Call for more blue plaques to mark scientists’ connections to London buildings

Picture: English Heritage

Today English Heritage unveils a new blue plaque to the theoretical physicist and Nobel Laureate Abdus Salam (1926-1996), with an appeal for more nominations for scientists to increase their representation in the London scheme. As a historian of science sitting on their Blue Plaque panel, I am delighted to support this call.

Scientists and natural philosophers account for around 15% of the more than 950 blue plaques in London. Some of these will be found categorised under medicine or engineering but the scheme lists just 66 plaques online under the category of science, in contrast to 102 as fine arts, 171 politics and 213 literature. These numbers are a product of the scheme’s earlier history, under the Society of Arts, London County Council and Greater London Council, as well as of broader cultural assumptions about who and what should receive such marks of public esteem.

The contributors to science honoured by blue plaques include key figures of the 17th-century Royal Society, Isaac Newton and Christopher Wren, as well as household names such as Charles Darwin and Alan Turing. But our understanding of science suffers if it encourages an assumption that its progress has been due only to a few geniuses, usually white and male, and often seen as working in isolation from society.

Happily, this scheme also recognises a whole range of other contributors and contributions. One plaque marks the Holborn site of the shop and workshop of the watchmaker Thomas Earnshaw, another the home of the Scottish plant collector and ‘tea thief’ Robert Fortune, and in Hackney we find a plaque to the zoologist Philip Gosse. The new plaque to Salam reminds us that not all eminent contributors to science in London were white or born in the west.

There are also, especially after recent calls for nominations, several plaques marking women scientists. These include the increasingly celebrated figures of Ada Lovelace and Rosalind Franklin but also a number whose plaques should help them to be more widely recognised, such as the botanists Agnes Arber and Helen Gwyenne-Vaughan and the electrical engineer and physicist Hertha Ayrton.

One of the distinctive features of the scheme is that a building associated with a nominated figure should still survive. While this limits who can be put forward, it has the benefit of encouraging us to think about these individuals in context – not just as those who contributed ideas and information to their scientific field, but as people who lived and worked, loved, laughed and prayed, across London’s boroughs. Science is a human endeavour that is not, and never has been, isolated from place.

The biases of building survival, as well as the wealth and connections that are often prerequisites for success, mean that many blue plaques are found on substantial buildings in places like Westminster, Kensington and Chelsea. But we find that other locations and a wide variety of stories are revealed by these combined markers of place and people.

Abdus Salam’s plaque is on a red-brick Edwardian house in Putney, his London base from 1957 until his death in 1996. While the wording of the plaque tells of his international fame and role in championing science in developing countries, the location is residential, a home where he studied and wrote, and listened to music and Quranic verses on his record player.

The very first plaque to a scientific figure, unveiled by the Society of Arts in 1876, is in Marylebone. It celebrates Michael Faraday (1791-1867), known for his discoveries in electromagnetism at the Royal Institution. However, the plaque records that he was ‘Apprentice here’, for the building is where he worked not as a chemist but as a bookbinder. His apprenticeship moved him from Newington Butts in Surrey to a building from which he could attend scientific lectures.

In Hackney, though sadly not currently visible from the street, there is a plaque to Joseph Priestley (1733-1804). A chemist, best known for his discovery of gases, including Oxygen, Priestley was also a teacher and preacher. His plaque, calling him ‘Scientist, Philosopher and Theologian’, tells us that this was the site of the Gravel Pit Meeting, a nonconformist religious congregation to which Priestley was minster.

While Priestley’s is one of the wordier plaques, it is another man of science who has one of the most evocative. This is Luke Howard (1722-1864), described as ‘Namer of Clouds’. He was the amateur meteorologist who proposed the classification and Latin names for clouds. He was also a manufacturing chemist of means, whose plaque is at 7 Bruce Grove in Tottenham. Now owned by developers it is currently vacant and at risk, with campaigners hoping to save it from further deterioration. As the site of Tottenham’s only blue plaque, and a Grade II listed building, it would be a tragedy to lose Howard’s former home.

English Heritage, and the Blue Plaque panel, rely on the public to make proposals for plaques such as these. They particularly welcome those that help reveal the significant stories that link scientists and London’s buildings.

