Rosalind Franklin -- Her Role in the Discovery of DNA

In 1962 Francis Crick, James Watson and Maurice Wilkins were awarded the Nobel Prize for their pioneering work on the structure of DNA. At the time there was little mention of a molecular biologist and crystallographer whose work provided some of the key evidence for their discovery -- Rosalind Franklin. Since then there has been much debate about Rosalind's role in biology's greatest 20th centure discovery and whether she had been unfairly left out of history. Martha Kearney is joined by Deborah Gearing whose play Rosalind: A Question of Life is on at the Birmingham Repertory Theatre this week, and Brenda Maddox author of The Dark Lady of DNA to discuss Rosalind's life and her contribution to science.
