Vision and touch — a material history of blindness

Our own Jan Eric Olsén has received 3.2 mill DKK (about 400.000 euro) from the Velux Foundation for a research project on the history of blindness, titled “Vision and touch: a material history of the world of blindness”.

Drawing on archival sources from the Danish Institute for the Blind and Visually Impaired, as well as the big ophthalmological and blind-historical collections in Medical Museion, the project will explore the medical and cultural tension between vision and blindness:

The material objects used by the blind and by emphasising the importance of the sense of touch, the project will provide an alternative viewpoint to earlier historical accounts of blindness and its complex relation to vision. By shifting focus from the iconography of blindness to the material objects used by the blind and by emphasising the importance of the sense of touch, the project will provide an alternative view-point to earlier historical accounts of blindness and its complex relation to vision.

Malaria museum coming up

We got this cuddly edition of the malaria parasite from Marco Herbst who was here visiting the museum last week, to get inspiration for his upcoming Malaria Museum in Berlin.

Marco’s approach to making a museum was refreshingly nontraditional. Far from being webbed up in museological concepts and theories, he builds on a growing fascination with his subject along with the human instinct to collect interesting things.

The former owner of a night club in Dublin and a bar in Berlin, Marco has some of the passion and personality of the renaissance collector with his cabinet of curiosities. I’m looking forward to popping by his museum for my daily gin and tonic – a drink originally invented to prevent malaria, as the tonic water contains the alkaloid quinine.

But of course background knowledge, and above all interesting objects, are essential. So Marco is at the moment traveling the world from Japan to Copenhagen, to meet malaria experts and museum people and ‘suck’ their knowledge.

The intensive care unit on display

One of my favourite fellow bloggers, medical photographer Øystein Horgmo, has just written about how he was recently invited to document a family taking farewell of a young father in an intensive care unit.

It’s a moving story. But what actually caught my interest was this painting (by medical doctor Joseph Dwaihy and artist Sara Dykstra), which Øystein uses the illustrate the story.

Based on a photograph from the Dartmouth-Hitchcock Medical Center’s first intensive care unit, circa 1955 (read more here), the painting is reminiscient of Norman Rockwell-realism. Like Rockwell, Dwaihy and Dykstra portray people in mundane situations. It’s people who play the primary role. The instruments are background props.

Compare Dwaihy and Dykstra’s painting of the 1955 ICU motif with a photo of a contemporary ICU unit. Today, there are indeed still people (a patient, a doctor, maybe a relative) around—but they seem to play a secondary role to the instruments.

In the cartoon below, the central role of instruments in an ICU is emphasized. The patient is invisible, the doctor is on his way out. Here the ICU is all about the instruments:

Why do we visit anatomical museums: for curiosity or for learning? (or maybe for some other reason?)

Plakat für ein anatomisches Museum, Hamburg, 1913

Next Friday, 17 December, Elena Corradini at the Università di Modena e Reggio Emilia organises a seminar on “Visiting an Anatomical Museum: curiosity or training?”:

Anatomical University Museums are the keepers of collections which often are very old and different for their consistence and typology. These museums have a fundamental role for the preservation and valorization of cultural historical‐scientific heritage, therefore must become a place of interdisciplinary synthesis. They represent the progress of studies in the past and for the future, and play their fundamental role for the research and for the promotion of educational activities. This role will allow them to be a service for University students and professors, and to spread scientific knowledge to different audiences. Developing the capacity of museums to work in a network is necessary for them to become centres for the production of knowledge, activities and services.

Speakers include a number of directors and curators from Italian university anatomical museums together with the directors of the Josephinum of Vienna and the Museum of Medical University of Danzig:

  • Giovanni Mazzotti, University of Bologna: Visiting an Anatomical Museum: curiosity or training?
  • Sonia Horn, University of Wien: The growth of collections for the permanence of an historical Anatomical Museum. The case of the Josephinum in Vienna.
  • Roberto Toni, University of Parma: The Anatomical Museum as a research source in the field of
    biomedical robotics: the Tenchini project at the University of Parma
  • Alessandro Ruggeri, Nicolò Nicoli Aldini, Stefano Durante, Vittorio Delfino Pesce, University of Bologna: The visit of the Anatomical Waxes Museum “Luigi Cattaneo” center of in-depth research of the Bolognese medical tradition of XIXth century and of training for modern education

We have cake and talk about diabetes

I had coffee and cake with our new PhD Adrian Bertoli the other day. Adrian is going to work with the relationship between type-2-diabetes and patient identity throughout the last 50 years, with Thomas as supervisor. Adrian’s project is financed by the cross-disciplinary Center for Healthy Ageing at Copenhagen University.