Upcoming history of astronomy talk

Update: You can now watch the recording of the talk via the link below.

Edinburgh to Hawai’i: the short astronomical career of John Walter Nichol

20 November 2020, 19:30-21:00 – Free

The Astronomical Society of Edinburgh (via Zoom for members; visitors can watch live via their YouTube channel): further details here.

J..W. Nichol as depicted by Lieutenant E.J.W. Noble in ‘The Life & Adventures of Station B’, digitised by Cambridge Digital Library.

The name John Walter Nichol enters the history of astronomy for his participation as an observer in one of the British expeditions to observe the transit of Venus in 1874. He was said to have been an assistant at the Royal Observatory, Edinburgh, but little else has been added; he was just one of the small army of observers mobilised that year. He is, however, brought to life in the caricatures that another member of his expeditionary team produced to record their ‘Life and Adventures’ on expedition. These prompted me to find out more: what brought this Edinburgh native to astronomy and to Hawai’i, and where did he go next?

Talks on astronomy, mathematics and voyages of exploration – available to view

Book review: Writing about women’s lives in science

An edited version of this book review appeared in the latest issue of British Journal for the History of Science (vol. 49, 2016, pp. 529-30).

 

Govoni, Paola, and Franceschi, Zelda Alice (eds.), Writing about Lives in Science: (Auto)Biography, Gender, and Genre. Goettingen: V&R Unipress, 2015. Pp. 287. ISBN. 978-3-8471-0263-2. €44.99 (hardback).

Biography within the history of science has repeatedly been rescued, revived and reconsidered: from Thomas Hankins’s 1979 ‘Defense of Biography’, to the essays in Telling Lives in Science (1996, eds. Michael Shortland and Richard Yeo), the 2002 workshop that led to The History and Poetics of Scientific Biography (2006, ed. Thomas Söderqvist), the 2006 ‘Focus’ section in Isis and now this collection. Many of those who have written biographies have been reflexive about their motivations and their version of their subject’s life and character. Richard Westfall, for example, produced some fascinating reflections for the 1985 collection Introspection in Biography, showing the wisdom of B.J.T. Dobbs’s comment that Newton is “something of a Rorschach inkblot test” for historians (Isis 85 (1994), 516). Those academic biographies of major figures have, after all, still been produced and, as Margaret Rossiter and Pnina G. Abir-Am led the way from the 1980s onward, so too have collections and considerations of lives of women scientists.

Searching for Copley Medals – seen one?

I am currently revising a paper on the early history of the Royal Society’s Copley Medal for publication. I told part of this story in a post one the H Word Guardian Science blog. Although it is tangential to my main story, because I am particularly interested in the materiality of the medal scheme I would like to trace extant Copley Medals and would be grateful for any help readers can give me.

I am looking particularly for copies of the medal that were made from the original die that was engraved by John Sigismund Tanner at the Royal Mint (his signature ‘T’ is visible on Athena/Minerva’s plinth). One of the very earliest is that given to John Belchier (below, now at the British Museum) – it was awarded in 1737 but he only received the medal after copies were first struck in 1742.

Eighteenth-century eclipse maps by Halley and Whiston

Earlier this month I published a post at the H Word on ‘Halley’s Eclipse’ of 1715. It has been associated with Edmond Halley because, using the best theory and data then available, he made impressively accurate predictions of its timing and path, publicised through a broadsheet map and the Royal Society. As I explain in the post, however, he was not the only one to do so: London was a competitive market for scientific publications and authority.

This post is an appendix, where I can show more of the eclipse maps published than I could on the Guardian’s website. I should add, too, that these were not the first predictions or maps of solar eclipses, and that there were earlier German, Dutch and French maps.

Here, however, is Halley’s first map, from Eclipse Maps, which was published in advance of the event, encouraging observation. It is titled “A Description of the Passage of the Shadow of the Moon over England, In the Total Eclipse of the Sun, on the 22d Day of April 1715 in the Morning”. I am not sure where the original is kept, but it may be the same as that reproduced in black and white in Jay Pasachoff’s article on Halley’s eclipse maps, which is from the Houghton Library. The full text, which is not high enough resolution to read here, has been transcribed by Pasachoff.

