The Story of the Stethoscope

One might not automatically recognise the image below as that of an early version of the medical stethoscope. It certainly looks very different today. This blog focuses on the invention of this instrument, synonymous with the medical profession, over 200 years ago.

Where did it all begin?

The story of the invention of the stethoscope begins with a young French physician in Paris, René Laennec. It was in 1816 that Laennec was called to see a rather fat and buxom young woman with a ‘diseased heart’. Feeling awkward, embarrassed and improper at putting his ear so close to this woman’s chest in an attempt to listen to her heart, Laennec sought to find an alternative method. He described his predicament and later actions in the medical text De l’Auscultation Médiate, published in August 1819:

I happened to recollect a simple and well-known fact in acoustics, … the great distinctness with which we hear the scratch of a pin at one end of a piece of wood on applying our ear to the other… I rolled a quire of paper into a kind of cylinder and applied one end of it to the region of the heart and the other to my ear, and was not a little surprised and pleased to find that I could thereby perceive the action of the heart in a manner much more clear and distinct than I had ever been able to do by the immediate application of my ear.’

Laennec modified this method of a rolled up piece of paper to make a wooden cylinder, measuring 25cm by 2.5cm. He called this piece of equipment a ‘stethoscope’, the name derived from the ancient Greek stethos meaning ‘chest’, and skopein meaning ‘look at’. The stethoscope became an essential item in Laennec’s medical bag and he utilised it to listen to both the heart and lungs of his patients.

 

Reception

Although a few physicians resisted the introduction of the stethoscope, maintaining that it was best to listen only with one’s ear, the vast majority of the medical profession embraced its use. The invention quickly spread over Europe in the early 1820s and the design was further developed and improved upon. By the end of the nineteenth century, this wooden instrument had morphed into something more akin to the modern-day stethoscope. Flexible tubing, first made out of rubber, and then plastic, made the stethoscope both easier to use and transport; whilst binaural earpieces improved the quality of the sound for the listener. The stethoscope works by transmitting acoustic pressure waves from the chest-piece through the hollow tubes to the listener’s ears. Today, there are even more advanced electronic stethoscopes which amplify body sounds improving further the sound transmitted.

The meaning of the stethoscope

The significance of a stethoscope in the twenty-first century cannot be under-estimated. It confers identity and, to a certain degree, status. Its wearer is automatically assured to be a member of the medical profession. It implies trust, understanding and knowledge. In this way, Laennec’s stethoscope is incredibly valuable, both from a diagnostic and symbolic perspective.

The Flint Water Crisis: have lessons from history been forgotten (again)?

‘That men do not learn very much from the lessons of history is the most important of all lessons that history has to teach’Aldous Huxley

The Flint Water Crisis, which started in 2014 and is still on-going, is a contemporary example of where lessons from history have been ignored.  Briefly, the authorities in Flint, Michigan, decided to replace the water supply from Lake Huron with the less expensive water from the Flint River. Unfortunately, the Flint River was heavily polluted and this led to Legionnaire’s disease and lead poisoning among residents using the water supplied by lead pipes. Of particular concern is the expert opinion that almost 9,000 Flint children are at risk of developmental difficulties and long-term conditions due to lead poisoning. The authorities have been heavily criticised for not testing the safety of the Flint river water in advance and for the delays in both accepting that there was a problem, and in implementing the changes necessary to supply safe water. The crisis has sparked intense political and media debate and several prosecutions are pending.

In the nineteenth century, several reports of lead poisoning secondary to lead pipes in Britain and the USA appeared in the medical literature and the popular press. The problem in Britain was widespread but particularly evident in Yorkshire, Lancashire and Scotland. In Sheffield, the problem was first reported in 1885 by the Medical Officer of Health and was traced to the water from one reservoir that corroded lead supply pipes and lead-lined cisterns, hence contaminating the domestic water supply. The resistant Sheffield Water Company only agreed to add lime to the water after a public inquiry in 1890. Of even greater concern is the shocking 120 year delay in accepting that lead poisoning in Glasgow was due to a combination of the water supply from Loch Katrine and lead supply pipes.

