Marie Charlotte Carmichael Stopes (15 October 1880 – 2 October 1958) was a British author, palaeobotanist and campaigner for eugenics and women's rights. She made significant contributions to plant palaeontology and coal classification, and was the first female academic on the faculty of the University of Manchester. With her second husband, Humphrey Verdon Roe, Stopes founded the first birth control clinic in Britain. Stopes edited the newsletter Birth Control News, which gave explicit practical advice. Her sex manual Married Love (1918) was controversial and influential, and brought the subject of birth control into wide public discourse. Stopes publicly opposed abortion, arguing that the prevention of conception was all that was needed, though her actions in private were at odds with her public pronouncements.

Early life and educationEdit
Stopes was born in Edinburgh. Her father, Henry Stopes, was a brewer, engineer, architect and palaeontologist from Colchester. Her mother was Charlotte Carmichael Stopes, a Shakespearean scholar and women's rights campaigner from Edinburgh. At six weeks old, her parents took Stopes from Scotland; the family stayed briefly in Colchester then moved to London, where in 1880 her father bought 28 Cintra Park in Upper Norwood. Both of her parents were members of the British Association for the Advancement of Science, where they had met. Marie was taken to meetings where she met the famous scholars of the day. At first, she was home-schooled, but from 1892 to 1894 she attended St George's School for Girls in Edinburgh. Stopes was later sent to the North London Collegiate School, where she was a close friend of Olga Fröbe-Kapteyn.
Stopes attended University College London as a scholarship student, where she studied botany and geology; she graduated with a first class B.Sc. in 1902 after only two years by attending both day and night schools. Following this, Stopes earned a D.Sc. degree from University College London, becoming the youngest person in Britain to have done so. In 1903 she published a study of the botany of the recently dried-up Ebbsfleet River. After carrying out research on Carboniferous plants at the Royal Botanic Gardens, Kew, and at University College, London, she studied the reproduction of living cycads at the University of Munich, receiving a Ph.D. in botany in 1904. Also in 1904, she was one of the first women to be elected a fellow of the Linnean Society of London. She was also Fellow and sometime Lecturer in Palaeobotany at University College, London until 1920. She held the post of Lecturer in Palaeobotany at the University of Manchester from 1904 to 1910; in this capacity she became the first female academic of that university.
During Stopes's time at Manchester, she studied coal and coal balls and researched the collection of Glossopteris (Permian seed ferns). This was an attempt to prove the theory of Eduard Suess concerning the existence of Gondwana or Pangaea. A chance meeting with Antarctic explorer Robert Falcon Scott during one of his fund-raising lectures in 1904 brought a possibility of proving Suess's theory. Stopes's passion to prove Suess's theory led her to discuss the possibility of joining Scott's next expedition to Antarctica. She did not join the expedition, but Scott promised to bring back samples of fossils to provide evidence for the theory. Scott died during the 1912 Terra Nova Expedition, but fossils of plants from the Queen Maud Mountains found near Scott's and his companions' bodies provided this evidence.
In 1907, Stopes went to Japan on a scientific mission. She spent eighteen months at the Imperial University, Tokyo and explored coal mines on Hokkaido for fossilised plants. She published her Japanese experiences as a diary, called "Journal from Japan: a daily record of life as seen by a scientist", in 1910.
In 1910, the Geological Survey of Canada commissioned Stopes to determine the age of the Fern Ledges, a geological structure at Saint John, New Brunswick. It is part of the Early Pennsylvanian epoch Lancaster Formation. Canadian scholars were divided between dating it to the Devonian period or to the Pennsylvanian. Stopes arrived in North America before Christmas to start her research. On 29 December, she met the Canadian researcher Reginald Ruggles Gates in St. Louis, Missouri; they became engaged two days later. Starting her work on the Fern Ledges in earnest in February 1911, she did geological field work and researched at geological collections in museums, and shipped specimens to England for further investigation. The couple married in March and returned to England on 1 April that year. Stopes continued her research. In mid-1912 she delivered her results, finding for the Pennsylvanian period of the Carboniferous. The Government of Canada published her results in 1914. Later the same year, her marriage to Gates was annulled.
