    Re-packing UCL´s Magic Lantern Slides

    By Margaux Bricteux, on 29 July 2014

    As my time working with UCL’s lantern slides draws to a close, I thought I’d reflect on some of the things I’ve discovered over the past few weeks. (To learn what lantern slides are, and why UCL has accumulated thousands of them, click here).

    Slide EE703 – A Vreeland oscillator, 
    or just another electric circuit
    to the unaccustomed eye.

    The majority of  the slides in the UCL Science and Engineering collection are, unsurprisingly enough, about Engineering. Electrical Engineering to be precise. I must say that, having not had a single Physics lesson in the past six years, the prospect of cataloguing slide after slide of what looked like identical electric circuits was not exactly my cup of academic tea. But I soon learnt that there is a lot more to ElecEng (as it is apparently abbreviated) than alternators, resonators, oscillators and commutators. In particular, I became interested in UCL’s very own Sir John  Ambrose Fleming, founder of England’s first University Department of Electrical Technology, inventor of the thermionic valve and Pender Professor at UCL for three decades.

    The UCL Grant Museum and the Science and Engineering Collections currently have several thousand magic lantern slides that relate to subjects as diverse as telegraphy, astronomy or Australian coral reefs; but which for the most part have been consigned to gathering dust in splintering wooden boxes. I, however, have spent the last few weeks sorting, auditing and cleaning hundreds of these slides, and I am now rather well acquainted with these little glass squares.

    Magic lanterns were first developed in the 17th century as one of the earliest image projectors. While the device itself has evolved, the concept has remained the same: A combination of lenses and a light source are used to enlarge the images found on glass slides (each about the size of a Post-it) and project them onto a wall or screen. Magic lantern slides, hence, can be described as a kind of ancestor to the Kodachrome slides used in slide projectors, or even present-day PowerPoint slides. (more…)

    Museum Training for the World

    By Edmund Connolly, on 7 March 2014

    UCL is launching a new project with the British Council to help develop and teach new methods of Museum management. The Museum Training School opened this week and is aimed at mid-career professionals who are aspiring to be emerging leaders in the museum sector.

    The MSSL with comet Hale-Bopp

    One of the things I enjoy most about my job is that I get to work with many different departments from across UCL. I meet people from a wide range of backgrounds and get to do some pretty interesting stuff with them. And of course being a curator I get to work with collections as well, which is in my opinion the best thing about working in museums.

    In the last few months I have had the good fortune to visit the Mullard Space Science Laboratory (MSSL). A part of UCL that very few people get to see, staffed by people who are extremely passionate about their jobs, and housing a whole new collection of objects that I didn’t know existed.

    The MSSL was opened in 1967, and is the largest university space research group in the UK. Not only that but its early date marks it as one of the earliest such centres in the world, and makes it an important part of the early history of the British Space Programme, now known as the UK Space Agency (yes we really do have one of those). The lab is located near (more…)

    A week in the life of a Curator

    By Nicholas J Booth, on 18 September 2013

    People often ask me what it is I do for a job. “Well” I answer, “I’m a curator”.

    the Grant Museum.

    “Yes, but what do you actually do?”

    “I curate a collection, I help look after it”.

    “Yes but what do you ACTUALLY do all day?”

    It’s a good question, and one to which the answer is never really that simple. What I ‘actually do’ varies from week to week, and depends upon what I have to do, what I need to do, and what I have time to do. So I thought I would write a blog as a way of answering.

    Last week I made a point of recording exactly what I was up to between Monday and Friday, and tried to take a few more photos that I would normally. I should say that I did not particularly plan for this week to be one I blogged about, and I resisted the urge to book in lots of important sounding meetings. I had planned to use a stepometer during the week, to see how far I walked, but sadly couldn’t get my hands on one in time.

