Introduction

In the early twentieth century, the theory of eugenics was widely accepted in Britain amongst the medical and scientific establishments, politicians and public intellectuals. Its advocates believed that selective reproduction could improve Britain’s “racial stocks” and reduce the perceived burden of illness and poverty.

Dr Halliday Sutherland’s work, however, led him to challenge this consensus. Drawing on his medical experience treating tuberculosis among the urban poor, he rejected the core assumptions of eugenics. He argued that poverty and disease arose from social and environmental problems, not from hereditary defects. His opposition, expressed in books, lectures, and ultimately the 1923 Stopes v. Sutherland libel trial, placed him among the earliest and most consistent critics of eugenic thinking in Britain.

This page sets out the historical context of eugenics and outlines Sutherland’s scientific and ethical objections, drawing on contemporary sources and his published work.

What Was Eugenics?

Definition

The term eugenics was defined by Sir Francis Galton in 1904 to describe the application of selective breeding principles to human populations. Galton and his followers argued that society could be improved by encouraging reproduction among those deemed “fit” and discouraging or preventing reproduction among those labelled “unfit.”

In Britain, eugenics gained institutional support through organisations such as the Eugenics Education Society, research laboratories, academic faculties, and an expanding academic literature.

Mainstream standing

At the time, eugenics was widely accepted across the political spectrum. Many prominent scientists, social reformers, and commentators advocated eugenic principles. Arguments for compulsory sterilisation, marriage restriction, and the segregation of the “unfit” appeared in respected journals and public debates.

Eugenics was not viewed by its supporters as extremist but as a scientific solution to social problems.

How did Eugenics Relate to Public Health in Britain?

Public health reformers in the late nineteenth and early twentieth centuries faced the dual challenges of infectious disease and urban poverty. Some, influenced by hereditarian thinking, argued that disease and destitution resulted from defective stock rather than environmental conditions.

Eugenic ideas dovetailed with concerns about national efficiency, military fitness, and the economic costs of poverty. As a result, eugenic theories increasingly informed public policy proposals related to social care, housing, and medical practice.

What was the Link Between Tuberculosis, Poverty, and Heredity?

Scientific Fault Line

Tuberculosis (Consumption) was among the leading causes of death in Britain when Sutherland began his medical career. Eugenicists viewed tuberculosis as hereditary (in other words they believed it arose from the inferior hereditary of the victims), for instance:

• Dr John Berry Haycraft in Darwinism and Race Progress (1895) “Sufferers from phthisis are prone to other diseases, such as pulmonary and bronchial attacks, so that over and above the vulnerability to this one form of microbe they are to be looked upon as unsuited not only for the battle of life, but especially for parentage and for the multiplication of the conditions from which they themselves suffer.”
• Karl Pearson in Tuberculosis, Heredity and Environment (1912) “… the bulk of the tuberculous belong to stocks which we want ab initio to discourage. Everything which tends to check the multiplication of the unfit, to emphasize the fertility of the physically and mentally healthy, will pro tanto aid Nature’s method of reducing the phthisical death-rate.”
• Sir James Barr in the President’s Address to the 80th Meeting of the British Medical Association (1912) “Nature on the other hand, weeds out those who have not got the inate power of recovery from disease, and by means of the tubercle bacillus and other pathogenic organisms she frequently does this before the reproductive age, so that a check is put on the multiplication of idiots and the feeble-minded. Nature’s methods are thus of advantage to the race rather than to the individual.”

What were Dr Halliday Sutherland’s Scientific Objections?

Sutherland, working directly among the poor in London, argued that tuberculosis was primarily an infectious disease of poverty. In 1911, he produced Britain’s first public-health cinema film The Story of John M’Neil the opening caption of which read: “Before you see the picture, it is necessary for all to realise that not only is tuberculosis CURABLE in its earlier stages, but above all it is PREVENTABLE.”

In 1912, Dr Sutherland’s The Soil and the Seed in Tuberculosis was published in the British Medical Journal in which he concluded that tuberculosis was primarily an infectious condition: “Therefore it is not heredity which determines whether the children of consumptives will develop the disease, but the existence of certain immediate factors which are under our control.”

In a 1917 speech Consumption: Its Cause and Cure Dr Sutherland identified eugenicists as a major obstacle to the prevention and cure of Consumption:

“But why should you set out to prevent this infection and to cure the disease? There are some self-styled eugenists—whom you, Sir, from your pulpit have castigated as race breeders with the souls of cattle-breeders—who declaim that the prevention of disease is not in itself a good thing. They say the efficiency of the State is based upon what they call ‘the survival of the fittest.’ This war has smashed their rhetorical phrase. Who talks now about survival of the fittest, or thinks himself fit because he survives? I don’t know what they mean. I do know that in preventing disease you are not preserving the weak, but conserving the strong. And I do know that those evil conditions which will kill a weakly child within a few months of birth, and slay another when he reaches the teens, will destroy yet another when he comes to adult life.”