Halley seems to have produced more than one edition of the map before 22 April 1715 (O.S. – the anniversary was celebrated on 3 May N.S.), and also one after the event, showing the path as corrected by observations. This copy of his “A Description of the Passage of the Shadow of the Moon over England as it was Observed in the late Total Eclipse of the Sun April 22d, 1715 Manè” is from the Institute of Astronomy, University of Cambridge, where you can see some superbly high-resolution images.

Halley came back to his winning formula when another eclipse rolled along. His map, published in 1723 (annotated November 17123 here), showed both the recomputed path of the 1715 eclipse and the predicted path of 11 May 1724. This image is from the Houghton Library’s Tumblr, where it is available in higher resolution. The text declares that the first map “has had the desired effect” in encouraging observation and uses this one to demonstrate that his predictions had been pretty good in 1715 and were worth acting on again.

However, as my post discussed, William Whiston was also in the business of predicting eclipses and selling scientific paraphernalia.  Like Halley, he was making predictions based on John Flamsteed’s observations at the Royal Observatory and corrected with Isaac Newton’s theory, and encouraging observations. Whiston made comparison of his observations with Halley’s and his  two eclipse-predicting broadsheets are again from the Cambridge Institute of Astronomy’s Library here and here.

The one I think is the earlier from Whiston was dated 2 April 1715 and titled “A Compleat Account of the great Eclipse of the Sun which will happen Apr. 22 in the Morning”. It is much more text-heavy and technical in content, and the map is a celestial one, showing the positions of the heavenly bodies rather than the path of the shadow on Earth.

A second broadsheet by Whiston did show the Sun’s shadow on the Earth, but from a global point of view. The title too emphasised that this was not just an English matter: “A Calculation of the Great Eclipse of the Run, April 22d 1715 in ye Morning, from Mr Flamsteed’s Tables; as corrected according to Sr Isaac Newton’s Theory of ye Moon in ye Astronomical Lectures; with its Construction for London Rome and Stockholme”. It also advertised an instrument that could be bought from Whiston.

John Westfall and William Sheehan’s new book on observing eclipses, transits and occultations, indicates the Whiston and Halley’s estimates varied by about 25 miles, which perhaps puts the more triumphant claims of accuracy in perspective. I think (correct me below if I am wrong) that Halley’s prediction was the more accurate, but there was an element of luck involved. Above all, his map, showing geographical detail of England beneath the path of totality, was much more persuasive and appealing – this is the main reason that the 1715 eclipse became ‘Halley’s’.

Whiston had learned the importance of the image by 1724. His “The Transit of the Total Shadow of the Moon” this time showed familiar coastal outlines, although again other parts of Europe were included: Paris would be a better observing site than London this time. This version is from the Science & Society Picture Library and belongs to the Royal Astronomical Society.

And so the maps continued: there are many to explore in the wonderful albums at Eclipse Maps. It was a flourishing business come eclipses in the 1730s and beyond, especially that of 1764, as many publishers jumped on the opportunity that Halley and Whiston had spotted in 1715. So too, of course, had the person that links all the images shown here: the engraver and cartographer John Senex, who deserves a much fuller biography on Wikipedia than this!

 

Real, replica, fake or fiction?

When we allowed a Steampunk ‘intervention’ into Flamsteed House and the Time and Longitude Gallery at the Royal Observatory Greenwich last year, in the exhibition Longitude Punk’d, reactions were varied. Many were really positive about bringing some imagination and artistry in to explore the themes, objects and spaces and we undoubtedly attracted at least a few visitors who might not otherwise have gone.

There were, however, more than a few staff and visitors who were annoyed that we were mixing fact and fiction and taking away the authoritative voice of the Museum. How would people learn anything? How would they know what was real history and which were the real objects? Either proving or entirely dismissing their point, most visitors, particularly tourists there for a photograph on the prime meridian, probably didn’t even realise that they were not seeing a straight forward exhibition.

What those who worried about ‘reality’ perhaps don’t fully appreciate is the extent to which fictions and fakes are always a part of museum displays. It is the joy of something like this exhibition – or the really wonderful Stranger than Fiction exhibition at the Science Museum – that they force you to think harder about what we’re presented with and how we too blindly trust the authority and ‘reality’ of certain modes of presentation.

