Deane was born in 1865. Four years after the death of her mother she became involved in 1890 with a charity called the National Health Society that provided training. In 1893 she and
Rose Squire became Britain's first women sanitary inspectors. They were based in Kensington and they inspected businesses that employed women. Squire became a factory inspector in 1894 and Deane followed a year later. She married architect
Granville Edward Stewart Streatfeild (1869-1947) DSO, OBE on 16 March 1911. Deane was a supporter of the
suffrage movement, being both a member of the
National Union of Women's Suffrage Societies and, in 1913, helping to organise a suffrage pilgrimage from Westerham and district, to the union's rally of 50,000 women in
Hyde Park. Amongst her other interests, Deane was a leading member of the
Women's Institute (founding a local branch in Westerham), and was involved in amateur theatre production. Lucy Deane died on 3 July 1950 in
Westerham, Kent, three years after the death of her husband. ==Career==
