Symmetry groups wrapping paper
You may have heard mathematicians say that there are only 17 types of wallpaper. Which is a shorthand way of saying, if you print a repeating pattern, it will definitely have 1 of only 17 possible sym...

Crystallography is notoriously hard, and she was *very* good at it.

Rosalind Franklin. Just leaving her name here because she should have been considered part of the discovery, but she died in part due to radiation exposure (DNA structure was discovered through x-ray crystallography). She collected the primary data. Watson himself admitted it ('The Double Helix')

Watson was an opportunist. He took advantage of Crick’s command of crystallography and managed to get access to Franklin’s experimental data including the famous Photography 51 which reveal a simple cross-like diffraction pattern of DNA in high humidity.

Crick & Watson are usually the folks credited with discovering the double helix of DNA.
Rosalind Franklin did the x-ray crystallography that enabled that work. They stole it from her, and she died of cancer.

Rosalind Franklin was accomplished, built her own x-ray crystallography equipment, had spent WW2 on groundbreaking nanoscopic studies of coal for the War Department
Watson’s memoir admits he saw women as prey (“au pair” he wrote) or “goddess” and “Rosalind was neither; worse, she was angry”

Crick and Watson should have put Franklin as an author on their DNA structure paper in Nature because they only got the structure right by getting to look at her X-ray crystallography data. I believe Wilkins showed them the data without Franklin's approval but I could be wrong.

Exactly. Just came here to say the same thing. Without her painstaking crystallography work and if Wilkins had not filched her photograph Crick & Watson would never have got that far so fast.

This book greatly increased my interest in chemistry and biology and spurred a life-long interest in crystallography. I reread the book several times and starting trying to learn more about several aspects of the work.

I see X-ray crystallography is the topic! Contact me for all your X-ray content. I did a postdoc in X-ray crystallography at Cambridge many years ago.
Although I was stationed in Durham because it was easier to get machine time there.

Only have undergrad in bio but I loved history and yet hadn't heard Florence Bell who was important in the initial preps of DNA for crystallography for Cavendish lab. She got sidelined and no credit (they wouldn't grant her degree from Cambridge in the '30s!)
Heard about her on BBC program

Watson was a terrible racist sexist bigot. He was not a genius. He profited enormously off of x-ray crystallography work on the structure of DNA done by Rosalind Franklin and then didnt give her nearly enough credit for it.
He’s simply totally wrong that ppl with darker skin are less intelligent.

Then she wasn't allowed to share the Nobel Prize because she died of ovarian cancer before it was awarded - if I had to guess, her cancer was probably caused by doing all of the X-ray crystallography work that Crick and Watson's "little paper" rested on almost entirely.

As a former crystallography student, it gives me great pleasure to see Wegmans experimenting with more dense packing layouts for bottled water.
When I was a student, we had a homework assignment about the most efficient packing method for soda cans!

he was far from a genius and he gets no passes. Crick was much more talented and accomplished, as was Rosalind Franklin whose crystallography images they took without permission and without which their “discovery” would have been impossible.

Turns out it was too big and hence a complex mix of crystal forms. Useless for crystallography. Colleague was furious.
He was grumpy for weeks.
Taught me a lesson. If you have anything at all (a crystal) it might be enough. A good crystal might be up to 1mm. More than that, probs forget it.

An expert in x-ray crystallography, Rosalind Franklin led the team that created what has been called "arguably the most important photo ever taken," the celebrated Photo 51, which revealed the helical structure of DNA. #RosalindFranklin #NobelLaureate *at the very least
Thinking only of Rosalind Franklin today, and what was stolen from her (and so many other female scientists alongside her).

A bit more complex. Franklin explicitly refused to work with them because she was trying to solve the same problem. But her PI Maurice Wilkins showed the conclusive crystallography images to Watson (taken by her student Gosling), which she was unable to interpret.

As far as I know he did not literally steal them but heard Franklin lecture about her work and was then shown the crystallography by Maurice Wilkins without Franklin's permission.
