    • Women in science. Dispelling the myth Berlin 18th May 2013
    • Pedro Miguel Etxenike The DNA double helix was discovered thanks to the experiments of Rosalind Franklin Lamia Were they few or just unknown ?...
    • Women as a group did not have access to Academies of Science They were denied access to University till Switzerland 1860 UK 1895 Cambridge 1948, Oxford 1921 France 1880 EcolePolytechnique1972 Germany 1900 Spain 1910 Royal Society (Londres 1662) 1945 Academie des Science (París 1666) 1979 AkademiederWissenschaften (Berlín 1700) 1964 Real Academia de Ciencias Exactas, Físicas y Naturales (Madrid 1847) 1988
    • Women’s struggle did not begin in the mid-late XIX century • Margaret Cavendish 1623-1673 • MaryAstell 1666-1731 • Daniel Defoe 1660 –1731 • Olimpia de Gouges 1748-1793 • MaryWollstonecraft 1759-1797 There were individual calls by many people since XV century Real progress began with the first-wave feminism movement THE LANGHAM GROUP •High and equal education for women • Employment opportunities • Suffrage for women • Reform of the law regarding married women
    • • North LondonCollegiateSchool 1850 (Frances Mary Bus) • Cheltenham Ladie’sCollege 1858 (Dorothea Beale) HIGH EDUCATIONWASTHE KEY GIRTON and NEWNHAM: A college like Man Emily Davis: only if women succeeded in subjects held to be prestigious for men would their educational achievements recognize as equally valid. ‘Different’ would automatically mean ‘inferior’. •Girton 1869 (Emily Girton) •Newnham Hall 1875 (Eleanor Sidgwick) •LondonSchoolof Medicine forWomen 1874 (Sophia Jex Blake) Mathematics could not be undertaken by women, brain work energy could be diverted from their reproductive system. Philippa Fawcett in 1890 of Newnham beat the top male student.
    • • University of London 1878 (excluded form studying science) • Oxford 1921 • Cambridge 1948 Full member of Universities till WW I: first graduate women were doctors •Gain access to university studies • Graduate • Practice the profession ? i) Rapid increase of women (general feminization was feared) ii) Objection of men student to the attendance of women iii) Women need a peculiar education (Reason in nature)

    • Conclusion:There were few in every country and time period, but more than are known or thought to have been. Marie Curie (NP,NC) Irene Joliot-Curie (NC) GertyTheresaCori (NM) MariaGopert-Mayer (NP) Dorothy Hodgkin (NC) RosalynYalow (NM) BarbaraMacClintock (NM) Rita Levi.Montacini (NM) Gertrude Elion (NM) Christiane Nusslein-Volhar (NM) LiseMeitner (P) Chien-ShiungWu (P) Rosalind Franklin (C) Jocelyn Bell Burnell (P) Emmy Nöther (M) Mileva Maric (P) Martha Chase (C) Daisy Roulland-Dussoix (C) Esther Lederberg (M) Caroline Herschel (P) Lynn Margulis (M) Women through their participation became the agent of change. ( Bonilla et al. 2005)
    • Lise Meitner and the nuclear fission ▪ 1878 Vienna, in a Jewish family. ▪ During the XIX century women were excluded from Universities by law.The need for medical doctors for Muslim women opened the doors. ▪ In 1901 she starts university and meets Ludwig Boltzmann. ▪ In 1906 she is awarded a Doctor title in Physics, fascinated by research she decides to move to Berlin and continue her career.

    • Lise Meitner: Fission ▪ In 1938 she escapes from Germany ▪ Otto Fritz Strassmann ▪ In 1939 she discovers the nuclear fission ▪ In 1942 refuses to participate in the Manhattan Project ▪ 1944 Otto Hahn receives the Nobel Prize in Chemistry
    • LiseMeitner: Womanoftheyear ▪ In 1946 she receives the honour of "Woman of theYear" ▪ In 1947 she receives the Award of the City ofVienna for science ▪ In 1949 Max Planck Medal ▪ In 1950 Otto HahnAward ▪ In 1960 WilhemExner Medal ▪ In 1966 Enrico Fermi Award ▪ The element 109 : Meitnerium (Mt)
    • Chien-Shiung Wu “Thefirst Lady ofPhisycs” ▪ Shanghai in 1912, one year after the Chinese revolution started ▪ Her father created a clandestine school for her to study in ▪ In 1930 she leads a demonstration for women to gain access to universities in Nanjing ▪ She acquires her degree in 1934 and moves to Shanghai ▪ In 1936 she emigrates to the US to start a Ph.D. In Physics
    • Chien-ShiungWu:firststeps ▪ She gets her Ph.D. In Physics under the supervision of Ernst O. Lawrence and Emilio Segré ▪ Fermi and Oppenheimer referred to her as “the authority” and coin the phrase “Ask Miss Wu”. ▪ After the bombing of PH she is haunted by xenophobia which forces her to work at a College in Northampton ▪ Finally she receives a temporary position in Princenton ▪ After the war she receives a permanent position at Columbia university ▪ She makes relevant contributions on beta decay
    • Chien-Shiung Wu : Thediscoveryofparityviolation ▪ 1956 Lee andYang published a theoretical article where they questioned the parity violation on the weak interaction ▪ Wu proves with a simple and elegant experiment that the parity is not conserved under the weak nuclear interaction ▪ 1957 Lee andYang received the Noble Prize in Physics

    • Bernie Poiesz “There are many different reasons why people associate Robert Gallo’s name as the discovered of HTLV, I can’t change how people perceive it, or how people presented it to the media.The only thing I can do is do my work. I spent many many nights in that laboratory. The moment of discovery was mine.” (Nature, P.A. Lawrence. 2002) “Existen muchas razones por las cuales la gente asocia el nombre de Robert Gallo al descrubrimiento del HTLV, no puedo cambiar la percepción popular, ni cómo los medios de comunicación lo han presentado. Solo puedo hacer mi trabajo. Pasé muchas noches en el laboratorio. El momento del descubrimiento fue mío. ”

    • Nature 387, 341 (1997) ¿ Han mejorado las cosas? Indudablemente, pero queda mucho trabajo por hacer… Academia de Medicina Sueca -44% Ph.D. con honores -25% hacen postdoctorados -7% profesión -Menor motivación ? -Menor producción ? -Discriminación? El ratio de éxito de las solicitudes femeninas en Swedish Medical ResearchCouncil era la mitad que el de los hombres.
