Eric Robinson, consultant to Sir Colin Wilson, our architect, and a former University College London lecturer and urban geologist produced a free BL booklet several years ago entitled “A Geology of the British Library” in which he drew our attention to the beautiful geological and paleontological features of the stone, marble and building materials used on both the interior and exterior of the library building at St. Pancras.

A walk around the site or formal tour will offer the opportunity to look at the fascinating fossils and geological patterns visible in the marble, on the floors and in the public areas:

Key features and types of stone to be found, include:

• New red sand stone from the Permian period around the piazza and main entrance gate.
• Handmade red bricks that characterise the building and courtyard, are made from southern England clay, high in alumina and at high kiln temperatures with controlled oxygen to create the impressive red colour.
• Fossilized sea sponges can be seen in the French Hauterville limestone located outside the conference centre.
• Creamy white Portland stone squares contrast with the darker Purbeck limestone slabs that can be found on the upper ground floor around the reader registration entrance and 3D library model. This Purbeck limestone,  on closer examination, reveals dark fossilized bivalve sea shells and fresh water molluscs.
• Antony Gormley’s Planets installation in the piazza, consisting of 8 similar sized rounded glacial boulders from Malmo, Southern Sweden, reflecting the impact of the ice ages on their surfaces over the last 2 million years.

We’ve been blogging and tweeting a lot about the historical inventions in the GREATforImagination campaign, with links to the key patents involved. Unfortunately, most British patents from before 1895 aren’t available free online and can only be seen if you come to our building at St Pancras. We’ll be making full blog posts about some of these, to give you some more detailed information than can fit into a Tweet or the Instagram post.

Not every invention is made by people who see a problem and set out to find a solution to it. Curiosity-driven science can produce useful inventions that the scientists involved never anticipated. A classic example of this took place in 1856, when William Perkin tried to make an artificial anti-malarial drug, and instead discovered what would become the first totally human-created molecule to become the centre of a profitable business.

The eighteen-year-old Perkin was a student of the chemist August Wilhelm von Hofmann at the Royal College of Chemistry in London (eventually merged into what would become Imperial College). Hofmann had speculated to Perkin that on the basis of the atomic formulas then assigned to the chemicals, it would be possible to create the drug quinine by somehow combining two molecules of napthylamine with one of water. Perkin decided to try to synthesise quinine by oxidising allyltoluidine with dichromate. It is now known that the complex structures of organic molecules make such a naïve approach based purely on atomic formulas useless. When Perkin failed, he decided to try oxidising aniline with dichromate (it was subsequently discovered that the aniline he used was contaminated with toluidine, with mauveine being created by the oxidation of both together), and discovered that the product obtained was a useful dye. Mauveine, as it became known, was the first cheap and stable purple dye, and when Perkin commercialised it a colour that had been traditionally associated with the richest in society became accessible to all. It was the first of the so-called azo dyes, which were among the first products of the modern chemical industry.

Perkin patented his dye and persuaded his relatives to fund him in creating a factory, near Greenford in west London. He continued to work in chemistry, discovering the “Perkin reaction” to make cinnamic acid from acetic anhydride and benzaldehyde, and developing a way to commercially synthesise the natural dye alizarin (from the madder plant) from coal tar. Unfortunately, a rival German team simultaneously developed the same process and patented it one day earlier! Perkin’s lasting fame can be gauged by the fact that the Perkin Medal, the most important American prize for organic chemistry, and Perkin Transactions, for many years the British Royal Society of Chemistry’s main scholarly journal on organic chemistry, were both named after him.

Perkin’s mauveine is a mixture of up to twelve different compounds containing N-phenylphenazinium ring systems with additional amine and sometimes methyl groups. The structures of the most important two were not clearly discovered until 1994, because an incorrect structure of unclear origin had been repeatedly cited in the literature and assumed to be right. They are seen in the diagram, with the group "R" being a hydrogen atom in one of them, and a methyl (CH₃) group in the other.