During the First World War, Stopes was engaged in studies of coal for the British government, which culminated in the writing of "Monograph on the constitution of coal" with R.V. Wheeler in 1918. The success of Stopes' work on marriage issues and birth control led her to reduce her scholarly work; her last scientific publications were in 1935. According to W. G. Chaloner (2005), "between 1903 and 1935 she published a series of palaeobotanical papers that placed her among the leading half-dozen British palaeobotanists of her time". Stopes made major contributions to knowledge of the earliest angiosperms, the formation of coal balls and the nature of coal macerals. The classification scheme and terminology she devised for coal are still being used. Stopes also wrote a popular book on palaeobotany, "Ancient Plants" (1910; Blackie, London), in what was called a successful pioneering effort to introduce the subject to non-scientists.
Around the start of her divorce proceedings in 1913, Stopes began to write a book about the way she thought marriage should work. In July 1913, she met Margaret Sanger, who had just given a talk on birth control at a Fabian Society meeting. Stopes showed Sanger her writings and sought her advice about a chapter on contraception. Stopes' book was finished by the end of 1913. She offered it to Blackie and Son, who declined. Several publishers refused the book because they thought it too controversial. When Binnie Dunlop, secretary of the Malthusian League, introduced her to Humphrey Verdon Roe—Stopes' future second husband—in 1917, she received the boost that helped her publish her book. Roe was a philanthropist interested in birth control; he paid Fifield & Co. to publish the work. The book was an instant success, requiring five editions in the first year, and elevated Stopes to national prominence.
Married Love was published on 26 March 1918; that day, Stopes was visiting Humphrey Roe, who had just returned with a broken ankle from service during the First World War after his aeroplane crashed. Less than two months later they were married and Stopes had her first opportunity to practise what she preached in her book. The success of Married Love encouraged Stopes to provide a follow-up; the already written Wise Parenthood: a Book for Married People, a manual on birth control that was published later that year. Many readers wrote to Stopes for personal advice, which she energetically endeavoured to give.
The following year, Stopes published A Letter to Working Mothers on how to have healthy children and avoid weakening pregnancies, a condensed version of Wise Parenthood aimed at the poor. It was a 16-page pamphlet and was to be distributed free of charge. Stopes's intended audience had—until this work—been the middle classes. She had shown little interest in, or respect for, the working classes; the Letter was aimed at redressing her bias.
On 16 July 1919, Stopes—pregnant and a month overdue—entered a nursing home. Stopes and the doctors clashed over the method of birth—she was not allowed to give birth on her knees. The child was stillborn; the doctors suggested the incident was due to syphilis, but an examination excluded the possibility. Stopes was furious and said her baby had been murdered. She was 38 years old.
When Stopes had sufficiently recovered she returned to work in 1920; she engaged in public speaking and responding to letters seeking advice on marriage, sex and birth control. She sent Mrs. E. B. Mayne to disseminate the Letter to Working Mothers to the slums of East London. Mayne approached twenty families a day, but after several months she concluded the working class was mistrustful of well-intentioned meddlers.
This lack of success made Stopes contemplate a different approach to taking her message to the poor. A conference of Anglican bishops was due to be held in June; not long before the conference, Stopes had a vision. She called in her secretary and dictated a message addressed to the bishops which began: "My Lords, I speak to you in the name of God. You are his priests. I am his prophet. I speak to you of the mysteries of man and woman." In 1922, Stopes wrote A New Gospel to All Peoples. The bishops were not receptive; among the resolutions carried during the conference was one aimed against "the deliberate cultivation of sexual union" and another against "indecent literature, suggestive plays and films [and] the open or secret sale of contraceptives". The Catholic Church's reaction was more strident, marking the start of a conflict that lasted the rest of Stopes' life.
In 1917, before meeting Marie Stopes, Humphrey Roe offered to endow a birth control clinic attached to St Mary's Hospital in Manchester. He proposed all patients would be married and that no abortions would be done, but his offer was declined. This was a serious issue for Roe; after their marriage, he and Stopes planned to open a clinic for poor mothers in London.
