Career:
Offered a research post in 1922 by W H Bragg (FRS 1907) to study the crystal structure of organic compounds by X-ray analysis; worked first at University College, London, then from 1923 at the Royal Institution, London. Working with W.T.Astbury began to apply space group theories to the study of X-ray diffraction patterns from crystals. Their important paper 'Tabulated data for the examination of the 230 space-groups by homogenous X-rays' was published by the Royal Society in 'Philosophical Transactions' in 1924. Went to Leeds (1927-1930), where she carried out important analyses of hexamethylbenzene and hexachlorobenzene crystals. International crystallographersd recognised the need for more comprehensive tables for crystal structure determination, and Lonsdale was a member of the editorial groupconcerned with the prpduction of new tables. She worked from home in the early 1930's follwing the birth of her first child, providing the structure factor formulae for each space group. The resulting 'International Tables', published in 1935, proved to be only the beginning of a project to shich she devoted much time and effort during the rest of her career, becoming Chaiman of the new Commission of Tables in 1948 and the principal editor in the production of the new volumes of 'International Tables' which first appeared in 1951. She returned to the Royal Institution in 1931 and remained there for the next fifteen years, concentrating on diamagnetic anisotropy, where her work on the magnetic anisotropy of benzil led to her studies of disorder in crystals caused by thermal motions, one of her principal research interests during the rest of her career. She was the first woman to be elected a Fellow of the Royal Society (1945); Reader in Crystallography, University College, London (1946), becoming Professor of Chemistry (1949). She established her own research school there and introduced two new courses in crystallography, one for undergraduates and the other for graduates. Among other wide interests, she studied methonium compounds, urinary calculi and synthetic diamonds, though her work on the 'International Tables' diverted much of her time from research. She developed divergent-beam X-ray photography of crystals and studied X-ray reflection by single crystals. She and her husband became members of the Society of Friends in 1935, which led to her refusal to register for civil defence duties, although she was willing to work as a volunteer. On her refusal to pay a fine for non-registration she was imprisoned in Holloway gaol for one month in 1943. This led to her taking an active interest in penal reform; she was made a member of the Board of Visitors, Aylesbury Prison for Women and Borstal Institution for Girls in 1949 and later served as Vice-Chairman of the Board of Visitors of a borstal in Essex. She was also concerned with world peace and ethics in science, becoming Vice-President of the Atomic Scientists Association and President of the Women's International League for Peace and Freedom. She attended several Pugwash Conferences on World Affairs and expressed her hope for peace in numerous articles, including a Penguin special 'Is Peace Possible?' and in lectures. She was Vice-President of the International Union of Crystallography (1960-19660, and President (1966); General Secretary of the British Association (1959-1964), President of the Physics Sections (1967) and President of the British Association (1967-1968), the first woman to hold the post. She received honorary degrees (DSc or LLD) from several universities including those of Wales, Leicester, Manchester, Oxford, Bath and Leeds.