For me, this photograph I took in the Royal Observatory’s Octagon Room during Longitude Punk’d nicely brings out some of what I mean.

While, even for the non-too eagle-eyed, it is clear that the dress in the centre, created for Longitude Punk’d, is not 18th century, for most visitors it might appear that this is a modern piece, with historical nods, simply dropped into a 17th-century space. It is a fiction dropped into history. But things are not what they seem.

Firstly, of course, we can note the museological trappings that make this space very different to the one that John Flamsteed knew. There are barriers, electric lights and museum labels, also a smooth, light wood floor. But what of those paintings? The instruments? The clocks and panelling?

A right old mix-up is the answer. Artfully arranged to evoke the 1676 engraving of the room by Francis Place:

Prospectus intra Cameram Stellatam [View inside the Star Room] (Photo: National Maritime Museum)

What we have is a mixture of ‘original’ pieces, later historic objects, 20th-century replicas and 21st-century recreations. The room, much altered over the years, has been completely recreated. The engraving doesn’t give us much information on the nature of the panelling, but restoration work on the rooms downstairs suggested that a fake wood effect had – at least there – been an early wall treatment. Thus an original ‘fake’ effect has been ‘authentically’ recreated, possibly in the wrong space.

The astronomical quadrant, on the left, is a ‘real’ historic object, but some 75 years too late for this set-up. The telescope on the right (out of sight in my picture, but recreating the one in the engraving) is pure prop, without lenses. It used to offer those who bothered to take a look a view of a faded slide of Pluto (the cartoon dog). Now, after much effort of the sort that only those acquainted with the pace of change in large museums will appreciate, it has a picture of Saturn (the planet), fuzzed and chromatically distorted to give some sort of idea of what it was like looking through an early telescope. Obviously Saturn ain’t really visible, through the windows, in the daylight.

What of the paintings? Well, the rather splendid portrait of Charles II (left) is from 1670. I assume (correct me if I’m wrong – annoyingly the catalogue entry doesn’t give the provenance) that this has stayed at Greenwich, if not this room, throughout the centuries – it is certainly similar to the one in the engraving. However, for the purposes of this post we should note that it is nevertheless “thought to be a copy of a Lely”.

The engraving also shows us a painting of the Duke of York, later James II, who had been, perhaps significantly, Lord High Admiral until 1673. However, the one that is currently there is in fact a commissioned replica from 1984. I have no idea what happened to the (copy?) Lely of James that was originally there. Did Charles survive and not James because of an anti-Catholic Astronomer Royal (nearly all of them, I reckon, before the 20th century)? Answers below, please.

The clocks, originally by Thomas Tompion, are perhaps the most complex story of all. Again, what’s in the two images appears to match but that’s about where it stops. Famously, after Flamsteed’s death his wife Margaret sold off the books and instruments at the Observatory, fairly seeing them as private property since they had either been bought by or gifted to Flamsteed. The clocks, therefore, left the observatory.

Today, one of the clocks is back, but on the other side of the room. That is because it was altered and its original 13-foot pendulum changed so that it could be turned into a longcase clock. The clock, with the original dial fitted into an 18th-century wooden case and its mechanism on display in a late 20th-century glass case, is a completely different beast. Next to it is a (wonderful) interloper: a Tompion longcase, which only moved to the Observatory in 2010.

What you can see in the top picture is two replica dials (although the one on the far right is a replica of a sideral clock that, although it was included in the Place drawing, seems never to have actually been installed at the Observatory: a replica of a fiction, therefore) and a reconstruction. The reconstruction, a “tribute” to Tompion by a horology student at West Dean College, has a transparent dial so that the extraordinary pendulum, with a backwards-and-forwards rather than side-to-side motion, can be admired. Excitingly, though, for seekers of ‘reality’, the clock’s positioning was “made possible as many of the original holes for the mount fittings are still visible.”

There we have it. The most original thing in the room are some holes behind the skirting.

On longitude in BBC History Magazine

A piece that I wrote for BBC History Magazine, which appeared in 2014, has been made available by someone (Morgan High History Academy, anyone?) as a PDF online here. With some nice pictures, courtesy of the National Maritime Museum, and some good editing, courtesy of the magazine’s editors, it’s perhaps worth a look.
