To the untrained eye Rosalind Franklin's Photo 51 was simply a grainy black-and-white image of dark marks scattered in a rough X shape. But to the eye of a trained scientist it was a clear portrait of a DNA fiber taken with X-rays. And to young scientists James Watson and Francis Crick it helped answer a great mystery - how do organisms live grow develop and survive generation after generation This simple picture would change the way scientists viewed life itself.
Danielle Smith-Llera grew up in coastal Virginia, hearing unforgettable tales about her Mexican and Irish ancestors. She first moved overseas to teach in international schools in Hungary and Brazil. Life in the U.S. Foreign Service has taken her around the world to live in India, Jamaica, Romania, Belgium, the United Kingdom, and Washington, DC. She loves sharing stories--fiction, nonfiction, and a mixture of both--in classrooms, museum exhibits, and, of course, books.
