In 1951, Pauling published the structure of the alpha helix, a fundamentally important structural component of proteins. In early 1953, Pauling published a triple helix model of DNA, which subsequently turned out to be incorrect. [3] Both Crick, and particularly Watson, thought that they were racing against Pauling to discover the structure of DNA.

February 15 – Linus Pauling proposes a DNA triple helix structure, [1] which is rapidly shown to be incorrect. 25 April 1953: the DNA double helix is first formally described. February 28 – Francis Crick and James Watson enter The Eagle, Cambridge, for a pub lunch announcing "We have discovered the secret of life." [2]
The Linus Pauling Institute still exists, but moved in 1996 from Palo Alto, California, to Corvallis, Oregon, where it is part of the Linus Pauling Science Center at Oregon State University. [ 181 ] [ 182 ] [ 183 ] The Valley Library Special Collections at Oregon State University contain the Ava Helen and Linus Pauling Papers, including ...
Narrated by Jeff Goldblum, it features Watson, Wilkins, Gosling and Peter Pauling (son of Linus Pauling). [27] A play entitled Photograph 51 by Anna Ziegler focuses on the role of X-ray crystallographer Rosalind Franklin in the discovery of the structure of DNA. [28] [29] This play won the third STAGE International Script Competition in 2008. [30]
It covered the discovery of DNA in 1953. [1] Maurice Wilkins and his involvement with the Manhattan Project, speaking in his university office in London; Linus Pauling's son Peter, of Caltech, now lived in Wales; Linus Pauling approached the discovery of the structure of DNA in a much more methodical rigid manner, perhaps in a plodding way, and Pauling was never one to take the same un-thought ...
Some of these structures were proposed during the 1950s before the structure of the double helix was solved, most famously by Linus Pauling. Non-helical or "side-by-side" models of DNA were proposed in the 1970s to address what appeared at the time to be problems with the topology of circular DNA chromosomes during replication (subsequently ...
Pauling had deduced this structure from X-ray patterns and from attempts to physically model the structures. (Pauling was also later to suggest an incorrect three chain helical DNA structure based on Astbury's data.) Even in the initial diffraction data from DNA by Maurice Wilkins, it was evident that the structure involved helices.