Knowledge about an illness is traditionally communicated directly from the doctor (the source) to the patient (the receiver). Adrian told me that he will look into how contemporary patient groups and social media on the internet make this kind of knowledge more accessible.

Knowledge is, seen from this angle, no longer something you receive from a single authoritative source but something that grows and gets its authority from its multiple authors. Knowledge is not something you get, it’s something you share.

Adrian is originally from Canada and when he arrived in Copenhagen a Danish network for foreign researchers in Denmark received him. They offered him a course in understanding the Danes, whom many foreigners experience to be somewhat closed and unwelcoming.

But in spite of freezing weather conditions and warnings about the Danes, Adrian feels at home here. Only a month after his arrival he was asked to give his first lecture in a course, and at the moment he holds an important post in the Medical Museion’s Christmas Party Committee.

The history of the microplate — a ubiquitous biomedical lab technology

One of my favourite objects for acquisition and display from the world of biomedical and clinical laboratories is the microplate (microtiter plate, microwell plate).

A microplate is simply a series of small test tubes (‘wells’) arranged in a regular matrix pattern on a plastic plate, usually made from transparent polystyrene.

The little plate makes it possible to handle many samples in parallell—the most common size is 96 wells, but there are plates with several thousand wells—and the results can be read in an automated plate reader. In addition, the small size of the wells reduces sample volumes (from milliliter scale to nanoliter scale), which in turn saves money spent on reagents, like enzymes, which can be forbiddingly expensive.

So it’s simple, low-tech, modest, cheap and cost-saving—no doubt the main reasons why the microplate is a ubiquitous tool in laboratories around the world for all kinds of biomedical research and clinical diagnostics. Most of today’s high-throughput analysis in genomics and proteomics is unthinkable without microplates.

In other words—the perfect lab technology.

What about the history of the microplate? Professional historians of medicine and/or technology haven’t paid much attention to the unassuming plastic lab device. After a few minutes on the web, however, I found out that the earliest microplate seems to have been constructed by the Hungarian medical microbiologist Gyula Takácsy (1914-1980). The Hungarian National Center for Epidemiology writes on their website that:

To respond to the shortage in laboratory supplies and a severe influenza outbreak in the early 50s in Hungary, Dr. Takácsy developed several excellent innovative lab supplies and techniques much ahead of his age. Describing his technical innovation, the spiral loop instead of pipette and glass-plates with wells instead of tubes, he used the term micromethods published in Hungarian in 1952 and in 1955 in English. He was the first to have the notion to apply calibrated spiral wire loops for multiple simultaneous serial dilutions in plastic multiwell strips.

“… very small volumes of blood taken from the fingertip or from laboratory animals can be taken up and diluted for quantitative work. The technique has been found particularly useful in virus research, since it is not negligible how much has to be used from costly immune sera and antigens”.

His paper focused on the use of spiral loops for serial dilutions and the testing methods for haemagglutination and complement fixation, however, the “8×12 grooves” that “can take up to 0.15 ml fluid” could describe the modern microplate.

So disease and shortage of supplies was apparently the mother of microplate invention. Also in the 1950s, US inventor John Liner (who founded a company called Linbro, which was later merged into Flow Laboratories Inc, which in turn was swallowed by ICN Flow, which is taken has been over by MTX Lab Systems; mergers and acquisitions in the medical and laboratory device industry is an extremely interesting history in its own right) introduced a vacuum-formed panel with 96 wells. Looking back in the late 1990′s, Liner wrote that “I consider myself  the grandfather to the disposable microplate, about 1953 I used a white styrene vacuum formed panel …”. Yet another case of multiple invention.