Could the Flint water crisis happen again? Yes, sadly it could, and the words of Huxley resonate strongly here. But, if we listen to the lessons of history, and learn from them, such needless harm can be prevented.

Elizabeth Garrett Anderson: a modern woman 100 years ahead of her time

As a junior doctor possessing two X chromosomes, it is easy to applaud the achievements of Elizabeth Garrett Anderson (1836-1917), widely revered as the first British female doctor. It is infinitely harder to establish exactly how she succeeded and to quantify the relevance of this extraordinary woman who died just over 100 years ago. Can we still learn from her example, or has too much time passed to draw significant parallels in today’s modern world?

Elizabeth Garrett Anderson wrote to a friend in 1864: ‘My strength lies in the extra amount of daring which I have as a family endowment. All Garretts have it.’ EGA did have ‘daring’, and she wasn’t scared to do things differently. She is frequently referred to as ‘a pioneer’, and with just cause: EGA was the first woman to qualify in Britain to practice medicine, the first woman to qualify as a doctor of medicine in France, the founder of the first hospital staffed by women, the first female member of the British Medical Association (BMA), the first female Dean of a British medical school, the first female mayor in Britain; the list goes on. EGA’s nature as ‘the first’ engendered two conditions: one, that the medical profession as a whole had not expected, nor prepared, for the possibility of a female attempting admission to their ranks; and two, that any doors that remained open within the medical profession were swiftly slammed shut soon after EGA had passed through them. The permission for women to take the Licentiate of the Society of Apothecaries (LSA) examinations to obtain a medical degree, and admission of females to the BMA may be cited as examples here. Consequently, EGA’s nature as a ‘pioneer’ conferred a significant advantage, and it was initially harder, as opposed to easier, for women to qualify as doctors after Elizabeth Garrett Anderson had succeeded.

Not only did EGA have an unwavering belief in herself and her ability to become a doctor but she put her career first: this was unprecedented in mid-Victorian Britain. She married comparatively late, at the age of 34, despite the average age of contemporary females entering matrimony being just 23 years in 1871. Importantly, marriage took place only after she had successfully completed her studies to become a fully qualified doctor. She had previously declined an offer of marriage in 1865 from her sister Millicent’s future husband, the MP Henry Fawcett. Even after becoming engaged to James Skelton Anderson, she worried that this might jeopardise her career as a doctor and her fight for women’s suffrage: ‘I believe I should almost die of the sense of something akin to guilt, if I found myself, three years hence, really out of the medical field’. This excerpt clearly demonstrates an immense sense of duty. EGA felt herself carrying the weight of the future of women’s rights on her shoulders, and this was constantly in the forefront of her mind.

Elizabeth Garrett Anderson changed the course of women in medicine indefinitely, and more broadly, had an integral role in promoting the women’s suffrage movement on a national scale. Women today can identify with EGA given that she mastered the ability of the ‘modern woman’ to ‘have it all’ – with both a successful career and a fulfilling family life. In 1871, The Lancet proposed ‘if [Elizabeth Garrett Anderson] succeeds in combining the two functions of mistress of a household and medical practitioner, she will have performed a feat unprecedented in professional history, and added another notable incident to this annus mirabilis’.

Louisa Aldrich-Blake’s Casebook

On 25thApril, 1891, five-year-old Beatrice Saunders, drowsy and delirious, was brought to London’s Royal Free Hospital by her mother. Louisa Aldrich-Blake, a 25-year-old medical student, later to become an eminent surgeon, spent the next 10 days patiently documenting the progression of the little girl’s illness in her casebook (shown below). Beatrice died of tuberculous meningitis on 4thMay 1891. Aldrich-Blake’s casebook provides us with a valuable lens through which to view the education of a nineteenth-century female medical student.

Aldrich-Blake’s casebook, Wellcome Library, MS 5794.

This casebook is part of a collection of Louisa Aldrich-Blake’s clinical notes, written between 1887 and 1908, presented to the Wellcome Library in 1926. It documents a number of patient cases that Aldrich-Blake observed as a student on the wards.

