Nobel laureate, Gobind Khorana. At the end of 1962, Fiers returned to Belgium and set up the Laboratory of Molecular Biology at the University of Ghent. His research involved Bacteriophage MS2; he was the first to establish the complete nucleotide sequence of a gene and of a viral genome. In 1978 Fiers and his team were the first to reveal the complete nucleotide-sequence of SV40.
