[1] Born in Madras, India, to British Army Lieutenant-Colonel Vivian Edward Muspratt and his wife, Lily May, née Hope.

Early in her career, Muspratt pursued both portraiture (especially of children) and experimental work; her solarization studies were influenced by the American artist Man Ray.

Her documentary work included travel to the Soviet Union in 1936 to photograph farmers and villagers along the Volga; upon her return, she joined the Communist Party in Britain.

Commissioned by the Left Book Club in 1937, she photographed miners and unemployed labourers in the Rhondda valley in south Wales.

[3] The Oxford premises of Ramsey & Muspratt had been a studio opened by Walter Benington on behalf of Elliott & Fry.