Margaret Sanger, another birth-control pioneer, had opened a birth control clinic in New York but the police closed it. In 1920, Sanger proposed opening a clinic in London; this encouraged Stopes to act more constructively, but her plan never materialised. Stopes resigned her lectureship at University College London at the end of 1920 to concentrate on the clinic; she founded the Society for Constructive Birth Control and Racial Progress, a support organisation for the clinic. Stopes explained that the object of the Society was:
“...to counteract the steady evil which has been growing for a good many years of the reduction of the birth rate just on the part of the thrifty, wise, well-contented, and the generally sound members of our community, and the reckless breeding from the C.3 end, and the semi-feebleminded, the careless, who are proportionately increasing in our community because of the slowing of the birth rate at the other end of the social scale. Statistics show that every year the birth rate from the worst end of our community is increasing in proportion to the birth rate at the better end, and it was in order to try to right that grave social danger that I embarked upon this work.”
On the printed notepaper is a list of prominent supporters which include the militant suffragette Lady Constance Lytton, feminist novelist Vera Brittain, Emily Pethick-Lawrence (former Treasurer of the Womens’ Social and Political Union), Rev Maude Royden (Women’s Suffrage Societies). Later supporters included eminent economist John Maynard Keynes. Three months later she and Roe opened the Mothers' Clinic at 61 Marlborough Road, Holloway, North London, on 17 March 1921. The clinic was run by midwives and supported by visiting doctors. It offered mothers birth control advice, taught them birth control methods and dispensed Stopes own "Pro-Race" (and later the "Racial") cervical caps.
The free clinic was open to all married women for knowledge about reproductive health. Stopes opposed abortion; she tried to discover alternatives for families and increase knowledge about birth control and the reproductive system. Options included the cervical cap—which was the most popular—coitus interruptus, and spermicides based on soap and oil. Stopes rediscovered the use of olive oil-soaked sponges as an alternative birth control. Olive oil's use as a spermicide dates to Greek and Roman times. Her recipe proved very effective. She tested many of her contraceptives on patients at her clinics.
Stopes became enthusiastic about a contraceptive device called the "gold pin", which was reportedly successful in America. A few months later, she asked Norman Haire, an Australian doctor, whether he would be interested in running a clinical trial of the device, as she had two correspondents who wanted to use it. Haire had already investigated the device and found it to be dangerous. Haire became involved in another birth control clinic that opened in Walworth in November 1921; later a rivalry between Stopes and Haire erupted in The Lancet. Haire brought up the gold-pin episode, even though Stopes' clinic had never used it. The issue of the gold pin device resurfaced in the Stopes-Sutherland libel case a few years later.
In 1925, the Mothers' Clinic moved to Central London, where it remains as of 2015[update]. Stopes gradually built up a small network of clinics across Britain, working to fund them. She opened clinics in Leeds in April 1934; Aberdeen in October 1934; Belfast in October 1936; Cardiff in October 1937; and Swansea in January 1943.
The Marie Stopes International organisationEdit

The clinics continued to operate after Stopes' death, but by the early 1970s they were in financial difficulties and in 1975 they went into voluntary receivership. Marie Stopes International was established a year later as an international non-governmental organisation (NGO) working on sexual and reproductive health. The global partnership took over responsibility for the main clinic, and in 1978 it began its work overseas in New Delhi, India. Since then the organisation has grown steadily; today it works in over 40 countries, has 452 clinics and has offices in London, Brussels, Melbourne and in the US.
Opposition and libel caseEdit
In 1922, Dr Halliday Sutherland wrote a book called Birth Control: A Statement of Christian Doctrine Against the Neo Malthusians. In the inter-war years, the terms "birth control" and "eugenics" were closely related; according to Jane Carey they were "so intertwined as to be synonymous".
