In February, Profiles in Science, the NLM site celebrating 20th century biomedical research and public health leaders, added an extensive selection from the papers of chemist and crystallographer Rosalind Franklin, PhD, whose groundbreaking work helped uncover the structure of DNA.

“Rosalind Franklin was a gifted experimental scientist who greatly expanded the application of X-ray crystallography to molecular biology. Her X-ray diffraction studies were essential to modeling complex biological molecules such as DNA and virus proteins,” commented NLM Director Donald Lindberg, MD.