I also found some technical details about the early development of microplate automation here, and I found a reference to a web publication (Ray Manns, Microplate history. 2nd ed. 1999; http://www.microplate.org/history/det_hist.htm) in L.J. Kricka and S.R. Master, ‘Quality Control and Protein Microarrays’, Clinical Chemistry vol. 55: 1053–1055 (2009)—but the publication seems to be removed from the site.

So the microplate is almost untrodden territory for historians of medical technology. Maybe a medical student would like to explore its history and importance for the development of genomics and proteomics in a term paper?

Intro to ‘The Chemistry of Life’ exhibition as a joint science and art exhibition (beta version)

logo trykWe’ve just opened our new exhibition, ‘The Chemistry of Life’, in our satellite exhibition area in the main building of the Faculty of Health Sciences (the Panum Building). For the record, here’s the talk I gave at the opening (for images from the opening, see here):

The occasion for Medical Museion’s new exhibition, ’The Chemistry of Life’, is the new Center for Basic Metabolic Research here at the Faculty of Health Sciences.

But the Center is only the occasion. What you will see in a few minutes is not an exhibition about any of the aspects of metabolism—diabetes, or obesity, or insulin resistance, or the metabolic syndrome—which the Center will be focus on in the years to come.

Instead, we have chosen to take a look at the long research tradition that the Center has grown out of. We are presenting four snapshots from the long and complex history of metabolic research. Each snapshot represents a constellation of people, things and ideas from a significant phase in this history. And to make it easier for you to differentiate between these four constellations, we have given them different colours: green, orange, blue and lilac.

santoriolilleWe begin in Italy back in the early 17th century, where we examplify an early approach to metabolism with Santorio Santorio, a medical doctor in Padua, who made his way into the hall of fame of medical history, because he applied Galileo Galilei’s quantitative principle to physiology: “Measure what is measurable, and make measurable what is not”. For example, Santorio famously put himself in a chair balance to measure how his body lost weight even when no excretions could be registered.

Unfortunately, our tight budget hasn’t allowed us pay the insurance costs for borrowing original 17th century instruments from our Italian science museum colleagues. So to illustrate Santorio’s quantitative spirit, we had to find objects—balances, pulse meters, and thermometers—from later periods, in our own collections.

panumlilleThen we make a leap forward, more than 200 years in time, to Copenhagen in the mid-19th century, when Peter Ludvig Panum laid the foundation of the strong Danish tradition for experimental physiology. Medical Museion has a wonderful collection of instruments used by mid- and late century Danish physiologists—it’s every historical instrument collector’s dream-come-true (and one of the reasons why we soon need to strengthen the fire security around these internationally unique collections even more).

kroghlilleAgain a leap, now another 50 years, to the Nobel winning research done by August Krogh and by his wife Marie Krogh in the first decades of the 20th century. August Krogh was a pioneer in the study of whole-body gas exchange and also a very prolific inventor of instruments. We actually have quite a few of these in Medical Museion’s collections, and we are very proud to be able to display some of these in this show, for example this balance spirometer, which Marie Krogh used in her clinical studies of basic metabolic rates:

Picture6

And finally, the last leap. In the fourth (lilac) theme we are entering a territory, which historians so far have largely stayed away from, namely contemporary research in molecular metabolism, genomic research, genome-wide association studies and so forth. We are shaky grounds here, because we don’t have the historical distance to the events. molecularlilleAs historians, we don’t really know yet which the significant breakthroughs have been. We don’t know who the Santorios, the Panums and the Kroghs of contemporary molecular metabolic studies are. For us, these people are still Nomina Nescimus (unknown names), and therefore we need your help to identify them and their contributions. I’ll get back to this in a few minutes.

Like all serious science exhibitions, ‘The Chemistry of Life’ is actually research-based. The two main curators—postdoc Adam Bencard and former consultant Sven Erik Hansen—have read quite a lot from the 19th and 20th physiological literature, and spent months looking at objects and images in our collection. Every word in this exhibition has been chosen with great care, from both medical, historical and philosophical points of view. In one sense then (in terms of the making of it) this is a research-based exhibition. But in another sense (in terms of the way it presents itself to the spectator), we think of it rather as a work of art.