The Patent Office Library was one of the British Library’s founding collections and we are currently incorporating its books into the Library’s main collection. Recently I came across a forgotten treasure, a large coloured lithograph (24” x 52”) showing in great detail the interior of a Victorian battleship. The ship was HMS Royal Albert , the largest first rate sail battleship ever built for the Royal Navy. At 5000 tons displacement and with 131 guns it greatly outclassed HMS Victory’s 3500 tons and 104 guns. The Royal Albert was laid down in 1844 in Woolwich Dockyard at the very end of the Navy’s tradition of wooden construction. This also marked the final years of the Thames as the centre of the ship building industry. The invention of screw propulsion had just made one of the great leaps forward in marine technology and so the Royal Albert was adapted in 1852 while still on the stocks to take a 500hp auxiliary steam engine and a propeller. She sailed on to be the flagship of the Mediterranean fleet and saw action in the Crimean War. However the dockyard modifications proved faulty, the propeller shaft leaked, and the ship was broken up in 1884.

Section of a first class, first rate line of battle ship of 131 guns with screw propeller and auxiliary steam power. To Captain….Sir Baldwin Walker, Surveyor of the Navy. This print is with permission respectfully dedicated by his obliged and obedient servant Charles Lewis Pickering. Paris and New York. Goupil & Vibert. 1852

The library’s fold out collection item, a cutaway view, was a novelty for its time and is a forerunner of those much loved illustrations in the Eagle comic of the 1950s and 60s. The cutaway shows the layout of masts, engines, guns, store rooms and all the equipment of a warship. The particular charm of this piece is the lively human detail that is so often missing from ship paintings, a gun crew at their mess table, sailors in their hammocks, the marine band practicing, blacksmiths at work and the Captain’s wife in full crinoline standing in their cabin.  

Why this unusually large print by the artist Charles Lewis Pickering was published is not known but its quality suggests that it was made to commemorate a significant event for the Royal Navy, perhaps the ceremonial launching of the Royal Albert by the Queen. Further research on the artist drew a blank until I checked the British Newspaper Archive which holds millions of digitised newspaper pages from the British Library's collection. There I found an account from the Bury Post of July 1853 which shows how desperate Charles Pickering was to market his production:

“Impudent imposter – Last week a person waited upon Earl Jermyn, at his town residence, and presenting a card with the name “ Mr Charles Lewis Pickering” represented himself as brother-in-law to the Editor of this paper, and solicited his Lordship’s patronage for an engraving of a screw steamer, dedicated to the Surveyor of the Navy. The Noble Lord, deceived by this representation and by the signatures of Members of both Houses of Parliament and other gentlemen with whom he was acquainted was induced to add his subscription and his guinea but afterwards discovered that the trick had been practised upon another Member by precisely the same tale of connection with the Editor of a Paper in the town represented by that Member. We hope it will not be inferred from the occurrence that newspaper Editors are especially addicted to solicitations of the patronage of their representatives.”

The middle of the nineteenth century saw an arms race in ship design. In 1859 HMS Warrior was laid down as the Navy’s first all metal hull and two years later HMS Prince Albert was the first ship to mount rotating gun turrets and lack mainsails. In a decade, warships had progressed from the wooden walls that Nelson would have recognised to something close to a modern warship’s silhouette. And for a contemporary contrast, the Queen Elizabeth, the largest capital ship ever built for the Royal Navy, sailed on its sea trials recently, powered by 100,000 hp electric motors and displacing 70,000 tonnes.

To publicise the upcoming event: Anne McLaren: Science, Ethics and the Archive, to be held at the British Library on 20 July, 6.30-8.00 pm, we present a guest-post by Professor Marilyn Monk, UCL Emeritus Professor of Molecular Embryology, with her personal recollections of Anne McLaren.

       
It is a great honour to have this opportunity to give my own personal tribute to Anne McLaren. Anne was my role model and my mentor over so many years. Not only in my scientific life - although her influence here was huge - but she was such a tower of strength and support for me over many difficult times. ‘Water under the bridge Marilyn. Water under the bridge’, she would say, encouraging me to move on.

I worked closely with Anne in her Medical Research Council Mammalian Development Unit for 18 years from 1974 to 1992 and I remained in contact with her thereafter. I would often email or phone Anne – ‘what do you think of this Anne?’ – questions about science, about life, about new ideas. And she would always respond with words of wisdom and support.

