On what would have been her 93rd birthday, today's Google Doodle honors Rosalind Franklin. Franklin took an X-ray diffraction image of the DNA molecule in 1952. The image was called Photo 51 and was the significant piece to identifying the structure and symphony of DNA.
Today's logo depicts Franklin in the second "O," staring through her X-ray tubes, which stand for the "G" at a double helix, representing the "l." The Google "e" is an image of what DNA looked like.
Franklin was the daughter of an rich British family who attended Newnham College and King's College. Her early areas of research were with coal, detailing its permeability.
It was her work that led to the use of coal as a fuel, as well as a filter for gas masks. Her work with coal was the basis for her theory, earning her a PhD from Cambridge University.
As a research associate at King's College London, Franklin was assigned to work with then-student Raymond Gosling. Her facts of chemistry and X-ray diffraction led to her photograph.
Her research and papers contributed to the understanding of the composition of both the A-DNA and B-DNA molecules as helices.
In later years, three other researches were approved information on Franklin's research. Francis Crick, James Watson and Maurice Wilkins later mapped the double helix. Their work earned them a Nobel Prize in 1962, four years after Franklin died of ovarian cancer.
Although best known for her work on mapping DNA, Franklin also used X-ray crystallography to study the tobacco mosaic virus (TMV) and researched RNA, specially in regards to RNA viruses. While immensely sick and undergoing cancer treatment, Franklin and her research team produced 13 papers in the last two years leading up to her death in 1958.
Posthumously, Franklin has been familiar in a number of ways. King's College in London named a dormitory Rosalind Franklin Hall and an academic building named the Franklin-Wilkins building. The American National Cancer Institute recognized the Rosalind E. Franklin Award for Women in science. In 2004, The Chicago Medical School renamed its Finch University to the Rosalink Franklin University of Medicine and Science.