Not just as a display of works of art, like this painting by David Goodsell at Scripps Research Institute in La Jolla (which we commissioned from him specifically for this occasion):

Picture8

We also see the exhibition itself as an art installation. By taking things out of their laboratory context and placing them in this new setting, they are transformed, from being scientific objects to becoming art objects. Taken as a whole they constitute a joint science and art exhibition. Not sci-art, but joint science and art.

By thinking exhibitions about science in terms of art installations and art exhibitions, Medical Museion in joining a growing trend within the world of museums of science, technology and medicine. Most of these mueums still understand themselves as informal learning institutions. They want to make people, including students, interested in science by teaching the history of science.

But what we at Medical Museion – and some of our good colleagues, like the Wellcome Collection in London – are increasingly trying to do, is to work out an alternative to this didactical understanding of what science museums and their exhibitions are good for.

Instead of making exhibitions that teach and explain science and the history of science, we rather want to engage the audience to reflect. Not because we don’t believe in the importance of learning about science and its history. But because we believe learning is done much better by other means—in teaching laboratories, by reading books, or through the internet—than by means of exhibitions. What the exhibition medium is good at, is to engage people’s aesthetic sensibilities. By whetting the appetite of the senses, exhibitions can evoke a more subjective, personal-based and thereby deeper reflection about science, its history and its future.

Back to the fourth theme (the lilac one) about today’s metabolic research. Like a growing number of museums—but not necessarily the same museums who think in terms of art installations—we believe that exhibition making has to be built on participation. Of course, museum professionals take a lot of pride in trying to produce perfectly researched and perfectly designed exhibitions (and we at Medical Museion are no exception). Yet, we must realize that such pride in perfection does not necessarily result in engaged visitors.

And for that reason, some museums around the world have begun to ask their visitors and peers to contribute more actively to the museum functions. In analogy to social web media, some museums are now thinking in terms of the ‘participatory museum’ (‘museum 2.0’).

With respect to collections, the idea of a participatory museum is not a particularly new one. For example, our museum here in Copenhagen has been participatory since its foundation in 1907, in the sense that most objects in our rich collections have been donated by medical doctors. Also for ‘The Chemistry of Life’ we have collected from scientists and medical device companies.

With respect to exhibitions, however, few science museums have so far thought these in terms of participation. But this is about change. ’The Chemistry of Life’ is an experiment in participatory exhibition making. 5208427115_6bb07abd80_mLike software, which is never really finished, but is improved by the responses from the customers, we have thought it—especially the fourth chapter on ‘Molecular Metabolism—as a ‘beta version’.

By labeling it ‘beta’ we are inviting all faculty, technical staff and students at the University of Copenhagen to help us developing ‘The Chemistry of Life’. Instead of us telling you what is going on in metabolic research, we want you to educate us. For example, we will invite scientists, who have been part of the development of the last decades of metabolic research to a seminar, where we will ask them to tell us what they think are the most important idas, events and people in the history of the field. They may not agree among themselves, but we will nevertheless be more knowledgeable after the seminar.

We are also planning an ‘object’-day, where we invite scientists and medical doctors from the entire region to bring images of their favourite objects, or (even better) bring in the objects themselves. The result should hopefully be that, at the official opening of the Center for Basic Metabolic Research in the spring, we can show a revised version of ‘The Chemistry of Life’, especially a much more interesting and thought-provoking fourth theme.

The notion of ‘beta’ also indicates how Medical Museion will work together with the Center in the years to come. We are right now making plans for a series of exhibitions about diabetes, obesity and the new metabolic syndrome—to be shown both in Denmark and abroad, both to professionals and to the general public—and we very much want to do this in close co-operation with scientists and students here at the Faculty.

Before I give the word back to the Dean, I want to express my gratitude to the individuals, institutions and companies, who have made this exhibition possible:

  • Arne Astrup, Faculty of Life Sciences, University of Copenhagen
  • Lene Berlick, Illumina, Little Chesterford
  • Jan Fahrenkrug, Bispebjerg Hospital, Copenhagen
  • Pia Gåsland, Agilent Technologies, Hørsholm

  • Thue Schwartz, Faculty of Health Science, University of Copenhagen
  • Anna Smith, The Wellcome Collection, London
  • Mao Tanabe, Kanehisa Laboratory, Kyoto

and to the Novo Nordisk Foundation for its generous economic support.

