Rosalind Franklin doodle

Today’s Google Doodle honors Rosalind Franklin, whose work on X-ray diffraction was instrumental in determining the double helix structure of DNA. In the Doodle she’s staring at an X-ray diffraction image, known as Photo 51, that got the ball rolling. If you’d like to learn more about how the structure of DNA was determined, Nova has a great interactive dissection of Photo 51 that helps unravel the double helix structure from what looks like just an “X.”

After her work on DNA, she “conducted pioneering work into the structure of viruses.” Sadly, she died due to complications of ovarian cancer in 1958–four years before the Nobel Prize was awarded to Watson and Crick for their research on nucleic acids, and at the time much of her contribution was overlooked.

I can’t help but wonder what else she would have accomplished had she not passed away.
