It is time now to introduce my friend Peter Duesberg. Where do I begin? At NIH, Peter is sometimes known as the battling bulldog. He gets his teeth into something and 1 year, 5 years, 10 years, 20 years later those teeth are still sunk in it. [...] He began working with retroviruses around 1966. The next major phase of his work involved his classic studies with Petter Vogt; Vogt the biologist, Peter the biochemist. This really led to the first molecular and genetically defined transforming gene, the sarc gene. A great deal of this brilliant and original, the real critical aspects, was carried out by this extraordinarily effective collaboration through the 1970s.
