It was in the smoky back room of The Eagle, a stone's throw from the Cavendish, that a gray autumn afternoon in 1956 brought together James Watson and Francis Crick face to face with Rosalind Franklin, who had come from Birkbeck. The steam from the mugs fogged the windows, and on the table still lay a cardboard cutout forgotten three years earlier. They knew each other through crystallographers, through a photo passed around without permission, through a rivalry that no one dared name. Franklin had not come to congratulate: she had come to understand, and to demand an accounting.
—Jim, when Maurice showed you my photo number 51 without my consent — what did you see that I did not?
Rosalind, I'll be frank, since I'm speaking to you and not to a committee. What I saw was a cross of black spots, clear, almost insolent — the signature of a helix, we had been taught. In seconds, my heart raced: your B form, hydrated, shouted its structure to anyone who could read. You refused to conclude until you had measured every reflection, and you were right in rigor. But Francis and I were model builders, not measurers. I took your image as permission to guess. I know what that word 'permission' does to you, and I do not wash my hands of it.
I took your image as permission to guess.
—You speak of guessing. But how does one go from a photo to that idea of precise base pairing?
There, Francis should answer you, but let me begin. For weeks I had paired like bases together — adenine against adenine — and nothing held, bulges deformed the helix. One February morning, I had cut out cardboard shapes of each base, and I pushed them on my table like pieces of a child's puzzle. Suddenly adenine and thymine fit exactly like guanine and cytosine — same dimensions, two interchangeable pairs. Erwin Chargaff had counted his As equal to his Ts without knowing why; the cardboard showed the why. Francis looked up from his calculations and immediately saw that this required two complementary strands.
The cardboard showed the why that Chargaff's numbers only noted.
—You theorists built metal models while we at King's diffracted real fibers. Isn't that a bit convenient?
Convenient, perhaps; sufficient, never — I, Francis, concede that. Our model of rods and plates was only a hypothesis in balance until it agreed with data like yours. But a model has a virtue: it does not lie about geometry. If a bond angle is impossible, the metal resists, the skeleton refuses to close. We turned those rods for whole afternoons, checking every interatomic distance with a slide rule. You see, your photograph and our metal were not in competition: your shadow said 'helix', our metal said 'here is how, and no other way'. One without the other would have proved nothing.
—They say that on the evening of your discovery, right here at The Eagle, Francis announced something aloud that made the drinkers turn around. Really?
Really, and I'm still a bit ashamed of it before you, who weigh your words. On February 28, 1953, Francis entered this room and declared to everyone that we had just found the secret of life. The regulars barely looked up from their beer! The landlord, however, noted the date in his register — he still keeps it. At the moment, it was exhilaration, not arrogance: we had just understood how heredity could copy itself. But I confess that saying 'the secret of life' over a mug, while you patiently measured in London, sums up the injustice of our temperaments quite well.
It was exhilaration, not arrogance — we had just understood how heredity copies itself.
—You were so young. Jim, you were twenty-five, and Francis, you didn't even have your doctorate yet. Where did such audacity come from?
From recklessness, largely. At twenty-five, I didn't yet know all that one cannot do — that's a huge advantage. Francis was twelve years older than me and still hadn't defended his thesis, making him the oldest student at the Cavendish and the freest in his opinions. We had neither reputation to protect nor laboratory to direct, only time to talk, talk endlessly. Established researchers dared not guess; we had nothing to lose by being wrong. You, Rosalind, bore the weight of being taken seriously in a milieu that denied it to you. Our audacity was also the privilege of those who are not watched.

—Let's speak plainly. At King's, my data circulated without my being consulted, and Maurice shared it as his own. Did you feel entitled to use it?
No, and I will not dodge. The report from winter 1952, the one containing your measurements of the B form, reached us through lab channels, not from you. At the time, I told myself that science belonged to everyone, that those numbers wanted to be used. That's a nice phrase to cover a breach of courtesy. The truth is, no one asked your opinion, and your falling out with Maurice made it too easy. If our model stands, part of its foundations is made of your work, obtained without your consent. I'd rather tell you to your face than leave it to be said after us.
Part of the foundations of our model is made of your work, obtained without your consent.
—Francis, you don't stop at structure. You now speak of a one-way flow of information in the cell. Where are you going with this?
You put your finger on what occupies me day and night, Rosalind. The double helix only explains storage and copying; the question remains: how does this information become a protein? I believe — and I still argue it with diagrams — that information flows in one direction: from DNA to an intermediate form, RNA, then to proteins, never back. I even imagine small adapter molecules that would translate the language of bases into the language of amino acids. None of this is proven, I grant you, it's a theoretical framework. But if it holds, then all the chemistry of life organizes around a single rule of flow. That is what now keeps me awake.
—And if this principle were verified, how far do you claim to read a living being? The entirety of its heredity, truly?
You touch on my most unreasonable dream, so I'll confide it without shouting in this pub. If information resides in a sequence of bases, then an entire organism is, in a sense, just a very long text written in four letters. Reading that text from end to end would be colossal — we don't even have the tools, and it may take decades. But the principle is there: what makes a man could one day be spelled out. I will likely not see this work completed, and you perhaps neither. Still, the modest geometry we assembled here opens a door that no one can close again.
—Jim, you like to tell stories. When the history of this discovery is written, what place will you give to the woman sitting across from you?
That's the question I dreaded, and you're right to ask me eye to eye. I know I have a quick pen and a convenient memory; I will be tempted to paint myself as a brilliant young man stumbling upon the truth. If I ever tell this story, I risk reducing you to an austere silhouette, the lady who guarded her photos — and that would be a lie out of laziness. The truth I must write, if I have the courage, is that without your B form we would still be groping. Promise to correct me if I ever stray; a story is only honest if those who lived it can contradict it.
I will be tempted to paint myself as a brilliant young man — that would be a lie out of laziness.
—One last thing. The day this discovery is covered with honors, do you think a woman from my lab will have her share?
I would like to answer yes without hesitation, and I cannot honestly. Honors, in our world, follow names that speak loudly and sign short papers — and we signed. You measured in the shadows, in a lab that made no room for you. I fear that memory will first remember the two chatterboxes from the Cavendish. But I tell you this, and Francis thinks so too: no photo was more decisive than yours. If justice exists in science, it will be measured by how we remember what we owe you. On this point, I do not have a clear conscience, and it is good that you came to trouble it.
No photo was more decisive than yours.