Following attacks on "the essential fallacies of Malthusian teaching", Sutherland's book attacked Stopes. Under the headings "Specially Hurtful to the Poor" and "Exposing the Poor to Experiment", it read:
In the midst of a London slum a woman, who is a doctor of German philosophy (Munich), has opened a Birth Control Clinic, where working women are instructed in a method of contraception described by Professor McIlroy as ‘The most harmful method of which I have had experience’. When we remember that millions are being spent by the Ministry of Health and by Local Authorities – on pure milk for necessitous expectant and nursing mothers, on Maternity Clinics to guard the health of mothers before and after childbirth, for the provision of skilled midwives, and on Infant Welfare Centres – it is truly amazing that this monstrous campaign of birth control should be tolerated by the Home Secretary. Charles Bradlaugh was condemned to jail for a less serious crime.
Stopes was incensed. The reference to "doctor of German philosophy" sought to undermine Stopes because she was not a medical doctor and, being so soon after the First World War, sought to harness anti-German sentiment. Stopes' work had been associated with Charles Bradlaugh, who had been convicted of obscenity 45 years earlier when he had republished an American Malthusian text in Britain, which "advocated and gave explicit information about contraceptive methods". Stopes challenged Sutherland to a public debate. When Sutherland did not respond, she brought a writ for libel against him. The court case began on 21 February 1923; it was acrimonious. Four questions were put to the jury, which they answered as follows:
- Were the words complained of defamatory of the plaintiff? Yes.
- Were they true in substance and in fact? Yes.
- Were they fair comment? No.
- Damages, if any? £100.
Based on the jury’s verdict, barristers for both sides asked for judgement in their favour, so it came down to legal argument. Sutherland’s barrister successfully argued that as soon as the jury decided that the statements were true in substance and in fact, that was the end of the matter. It was a moral victory for Stopes as the press saw it, and she appealed. On 20 July, the Court of Appeal reversed the previous decision (2-1), awarding the £100 to Stopes. The Catholic community mobilised to support Sutherland (himself a Catholic) and Stopes publicly campaigned to raise £10,000. Sutherland made a final appeal to the House of Lords on 21 November 1924. The trial had made birth control a public topic and the number of clients visiting the clinic doubled. The Law Lords found in Sutherland's favour, 4-1, and their decision was irrevocable. The cost for Stopes was vast; costs were partially compensated by publicity and book sales.
Stopes was even remembered in a playground rhyme:
Jeanie, Jeanie, full of hopes,
Read a book by Marie Stopes,
But, to judge from her condition,
She must have read the wrong edition.
If through a mist of awful fears,
Your mind in anguish gropes,
Dry up your panic-stricken tears
And fly to Marie Stopes.
If you have missed life's shining goal
And mixed with sex perverts and Dopes,
For normal soap to cleanse your soul
Apply to Marie Stopes.
And if perhaps you fail all round
And lie among your shattered hopes,
Just raise your body from the ground,
And crawl to Marie Stopes.
Stopes was acquainted with many literary figures of the day. She had longstanding correspondences with George Bernard Shaw and Aylmer Maude, and argued with H. G. Wells. Noël Coward wrote a poem about her, and she edited Lord Alfred Douglas' letters. She unsuccessfully petitioned Neville Chamberlain to arrange for Douglas to receive a civil list pension; the petition was signed by Arthur Quiller-Couch, John Gielgud, Evelyn Waugh and Virginia Woolf, among others. The general secretary of the Poetry Society, Muriel Spark, had an altercation with Stopes; according to Mark Bostridge, Spark "found herself lamenting that Stopes's mother had not been better informed on [birth control]".
Stopes wrote poems and plays; during the First World War she wrote increasingly didactic plays. Her first major success was Our Ostriches, a play that dealt with society's approach to working class women being forced to produce babies throughout their lives. The play ran for three months at the Royal Court Theatre. It was hurriedly produced in place of Vectia, another of Stopes' plays. Vectia is an autobiographical attempt to analyse the failure of Stopes' first marriage. Because of its themes of sex and impotence, it was denied a licence to be performed, despite Stopes's frequent efforts. In 1926, Stopes had Vectia printed under the title A Banned Play and a Preface on Censorship. None of her later plays reached the stage.
Stopes published several volumes of poetry in her later years. Among them are Love Songs for Young Lovers (1939) and Oriri (1940).
