Abstract

It is now twenty years since James Watson published his personal account of the discovery of the structure of DNA and triggered the growing scholarly study of the roots of molecular biology. Watson himself was not concerned with the study of nucleic acids before he became directly involved but at least three detailed histories of the early development of molecular biology have subsequently appeared, together with books, papers and reviews from others who took part, or their partisan representatives. Of these three histories, only one does justice to Avery's work. His surviving DNA collaborator, MacLyn McCarty, believes that only Olby inThe Path to the Double Helixdeals adequately with Avery's contribution.
