title: Historical opinion: Erwin Chargaff and his 'rules' for the base composition of DNA: why did he fail to see the possibility of complementarity?
abstract: Erwin Chargaff was one of the more interesting and colourful figures of the historic decade that heralded the proposal of the double helical structure of DNA by Watson and Crick in 1953. In describing Chargaff's important contribution to the study of DNA, particularly its base composition, this article seeks to suggest why, despite his substantial achievements, he failed to anticipate some of the key features of the Watson-Crick model, particularly complementarity between bases--a failure that left him deeply embittered for the rest of his life.