Right from the beginning Anne accepted me unconditionally. My first encounter with Anne was my phone call to her in Edinburgh in 1974. At that time, Anne was in Animal Genetics at Kings Buildings in Edinburgh and I was in the Molecular Biology Department working on DNA replication and repair in bacteria and on slime mould aggregation. But, in 1974, our MRC unit in Molecular Biology in Edinburgh closed with the retirement of our director, Bill Hayes. The MRC told me that I could relocate to another MRC unit that interested me and that would have me. I visited many MRC units and talked to various people who were encouraging but nothing seemed to be right for the interests and expertise in research I had at the time. Then Harry Harris at the Galton Laboratory suggested I contact Anne McLaren as she was just about to move from Edinburgh to London to start up a new MRC Mammalian Development Unit at the Galton. I knew nothing at all about development - let alone mammalian development. A move to mice and their embryos would be a huge leap both intellectually and technically.

In any case, I plucked up courage to phone Anne in Edinburgh in 1974. I remember everything about that moment when I phoned Anne because I was holding onto my last hopes of continuing as a scientist. I introduced myself, told her my problems, and asked her if she would consider taking me on in her new MRC Unit in London. I told her I knew nothing about mice – I had only worked with bacteria, viruses and amoebae. She said, ‘Yes of course you can join me. You must!’ I was flabbergasted. So overjoyed I could not speak. She did not even know me. She didn’t ask to meet me. But she had no reservations. She’d give me a chance. But this says it all about Anne - a tower of strength and support, particularly for women scientists (in my experience, it can still be difficult, even today to be a woman in science).

But as well as being a tower of strength, Anne was patient, tolerant, allowing, and very wise. And of course - very intelligent. I would prefer to talk about science and life and new ideas with Anne than anyone else I know. And Anne was a great listener. She always liked my ‘What if’ ideas and 'Why' questions. She thought that some of them were 'whacky' (her word) but always interesting.

Another great quality of Anne’s was her wicked sense of humour and sense of fun. Over the years, she would only have to raise one eyebrow in my direction over some happening, or strange remark from an unsuspecting visitor, and it would be difficult for me not to collapse in giggles. I always knew what she meant by the raised eyebrow. I felt privileged to be a secret accomplice to the raised eyebrow.

I know there are so many others who will have had the same wonderful experiences of Anne and will be feeling the way that I do. In the days and weeks after Anne died, so many people shared that they had just been in touch with her about this or that – about meeting soon for a meal and a talk about science and about life, or asking her advice on various issues, or arranging some new initiative. I have realised that Anne was looking after all of us pretty much all of the time. She made each one of us feel special.

Her energy and engagement with life and people was phenomenal. In addition she had extra-ordinary self-discipline and I had a lot to learn from her here. I never once saw Anne nod off in a seminar. She listened carefully to everything everyone said and her responses were always measured, incisive and invariably ‘spot on’. She never said a bad word about anybody that I can remember. She never complained.

When I joined Anne’s Unit, I was already a molecular biologist of some 15 years. But as such, I was used to working with millions of cells, bacteria or amoeba. We used to call it bucket biochemistry. The huge challenge was to bring molecular biology to the few cells of the embryo and even to the single cell. And we did it. I guess the hallmark of my research with Anne was to make the molecular techniques a million times more sensitive so we could look at specific enzyme activity, specific gene expression, and specific gene mutation or modification in just a few cells, and even a single cell, of the embryo. Once these single-cell molecular technologies were established, we could apply them to different developmental and biological questions and many insights into mammalian development followed during the years I was at the Galton. We began with establishing the cycle of X chromosome activation and inactivation as a model for gene expression and its regulation in early development. From there, we made many new discoveries such as the late origin of the germ line (anti Weissman doctrine). differential methylation of the active and inactive X chromosomes (beginning of mechanisms of epigenetics), imprinting and transgenerational inheritance of acquired characteristics (Lamarkian inheritance) and the discovery of methylation erasure in early development and again in the germ line thus bringing development back to tabula rasa - totipotency. Clinically we applied our single cell molecular biology to pioneering experiments for preimplantation diagnosis of genetic disease. My colleagues and co-workers during these years in Anne's Mammalian Development Unit were Mary Harper, Asangla Ao, Andrew McMahon, Mandy Fosten, Susan Lindsay, Maurizio Zuccotti, Mark Grant, Michael Boubelik.and Cathy Holding. Anne always gave me a completely free rein and encouraged me in whatever I wanted to do. I still miss her.
