Bertha Mason was born in 1855, the eldest daughter of Betsey and Hugh Mason. She grew up in Ashton-under-Lyne. Hugh Mason owned a mill and she was raised in relative comfort, although her mother died in 1861. Little is known of her education. Mason grew up in at atmosphere in which issues such as Liberalism, temperance and women’s enfranchisement were openly discussed. As LiberalMember of Parliament for Ashton under Lyne, her father had proposed a resolution on women being able to vote in 1880 and he was associated with the Central Committee for Women's Suffrage, the Manchester Society for Women's Suffrage and the Manchester and Salford Temperance Union.
Career
Mason wrote in her 1912 book The Story of the Women Suffrage Movement that she herself became involved in 1890. By 1894, she was participating in both the Manchester National Society for Women’s Suffrage and the Central National Society for Women’s Suffrage. When the former group changed into the North of England Women’s Suffrage Society, she acted as chairperson until 1903. She was also politically active more generally, taking on various committee roles in the Ashton Women’s Liberal Association, the Lancashire and Cheshire Union of Women’s Liberal Associations and the Lancashire Union of the British Women’s Temperance Association. From around 1902 onwards she was involved in the National Union of Women’s Suffrage Societies. Addressing the junior members of the British Women’s Temperance Association in 1903, she told her audience "You are citizens of a State, whether you know it or not" and emphasised that "You will come to realise that the housing of the poor, the protection of infant life, the safeguarding of the workers, the care of the aged, the mentally afflicted, the education of the young, are your business, your concern." Mason moved to London in 1904, living at 9 Hyde Park Place. She took on committee roles in the Women’s Local Government Society and the Central Society for Women’s Suffrage. Her salon became a place for activist meetings. Mason prepared a slide show and lecture in the late 1900s, which was summarised as "pictures of unique interest of the forerunners of the movement, the advance guard, the parliamentary champions, the present day workers, election incidents". She toured NUWSS groups giving the lecture in places such as Bath, Croydon and Mansfield, and this then became the basis of her book, published in 1912. A review published the same year in The Common Cause magazine called it "a concise history of the leading events of the history of Women's Suffrage". Alongside books by Helen Blackburn and Millicent Fawcett, The Story of the Women Suffrage Movement is regarded as an official account of the Suffragist movement, focusing on a slow, continuous progression towards victory which neglects to mention some of the conflictual issues. During the First World War, Mason joined the British Committee of the French Red Cross working in kitchens in France. After the war, she resumed her activism, becoming chairperson of the Women’s Local Government Society. She also served on the National Council of Women of Great Britain and the Women’s Advisory Council of the League of Nations.
Death and legacy
Mason had moved out of London to Hindhead, Surrey, but died on 8 July 1939 at the Hans Crescent Hotel in Knightsbridge, London. She was cremated at Golders Green crematorium and had expressed the wish for her ashes to be scattered near where her sister Edith lay in the cemetery at Worthenbury in Wales. She left in her will and made a legacy to the Ashton-under-Lyne District Infirmary and Childrens’ Hospital, where two beds were kept in memory of her father and sister.