Views on abortionEdit
Publicly, Stopes professed to oppose abortion and, during her lifetime, her clinics did not offer that service. She single-mindedly pursued abortionists and used the police and the courts to prosecute them. Stopes thought that the use of contraceptives was the preferred means by which families should voluntarily limit their number of offspring. Nurses at Stopes' clinic had to sign a declaration not to "impart any information or lend any assistance whatsoever to any person calculated to lead to the destruction in utero of the products of conception". When Stopes learned that one of Avro Manhattan's friends had had an abortion, Stopes accused him of murdering the unborn child.
Her private actions were, however, at odds with her public pronouncements. In a 1919 letter, she had outlined a method of abortion to an unidentified correspondent and she “was even prepared in some cases to advocate abortion, or, as she preferred to put it, the evacuation of the uterus”. Further, in “Wise Parenthood” she had promoted the "Gold Pin" or "Spring" which was a “method [that] could be described as an abortifacient”.
In her biography of Stopes, June Rose claimed "Marie was an elitist, an idealist, interested in creating a society in which only the best and beautiful should survive," a view echoed by Richard A. Soloway in the 1996 Galton Lecture: "If Stopes' general interest in birth control was a logical consequence of her romantic preoccupation with compatible sexuality within blissful marriage, her particular efforts to provide birth control for the poor had far more to do with her eugenic concerns about the impending 'racial darkness' that the adoption of contraception promised to illuminate." 
Stopes’ enthusiasm for eugenics and race improvement was in line with many intellectuals and public figures of the time, for example, Havelock Ellis, Cyril Burt and George Bernard Shaw. Eugenic sympathies were drawn from the left and the right of politics and included feminists and Labour politicians, such as Ellen Wilkinson. As a child Marie had met Francis Galton, one of the founders of modern Eugenics, through her father. She joined the Eugenics Education Society in 1912 and became a life fellow in 1921. Clare Debenham in her 2018 biography of Stopes argues in Chapter Nine that she was a maverick Eugenicist, who was shunned by the inner circle of the Eugenic Society. In 1934, she reflected: “I am a Life Fellow and would have much more interest in the Eugenics Society if I had not been cold shouldered.”
At first Marie used Eugenic terminology when she felt it would suit her purpose but later dropped Eugenics references.
The objects of the Society For Constructive Birth Control and Racial Progress revealed its eugenic aims, summarised in point 16: "In short, we are profoundly and fundamentally a pro-baby organisation, in favour of producing the largest possible of healthy, happy children without detriment to the mother, and with the minimum wastage of infants by premature deaths. In this connection our motto has been 'Babies in the right place,' and it is just as much the aim of Constructive Birth Control to secure conception to those married people who are healthy, childless, and desire children, as it is to furnish security from conception to those who are racially diseased, already overburdened with children, or in any specific way unfitted for parenthood." Stopes advocated the compulsory sterilisation of those she considered unfit for parenthood in 1918 and in 1920.
In Chapter XX of her 1920 book “Radiant Motherhood” Stopes discussed race and said that the "one central reform" was: “The power of the mother, consciously exerted in the voluntary procreation and joyous bearing of her children, is the greatest power in the world.” She added that two "main dangers" stood in the way. The first of these was ignorance and the second was the "inborn incapacity which lies in the vast and ever increasing stock of degenerate, feeble-minded and unbalanced who are now in our midst and who devastate social customs. These populate most rapidly and tend proportionately to increase and these are like the parasite upon the healthy tree sapping its vitality." Stopes then stated that "a few quite simple acts of Parliament" could deal with "this prolific depravity": sterilisation by x-rays and assured the reader that “when Bills are passed to ensure the sterility of the hopelessly rotten and racially diseased, and to provide for the education of the child-bearing woman so that she spaces her children healthily, our race will rapidly quell the stream of the depraved, hopeless and wretched lives which are at present increasing in proportion in our midst."
