The “canonical” story how Rosalind Franklin got wronged by Watson and Crick inadvertently makes her look far less scientifically competent than she was (“She did not realize the significance of her own data!”). This article offers a much more nuanced account of what happened.
What Rosalind Franklin truly contributed to the discovery of DNA’s structure
Franklin was no victim in how the DNA double helix was solved. An overlooked letter and an unpublished news article, both written in 1953, reveal that she was an equal player.
