Rosalind Franklin And DNA
''Rosalind Franklin and DNA'' is a biography of an English chemist Rosalind Franklin (1920–1958) written by her American friend Anne Sayre in 1975. Franklin was a physical chemist who made pivotal research in the discovery of the structure of DNA, known as "the most important discovery" in biology. DNA itself had become "life's most famous molecule". While working at the King's College London in 1951, she discovered two types of DNA called A-DNA and B-DNA. Her X-ray images of DNA indicated helical structure. Her X-ray image of B-DNA (called Photo 51) taken in 1952 became the best evidence for the structure of DNA. For the discovery of the correct chemical structure of DNA, the Nobel Prize in Physiology or Medicine 1962 was shared by her colleagues and close researchers James Watson, Francis Crick and Maurice Wilkins; she had died four years earlier in 1958 making her ineligible for the award. Background Rosalind Franklin joined King's College London in January 1951 to w ...

Rosalind Franklin
Rosalind Elsie Franklin (25 July 192016 April 1958) was a British chemist and X-ray crystallographer whose work was central to the understanding of the molecular structures of DNA (deoxyribonucleic acid), RNA (ribonucleic acid), viruses, coal, and graphite. Although her works on coal and viruses were appreciated in her lifetime, her contributions to the discovery of the structure of DNA were largely unrecognized during her life, for which she has been variously referred to as the "wronged heroine", the "dark lady of DNA", the "forgotten heroine", a "feminist icon", and the "Sylvia Plath of molecular biology". She graduated in 1941 with a degree in natural sciences from Newnham College, Cambridge, and then enrolled for a PhD in physical chemistry under Ronald George Wreyford Norrish, the 1920 Chair of Physical Chemistry at the University of Cambridge. Disappointed by Norrish's lack of enthusiasm, she took up a research position under the British Coal Utilisation Research Ass ...

Anne Sayre
Anne Sayre ( Colquhoun; April 10, 1923 – March 13, 1998) was an American writer well known for her biography of Rosalind Franklin, one of the discoverers of the structure of DNA. She was married to an American crystallographer David Sayre (1924–2012). Her literary contributions are in short stories, the earnings from which she supported her husband during his PhD course. She achieved her lifelong educational ambition of getting a law degree in her early 50s. She ultimately became justice of the local court in Head of the Harbor, New York. She was a lifelong friend of Franklin, who played a key role in the discovery of the chemical structure of DNA. A strong feminist, her 1975 book, ''Rosalind Franklin and DNA'', became an exposition of the account of sexism in the scientific community on one hand, and the true genius of the Rosalind Franklin in her contributions to molecular biology on the other hand. Biography Anne Sayre was "born on a train passing through Milwauke ...

John Randall (physicist)
Sir John Turton Randall, (23 March 1905 – 16 June 1984) was an English physicist and biophysicist, credited with radical improvement of the cavity magnetron, an essential component of centimetric wavelength radar, which was one of the keys to the Allied victory in the Second World War. It is also the key component of microwave ovens. Randall collaborated with Harry Boot, and they produced a valve that could spit out pulses of microwave radio energy on a wavelength of 10 cm. On the significance of their invention, Professor of military history at the University of Victoria in British Columbia, David Zimmerman, states: "The magnetron remains the essential radio tube for shortwave radio signals of all types. It not only changed the course of the war by allowing us to develop airborne radar systems, it remains the key piece of technology that lies at the heart of your microwave oven today. The cavity magnetron's invention changed the world." Randall also led the King's Col ...

Strangeways Laboratory
Strangeways Research Laboratory is a research institution in Cambridge, United Kingdom. It was founded by Thomas Strangeways in 1905 as the Cambridge Research Hospital and acquired its current name in 1928. Organised as an independent charity, it was historically funded primarily by the Medical Research Council and is currently managed by the University of Cambridge, also its sole trustee. Formerly a site of research on rheumatic arthritis and connective tissue disorders, it has since 1997 focused on the study of genetic epidemiology. History The institution was founded in 1905 as the Cambridge Research Hospital by physician Thomas Strangeways, who sought to study patients suffering from rheumatoid arthritis and related conditions. Funded by a combination of Strangeways' own contributions, support from noted doctors of the time, and donations from patients, the hospital began modestly with only six beds, and with research equipment located in renovated coal sheds. It closed ...

Jean Hanson
Emmeline Jean Hanson (14 November 1919 – 10 August 1973) was a biophysicist and zoologist known for her contributions to muscle research. Hanson gained her PhD in zoology from Bedford College, University of London before spending the majority of her career at a biophysics research unit at King's College London, where she was a founder member, and later its second Head. While working at Massachusetts Institute of Technology, she, with Hugh Huxley, discovered the mechanism of movement of muscle fibre in 1954, which came to known as "sliding filament theory". This was a groundbreaking research in muscle physiology, and for this BBC nicknamed her "Mrs Muscle" on the 50th anniversary of the discovery. Early life Hanson was born on 14 November 1919 in Newhall, Derbyshire, England, the only child of Tom and Emily Hanson. Her parents were both school teachers.

Purdah
Pardah or purdah (from Hindi-Urdu , , meaning "curtain") is a religious and social practice of female seclusion prevalent among some Muslim and Hindu communities. It takes two forms: physical segregation of the sexes and the requirement that women cover their bodies so as to cover their skin and conceal their form. A woman who practices purdah can be referred to as or . The term ''purdah'' is sometimes applied to similar practices in other parts of the world. Practices that restricted women's mobility and behavior existed among all religious groups since ancient times and intensified with the arrival of Islam. By the 19th century, purdah became customary among Hindu elites. Purdah was not traditionally observed by lower-class women. Physical segregation within buildings is achieved with judicious use of walls, curtains, and screens. A woman's withdrawal into purdah usually restricts her personal, social and economic activities outside her home. The usual purdah garment worn is ...

Feminism
Feminism is a range of socio-political movements and ideologies that aim to define and establish the political, economic, personal, and social equality of the sexes. Feminism incorporates the position that society prioritizes the male point of view and that women are treated unjustly in these societies. Efforts to change this include fighting against gender stereotypes and improving educational, professional, and interpersonal opportunities and outcomes for women. Feminist movements have campaigned and continue to campaign for women's rights, including the right to vote, run for public office, work, earn equal pay, own property, receive education, enter contracts, have equal rights within marriage, and maternity leave. Feminists have also worked to ensure access to contraception, legal abortions, and social integration and to protect women and girls from rape, sexual harassment, and domestic violence. Changes in female dress standards and acceptable physical act ...