Much of Aldrich-Blake’s documentation is in keeping with Nicholas Jewson’s concept of late nineteenth century ‘Hospital Medicine’. This can be appreciated in Aldrich-Blake’s record of a complete medical examination on admission of the patient to hospital. She adopts a logical systems-based approach: ‘nervous system’, ‘alimentary system’, respiratory system’ and ‘circulatory system’ are all examined thoroughly.

There is an overwhelming preoccupation with statistical analysis by way of patient observations in Aldrich-Blake’s account. Numerical data features strongly – the number of respirations, the heart rate and the temperature being specified several times. This is further emphasised through the inclusion of the patient’s observation chart (see below). In one sense, this renders the text obsolete: the account of the deteriorating child is distilled down to numbers on a graph, an objective depiction of life and death.

Observation chart, Wellcome Library, MS 5794.

30 hours after the patient’s death, an autopsy was performed, and the findings described in great detail. Of the seven pages that Aldrich-Blake used in her casebook to record this admission, a significant proportion (one-and-a-half pages) was dedicated to the post-mortem examination. This is in keeping with Jewson’s view of pathological anatomy as integral to Hospital Medicine.

However, elements of Aldrich-Blake’s documentation also correspond with Jewson’s notion of ‘Laboratory Medicine’, for example in the testing and analysing of bodily substances. Aldrich-Blake recorded the results of Beatrice’s urine analysis in her casebook: ‘Urine: acid. No alb. No sugar. Abundant urates’.

Despite these unquestionable features of ‘Laboratory Medicine’, Aldrich-Blake’s account also contains some aspects of ‘Bedside Medicine’, notably a diagnosis achieved via the patient’s self-report of their illness. Given that the focus of this case is a five-year-old child, clearly the patient would not be expected to provide a history herself. However, the mother does give such a report, and Aldrich-Blake’s inclusion of this highlights its significance:

 

Quite well up till April 22nd, no previous alteration in temperament. In the evening after coming home from school complained of headache and shivered. Early next morning had a severe fit of coughing of a peculiar character. After this she vomited and continued to do so after food or medicine until admission to R.F.H on April 25th.

 

Aldrich-Blake’s casebook entry demonstrates co-existing elements of ‘Bedside’, ‘Hospital’ and ‘Laboratory Medicine’ as described by Jewson. This casebook is a rich resource for helping us understand the practices of nineteenth-century medical professionals. It also provides us with some insight into the somewhat nuanced transition from bedside to hospital medicine.

Collecting “stuff”

Recently my wife and I have been trying to declutter our home; an emotional process that threatens domestic harmony and generates both relief and bereavement in equal measure. A lifetime of collected material artefacts and documents entombed in draws, cupboards or cardboard boxes are finally being subjected to the “William Morris test”: is it useful, is it beautiful?  If not, where should it go? Relatives, friends, the sale room, eBay, charity shops, the municipal tip, or a car-boot sale are places where “stuff” can be deposited. In this way, collections become fractured, and objects might lose both their identity and meaning.

This year the BSHM has celebrated collections and collectors through an excellent Poynter lecture “the Doctor as Collector ” by Simon Chaplin which is now available on this website at https://BSHM.org.uk/poynter-lecture/   and by our recent symposium “In Sickness and in Health ” with abstracts and lecture images at  https://bshm.org.uk/events/collections-symposium/

When James Parkinson (1755-1824), of eponymous disease fame, died, his collection of fossils, regarded as one of the finest in the UK, was inherited by his unappreciative wife. Sadly, she allowed the collection to be broken up and disposed of at a public sale. No catalogue exists and very few of the specimens can now be traced. A similar fate befell many other note-worthy “cabinets of curiosity” in the 18th an 19th centuries.

Readers of this blog may, like me, be reviewing their accumulated stuff.  If you have collections or archives that could be of interest to other medical historians please take steps to deposit these in an appropriate repository – archives, libraries or museums – where they can be properly conserved, catalogued and made available to others.
