  • Crystal Vision Dorothy Hodgkin & the Nobel Prize “Few Were Her Equal in Generosity of Spirit, Breadth of Mind, Cultivated Humaneness, Or Gift for Giving
    Crystal Vision Dorothy Hodgkin & the Nobel Prize “Few were her equal in generosity of spirit, breadth of mind, cultivated humaneness, or gift for giving. She should be remembered not only for a lifetime’s succession of brilliantly achieved structures. While those who knew her, experienced her quiet and modest and extremely powerful influence, learned from her more than the positioning of atoms in the three-dimensional molecule, she will be remembered not only with respect, and reverence, and gratitude, but more than anything else, with love. Let that be her lasting memorial.” Anne Sayre, in the Autumn 1995 Newsletter of the American Crystallographic Association Cover image © Emilio Segre Visual Archives/American Institute of Physics/Science Photo Library Letter from the Principal Dr Alice Prochaska, Somerville College Many remarkable woman scientists have passed through Somerville, but few rival Dorothy Hodgkin, whose path-breaking work in crystallography showed a mind not only attuned to high science but one also able to envision a crystal structure from the pattern made by its X-ray diffraction. Her ability to ‘see’ molecules such as cholesterol, penicillin, vitamin B and insulin transformed her field. 2014 sees the fiftieth anniversary of Professor Hodgkin’s Nobel prize. It is also the International Year of Crystallography, marking the 100th anniversary of Max von Laue’s Nobel Prize for Physics, awarded for his discovery that X-rays could be diffracted by crystals. That discovery underpinned Dorothy Hodgkin’s work. We are proud that Somerville supported her at a time when there was widespread opposition to married women pursuing academic careers.

  • Robert Burns Woodward
    The Life and Achievements of Robert Burns Woodward Long Literature Seminar July 13, 2009 Erika A. Crane “The structure known, but not yet accessible by synthesis, is to the chemist what the unclimbed mountain, the uncharted sea, the untilled field, the unreached planet, are to other men. The achievement of the objective in itself cannot but thrill all chemists, who even before they know the details of the journey can apprehend from their own experience the joys and elations, the disappointments and false hopes, the obstacles overcome, the frustrations subdued, which they experienced who traversed a road to the goal. The unique challenge which chemical synthesis provides for the creative imagination and the skilled hand ensures that it will endure as long as men write books, paint pictures, and fashion things which are beautiful, or practical, or both.” “Art and Science in the Synthesis of Organic Compounds: Retrospect and Prospect,” in Pointers and Pathways in Research (Bombay:CIBA of India, 1963).

  • JOHN DESMOND BERNAL – the SAGE by William Reville, University College, Cork
    JOHN DESMOND BERNAL – THE SAGE By William Reville, University College, Cork. I remember excitedly buying a boxed set of 4 books, Science in History by John D. Bernal (Pelican, 1965), when I was an undergraduate. At the time I was an amateur Marxist and Bernal’s work was an encyclopaedic analysis of science and society from a Marxist point of view. I was delighted to learn that Bernal was an Irishman who had spent a brilliant career at the leading edge of UK science, making many notable contributions. John Desmond Bernal was born in Nenagh, Co. Tipperary in 1901. The Bernals were originally Sephardic Jews who came to Ireland in 1840 from Spain via Amsterdam and London. They converted to Catholicism and John was Jesuit-educated. John enthusiastically supported the Easter Rising and, as a boy, he organised a Society for Perpetual Adoration. He moved away from religion as an adult, becoming an atheist. Bernal showed precocious talent right from the start. At the age of two he was taken by his American mother to see his grandmother in California and he amazed passengers on the steamship by talking in both English and French. In later life at Cambridge his fellow students nicknamed him ‘Sage’ because of his great knowledge. Bernal started as a science undergraduate at Cambridge in 1919 where his studies included mineralogy and the mathematics of symmetry. He gained a research position in 1923 at the Royal Institution in London with William Henry Bragg the eminent crystallographer (one who studies crystalline structures using X-rays). He returned to Cambridge in 1927 as the first lecturer in structural crystallography, fully convinced of the enormous potential of his chosen field to elucidate the structure of the technological and biological worlds.