Stopes promoted her eugenic ideas to politicians. In 1920, she sent a copy of her book, "Radiant Motherhood"—arguably the most explicitly eugenic of her books—to the Prime Minister's secretary, Frances Stevenson, and urged her to get Lloyd George to read them. In November 1922, just before the General Election, she sent a questionnaire to parliamentary candidates asking that they sign a declaration that: "I agree that the present position of breeding chiefly from the C3 population and burdening and discouraging the A1 is nationally deplorable, and if I am elected to Parliament I will press the Ministry of Health to give such scientific information through the Ante-natal Clinics, Welfare Centres and other institutions in its control as will curtail the C3 and increase the A1". She received 150 replies.
In July 1931 the Women’s Co-operative Guild at their conference passed a resolution advocating compulsory sterilisation for the mentally or physically unfit.
A 1933 letter from Stopes to a friend revealed disillusion with Eugenics: “I do not think I want to write a book about Eugenics. The word has been so tarnished by some people that they are not going to get my name tacked onto it.”  Despite this, she attended the International Congress for Population Science in Berlin in 1935 and, on her death in 1958, she bequeathed her clinics to the Eugenics Society.
In 1934, an interview published in the Australian Women's Weekly disclosed Marie's views on mixed-race marriages: she advised correspondents against them and believed that all half-castes be sterilised at birth...thus painlessly and in no way interfering with the individual's life, the unhappy fate of he who is neither black nor white is prevented from being passed on to yet unborn babes.
Arguably Marie had more than a touch of megalomania as seen in her contacts with world leaders. In August 1939 sent a copy of her “Love Song for Young Lovers” to Adolf Hitler because “Love is the greatest thing in the world”. She wanted her poems to be distributed through the German birth control clinics. However, according to Rose any sympathy she may have had with Hitler would have been dissipated when he closed those clinics. In 12 July 1940 she wrote to Winston Churchill to offer a slogan, “Fight the Battle of Britain in Berlin’s Air”.
Stopes had a relationship, mainly through correspondence, with Japanese botanist Kenjiro Fujii, whom she met at the University of Munich in 1904 while researching her Ph.D. In 1907, during her 1904–1910 tenure at Manchester University, she arranged to research in Japan, allowing her to be with Fujii. The relationship ended.
In 1911, Stopes married Canadian geneticist Reginald Ruggles Gates. She had maintained her name out of principle; her work was blooming while his was struggling. He was disturbed by what he considered her suffragette support. He failed to assert his position as head of the household and was frustrated. The marriage fell apart amid squabbling over the house and rent. After another year, she sought legal advice about ending the marriage. Not receiving useful help, she read the legal code seeking a way to get a divorce. On 11 May 1913, Stopes filed for divorce on the grounds that the marriage had never been consummated. Gates left England the following year and did not contest the divorce.
In 1918 she married Humphrey Verdon Roe, the financial backer of her most famous work, Married Love: A New Contribution to the Solution of the Sex Difficulties. Their son, Harry Stopes-Roe, was born in 1924. Stopes disliked Harry's companion, Mary Eyre Wallis, who was the daughter of the noted engineer Barnes Wallis. When Harry announced their engagement in October 1947, his mother set about "to try to sabotage the union". She found fault with Mary and wrote to Mary's father to complain. She tried to get Humphrey's support against the marriage, arguing that any grandchildren might inherit Mary's myopia. He was not persuaded. Later, believing "he had betrayed her by this marriage", Stopes cut him out of any substantial inheritance.
In 1923, Marie Stopes bought the Old Higher Lighthouse on the Isle of Portland, Dorset, as an escape from the difficult climate of London during her court case against Halliday Sutherland. The island's Jurassic fossil forests provided her with endless interest. She founded and curated the Portland Museum, which opened in 1930. The cottage housing the museum was an inspiration behind The Well-Beloved, a novel by Thomas Hardy, who was a friend of Marie Stopes.
Stopes died on 2 October 1958, aged 77, from breast cancer at her home in Dorking, Surrey. Her will left her clinic to the Eugenics Society; most of her estate went to the Royal Society of Literature. Her son Harry received her copy of the Greater Oxford Dictionary and other small items. An English Heritage blue plaque commemorates Stopes at 28 Cintra Park, Upper Norwood, where she lived from 1880 to 1892.