What Were Dr Halliday Sutherland’s Ethical and Social Concerns?

The causes of poverty

Prior to writing Birth Control, Sutherland wrote a pamphlet for the Catholic Truth Society called Do Babies Build Slums? The title challenged the assumption that the birth-rate of the poor was the cause of their poverty. In Birth Control, he developed his argument:

“2. Poverty in Britain due to other causes

“(a) Under-development. Even if the theory of birth controllers, that a high birth-rate increases poverty, were as true as it is false, it could not possibly apply to Great Britain or to any other country open to commercial intercourse with the world because there is no evidence that the supply of food in the world either cannot or will not be increased to meet any actual or possible demand. Within the British Empire alone there was an increase of 75 per cent. in the production of wheat between 1901 and 1911. In Great Britain there has been not only an increase of population but also an increased consumption of various foods per head of the population. Moreover, if Britain were as well cultivated as is Flanders we could produce all or nearly all our own food.

“The truth is that in countries such as England, Belgium, and Bengal, usually cited by Malthusians as illustrating the misery that results from overpopulation, there is no evidence whatsoever to show that the population is pressing on the soil.

“On the contrary, we find ample physical resources sufficient to support the entire population, and we also find evidence of human injustice, incapacity, and corruption sufficient to account for the poverty and misery that exist in these countries. This was especially so in Ireland during the first half of the nineteenth century. Moreover, so far from high birth rates being the cause of poverty, we shall find that poverty is one of the causes of a high birth-rate.”

“(b) Severance of the Inhabitants from the Soil. It was not a high birth-rate that established organised poverty in England. In the sixteenth century the greater part of the land including common land belonging to the poor, was seized by the rich. They began by robbing the Catholic Church, and they ended by robbing the people. Once machinery was introduced in the eighteenth century, the total wealth of England was enormously increased; but the vast majority of the people had little share in this increase of wealth that accrued from machinery, because only a small portion of the people possessed capital. More children came, but they came to conditions of poverty and of child labour in the mills. In countries where more natural and stable social conditions exist, and where there are many small owners of land, large families, so far from being a cause of poverty are of the greatest assistance to their parents and to themselves. There are means by which poverty could be reduced, but artificial birth control would only increase the total poverty of the State, and therefore of the individual.

“From early down to Tudor times, the majority of the inhabitants of England lived on smallholdings. For example, in the fifteenth century there were twenty-one small holdings on a particular area measuring 160 acres. During the sixteenth century the number of holdings on this area had fallen to six, and in the seventeenth century the 160 acres became one farm. Occasionally an effort was made to check this process and by a statute of Elizabeth penalties were enacted against building any cottages “without laying four acres of land thereto.” On the other hand, acres upon acres were given to the larger landowners by a series of Acts for the enclosure of common land, whereby many labourers were deprived of their land. From the reign of George I to that of George III nearly four thousand enclosure bills were passed. These wrongs have not been righted.”

The “Servile State”

Sutherland feared that applying selective breeding theories to human society would erode respect for individual dignity and equality. He warned that eugenic policies threatened to create a stratified society in which the poor would not only lose reproductive rights, but would become the lowest strate in a servile state.

“(c) Tending towards the Servile State. Thirdly, the policy of birth control opens the way to an extension of the Servile State, because women as well as men could be placed under conditions of economic slavery. Hitherto, the rule has been that during child-bearing age a woman must be supported by her husband, and the general feeling of the community has been opposed to any conditions likely to force married women on to the industrial market. In her own home a woman works hard, but she is working for the benefit of her family and not directly for the benefit of a stranger. If, instead of bearing children, women practise birth control, and if children are to be denied to the poor as a privilege of the rich, then it would be very easy to exploit the women of the poorer classes. If women have no young children why should they be exempt of the economic pressure that is applied to men? And indeed, where birth control is practised women tend more and more to supplant men, especially in ill-paid grades of work. One of the birth controllers has suggested that young couples, who otherwise could not afford to marry, should marry but have no children, and thus continue to work at their respective employments during the day. As the girl would have little time for cooking and other domestic duties, this immoralist is practically subverting the very idea of a home! The English poor have already lost even the meaning of the word ‘property,’ and if the birth controllers had their way the meaning of the word ‘home’ would soon follow. The aim of birth control is generally masked by falsehood, but the urging of this policy on the poor points unmistakenly to the Servile State.”

In other words, he foresaw that eugenic policies would result in a state, where poverty was treated as hereditary defect and the poor were controlled rather than assisted.