And finally the exhibition team. If this was a scientific article, the team would be presented somewhat like this:

Speaking for all of us: I hope you will enjoy this appetizer to a future co-operative science communication programme here at the Faculty which shall engage both scientists and the public in what has been going on in metabolic research in the past, what is going on today, and what we might expect from the future.

Building new museums

When a new museum is established, it is formed both by ideas of what the role of the medical history museum in society is, and by the context out of which that specific museum comes. The challenge of building new museums was approached from three very different angles at the Copenhagen conference in September.

Kerstin Hulter Åsberg shared her vision of exhibiting the contemporary part of the history of medical sciences in the research centers where it happened and is happening. As it is the researchers and students who are at the same time the audience for the historical exhibitions and the makers of the future of medical science, they should be involved in the making of the museum from the very beginning. Read Kerstin’s full abstract here.

Wendy Atkinson expressed that for her the mission of the new health museum in Lyon she is working on is to demystify the technical side of medicine and focus on the contact between people through aspects of care and healing. Read Wendy’s full abstract here.

Robert Martensen addressed the issue of how to chose what to collect from the enormous corpus of stuff produced in the field of contemporary medical science. He suggested that the challenge of making these collected objects aesthetically appealing to an audience of grown-up academics and scientists might often be solved through displaying them in interesting contexts. Read Robert’s full abstract here.

The discussion afterwards included comments from Thomas Söderqvist, Danny Birchall, Judy Chelnik, Karen Ingham and Silvia Casini.

Telling stories about medical instruments

“How do we display artifacts which are neither sexy nor beautiful?” asked Yves Thomas in his presentation at last month’s conference in Copenhagen.

His own answer to the question was to bring a human dimension to these objects by adding virtual elements such as interviews with the researchers or video clips of the object in use. Read Yves’ full abstract here.

Nurin Veis addressed much the same issue in her talk, focusing on changing our idea about what is aesthetically pleasing instead of trying to sex-up the object. Considering the physical nature of the visitor’s presence in the museum space, we should use that space in a theatrical way to give a full experience of the objects in a historical and scientific context.

By asking the visitors to use their bodies in ways they don’t usually do in a museum, and by providing the objects with a broader context, we can change the visitor’s views on which objects are boring and which are beautiful. Read Nurin’s full abstract here.

The following discussion included comments from Morten Skydsgaard, Danny Birchall, Kim Sawchuk, Judy Chelnick, Sniff Andersen Nexø, Yin Chung Au, John Durant and Thomas Söderqvist.

Historical medical artefacts online

Last autumn I wrote about Donald Blaufox’s online collection of historical medical artefacts (MoHMA):

Nicely and competently curated and beautifully represented in images, the MoHMA website is yet another example of how important private collectors have been, and still are, for the preservation and communication of the material medical heritage.

Dr. Blaufox has now reviewed the site, record by record, improved the texts and replaced and added a lot of images. A labour of love.

Using our collections to put current trends in microscopy in perspective

1lunch time

One of our basic aims here at Medical Museion is to put current trends in biomedicine in a longer historical perspective. Last Friday, we got yet another opportunity for doing this, when the new Core Facility for Integrated Microscopy at the Faculty of Health Sciences opened together with an international research symposium on the state-of-the-art of microscopy.

1mmm interestingIn the hallway outside the symposium room, we displayed a selection of six of our most beautiful old microscopes that represent the development from early simple single lenses to end of the 19th century compound microscopes. The aim was to make the symposium participants better appreciate the beauty of early microscopes and the craftsmanship that has gone into constructing them.

During the lunch break, I had a chat with Peter Evennett, who has edited the English version of Harald Moe’s classical The Story of the Microscope together with Chris Hammond. Peter and Chris, who are members of the Royal Microscopical Society’s outreach and education committee, has helped us select the displayed items from our large collection of microscopes and write the showcase texts for the exhibition, which was designed and put together by Bente and Ion.

