Peter, your being unfair accusing Chargiff of being a squawker. He put Watson and Crick on the right track no matter which way you look at it thanks to the rules he formulated. Without him (and others) they'd never have got that paper out in 1953.
I spoke about this in a short lecture I gave at the Royal Society a few years back and I consider it a great pity that only the key figures involved are household names. The likes of Chargiff, Avery, Gosling and others are rarely acknowledged and I'd recommend a copy of Gareth Williams's book "Unravelling the double helix - the lost heroes of DNA" for an unbiased and intelligent review of the reality of what happened all those years ago.
As for wiki, let's be serious: as long as the online resource remains editable by anyone with access to the Web, you can hardly criticise the veracity or omissions in the articles. They remain the opinion of the writer unless someone else picks up what they consider to be a falsehood and changes the content which can then be changed back ad nauseum.
Ah well, it Christmas so I'll leave there. I too have considerable professional knowledge of the discovery of DNA but this isn't the time nor the place.