He maintained that medical care and public health reforms rather than biological classification, were the correct response to the suffering caused by tuberculosis and consumption.

Predictions

Dr Sutherland predicted two developments in his writing namely, the depopulation of Britain and the use of a lethal chamber to kill the unfit.

The depopulation of Britain

In Birth Control and elsewhere, Dr Sutherland said that the proliferation of contraceptives would create a catastrophic drop in the birth rate. The book concluded:

“Our declining birth-rate is a fact of the utmost gravity, and a more serious position has never confronted the British people. Here in the midst of a great nation, at the end of a victorious war, the law of decline is working, and by that law the greatest empires in the world have perished. In comparison with that single fact all other dangers, be they war, of politics, or of disease, are of little moment. Attempts have already been made to avert the consequences by partial endowment of motherhood and by saving infant life. Physiologists are now seeking the endocrinous glands and the vitamins for a substance to assist procreation. “Where are my children?” was the question shouted yesterday from the cinemas. “Let us have children, children at any price,” will be the cry of tomorrow. And all these thoughts were once in the mind of Augustus, Emperor of the world from the Atlantic to the Euphrates, from Mount Atlas to the Danube and the Rhine. The Catholic Church has never taught that “an avalanche of children” should be brought into the world regardless of consequences. God is not mocked; as men sow, so shall they reap, and against a law of nature both the transient amelioration wrought by philanthropists and the subtle expediences of scientific politicians are alike futile. If our civilisation is to survive we must abandon those ideals that lead to decline. There is only one civilisation immune from decay, and that civilisation endures on the practical eugenics once taught by a united Christendom and now expounded almost solely by the Catholic Church.”

The lethal chamber

Heredity & Consumption appeared in the Westminster Gazette on 19 May 1922. In it, Dr Sutherland concluded: “Even if a Super-Eugenist, greatly daring, were to slay every consumptive in the land tonight, we should breed the disease afresh before tomorrow’s morn.”

Dr Sutherland’s short story The Perfect Eugenic State featured a lethal chamber to kill society’s misfits. It appeared in Britannia & Eve and In My Path in 1934

What was the Relationship between Eugenics and the Birth Control Movement?

Some historians state that the birth control and eugenics movements were distinct movements, while others conflate them. While there were those who advocated birth control for the purpose of family planning, such as Nurse E.S. Daniels and Professor Louise McIlroy, others came to contraception through the Malthusian League and the Eugenics Education Society which sought to improve the population by discouraging reproduction among the poor.

Marie Stopes was a member of the Malthusian League (the Secretary of the Malthusian League, Dr Binnie Dunlop, introduced Stopes to Humphrey Roe), She joined the Eugenics Education Society in 1912 and became a life fellow in 1921.

Was Marie Stopes a Eugenicist?

Marie Stopes, a prominent birth-control advocate, published eugenic arguments and called for restricting parenthood among those she considered “unfit.”

In 1918 Stopes took part in the National Birth Rate Commission in which she said: “May I suggest a very simple solution in regard to the hopelessly bad cases, bad through inherent disease, or drunkenness or character? A perfectly simple way would be sterilisation of the parent.”

She continued to advocate for compulsory sterelization of the unfit, for example, in Chapter 20 of Radiant Motherhood:

“It is, however, neither necessary to castrate nor is it suggested by those who, like myself, would like to see the sterilization of those totally unfit for parenthood made an immediate possibility, indeed made compulsory.”

… and suggested “few quite simple acts of Parliament to deal with it”. Sutherland challenged her approach, arguing that it risked “exposing the poor to experiment.” Their dispute culminated in the Stopes v. Sutherland trial (1923–1924), a major public confrontation over medical ethics, eugenics, and free speech.

Sterelization of the “Unfit”

On 21 July 1931, Major Archibald Church M.P. (Lab) rose in the House of Commons to propose a bill for the sterelization of mental defectives. He admitted that the measure was “… in advance of public opinion” and that, if it were adopted, it would be “merely a first step… before bringing in a Bill for the compulsory sterilization of the unfit.” The measure was defeated 89-167.

What is the Legacy of Eugenics?

Following the Second World War, the reputation of eugenics collapsed due to its association with coercive and discriminatory policies. In the face of this, the Eugenics Society (it changed its name in 1926) adopted a policy of crypto-eugenics to achieve its aims by stealth. Yet the ethical questions raised by Sutherland remain relevant in discussions of genetics, reproductive medicine, and public health.

His critique emphasised individual dignity, social justice, and the responsibilities of medicine toward the vulnerable — principles central to contemporary bioethics.

These question are as important today given that the eugenic idea continues and because the technology available to eugenicists today is way beyond that available to their counterparts of one-hundred-plus years ago.