1magnifying glassThe oldest microscope (or rather replica of a microscope) selected is actually only a lens in a brass fitting, made in 1670 by Anthony van Leuwenhoek of Delft, who for the first time ever was able to clearly observe life on an incredibly small scale. Holding the lens at a slant towards the light, he was able to see living bacteria and wriggling, human sperm cells. It was the beginning of a whole new era for science.

1beaglemikroskopPeter went on to tell me how early microscopes weren’t used for science, as I thought, but were a kind of intellectual hobby and prestige objects for wealthy gentlemen. Consequently many of the microscopes from this period are quite charming and exquisite. It wasn’t until the 1830s — when the wine merchant J. J. Lister was able to produce objectives that minimised the colour fringing — that the microscope was seriously introduced into science. And so in 1839 a group of scientists got together to propose a toast to the instrument and to found the Royal Microscopical Society.

On display was also a modern single lens microscope from 1848, just like the one Darwin brought with him on the Beagle. The newest microscopes in the exhibition were compound microscopes from the end of the 19th century. They had a double lens system, with an objective lens that projected the image from the sample up through the tube to the eye lens, which worked as a magnifying glass. The light was redirected from a window or an oil lamp via a small built-in mirror, to hit the sample from below and carry the image up the tube, to the pupil of the scientist’s eye.

And then Peter’s efforts to educate me became technical …

Though it was by means of light that the microscope functioned, light was also the factor setting the limit for how detailed the samples could be shown. Opposed to what many people think, the basic principle in microscopy is not magnification, but  resolution. In the 1860s and 1870s, the German physician Ernst Abbe (co-owner of the Carl Zeiss AG, the famous microscope producer) discovered that the smallest distance you can have between two things before the images of them merge — and thereby determining how detailed a picture you can see in a microscope — is limited by three factors:  1) the angle of the light entering the microscope, 2) the substance through which the light has to pass, and 3) the wavelength of the light.

Of these three limiting factors the last is now being contested by using electrons with a wavelength 100.000 times smaller than visible light. But, as Peter puts it, that’s using tricks.

Can you love plastics?

Is a mass produced plastic chair just as good as an old, handmade wooden one? Yesterday Susan Lambert, Head of the Museum of Design in Plastics in Bournemouth, and professor of art history Marcia Pointon visited us to look through our collection of artifacts made of plastic. They are planning a new research project focusing on our relationship with plastics in a hospital context, and would like to have Medical Museion as one of their research partners.

              1 susan og marcia

Ion showed us plastic dentures from the 1860s, a very realistic plastic arm with painted finger nails, and colourful plastic leg pads for children. Even though museums in general look down on plastics as an inauthentic material, we actually found a lot of objects in the collections, which partly or totally consist of some sort of plastic. The two plastic-lovers enjoyed the tour, even though Susan was a bit frustrated because of not being able to touch the displayed objects. The wonderful thing about plastics is that it can look exactly like any other material. But as Susan put it;”Once you touch, you know”.

Plastics are discount: Plastic is also an interesting material because it is highly used, but not very highly thought of. Unconsciously a lot of people today think of plastics as a discount material, as the fast, cheap unnatural solution. The wide range of functions that makes plastics so usable is the same feature that alienates it from us. One can make anything out of plastic, which means that plastic in itself is invisible and without identity. Plastic is, what it is made into. Alone it is formless, it is nothing. It is hard to develop a relationship to an thing made out of plastics, when one knows that there are a million plastic objects out there exactly like it.

  1 benskinner i farver 1 plastikarm

Plastics are clean:  already from the mid 19th century the first synthetic materials began to appear and in the beginning of the 20th century, Bakelite (phenol formaldehyde), which was used for electric apparatus like telephones and plugs, was invented. It was not until the 1960s that plastics became the most common material to use in almost all areas of human life. Susan and Marcia are focusing on plastics in a hospital context, because in hospitals one will find both plastic object of everyday use and highly specialized hospital objects in the same material. At the same time the many single use objects exemplifies the good aspects of plastic products, like good hygiene, and environmentally bad aspects like waste problems.