    So, my week…

    Ask A Curator Day

    By Nicholas J Booth, on 17 September 2013

    Ask A Curator,  18th September 2013

    Ask A Curator Day,
    18th September 2013

    On Wednesday 18th UCL Museums will be taking part in the Ask A Curator Day event on twitter. The original day was way back in 2010 and this year already has more museums signed up than ever before (525 in 34 countires at time of writing). We know that asking a question in a museum can sometimes feel intimidating , and that we curators can sometimes be hard to track down. There’s so much to do (all that cataloguing…gah!) that we aren’t always the most accessible group of people (though we really do try).  We are taking part in the day as part of our commitment to make our collections as accessible as possible.

    Ask A Curator works like this.  Anyone in the world with a twitter account can tweet a question with the #AskACurator hashtag, and it will be answered by any of the institutions taking part. If you have a specific question for us you can tweet it directly to us @UCLMuseums and one of our staff will do their best to answer you. The Grant Museum is also taking part using @GrantMuseum.

    In preparation for this I thought I would introduce you to our members of staff taking part… (more…)

    Conserve It! Part IV – Filling and Finishing Touches

    By Nicholas J Booth, on 5 July 2013

    This is the final installment of the excellent Conserve it! blog series, written by four conservation students from the Institute of Archaeology. In this post Leslie Stephens and Louise Stewart describe the last stages of the process.

    To read the full series please click on the ‘Engineering Collections’ or ‘Science Collections’ category tabs on the left hand side of this page.

    Conservation doesn’t end when all the pieces are back together. Once researched, cleaned and reassembled, the x-ray tubes will need further work. Filling gaps and preparing the tubes for storage are the final stages in the process.

    Why do conservators fill gaps in objects? Fills are usually undertaken for two reasons: aesthetics and support.  When an object has most of its pieces remaining, it is frequently the job of the conservator to make an object look as complete as possible so that visitors are aided in its visual interpretation. When the object’s original material is fragmentary, it is often difficult for visitors to understand what it would have looked like before damage. The more material is missing, the harder this job is for the conservator. There is a fine line between aiding interpretation for the visitor, and presenting an object that is too much ‘interpretation’ and not enough original material. If the conservator is not certain what the missing fragments would have looked like, they are less likely to fill that area with a ‘guess’.  When there is very little original material left, however, fills sometimes hold fragments in place. This happens especially when there is not enough original material left for the object to hold its own weight; these types of fills are considered support fills.

    Installing the Octagon Exhibition

    By Nicholas J Booth, on 6 June 2013

    Most of last week I was busy installing the new Octagon Gallery Exhibition, ‘Digital Frontiers: Smart, Connected and Participatory’, curated by Claire Ross from the UCL Centre for Digital Humanities. The exhibition features a huge range of objects, from a tweeting doorstop (the ‘sheep-pig’) to a drawer of pinned beetles, however most of the objects have come from the UCL Engineering Collections. This is one of the collections I look after, so I thought I’d talk a little bit about what goes into the process of putting together one of UCL’s Octagon exhibitions.

    The exhibition opened on Wednesday 5th June. However the first meeting happened back in September when all the curators and collections managers from the different UCL Museums and Collections get together with Claire to hear about her plans for the exhibition, and to initially brain storm about what we have in our collections that fit with the exhibition subject. This was harder for some collections than others, but happily was relatively easy for me.

    After this initial meeting Claire met all the curators individually to discuss the exhibition and view possible objects, before going away and coming up with a long list of what she wants. In the case of the Engineering Collections it was a very long list…which is great! However this also means that there was a lot of work for me, and others, to do.

    Conserve It! Part III – Reconstruction

    By Nicholas J Booth, on 24 May 2013

    This is the third installment of the Conserve it! blog series, written by a team of UCL conservation students who are working on four damaged objects from the Medical Physics Collection. Here Louise Stewart explains how they have gone about reconstructing the smashed tubes.

    Now that our background research is done and we’ve considered the various significances the objects, we come to the most time-consuming step of conservation: the actual treatment! In this case, the main portion of treatment for all four of us is the reconstruction of the glass bulbs of the various x-ray tubes.

    Conserve it! Part II – Research and Investigation

    By Nicholas J Booth, on 27 February 2013

    The second instalment of the Conserve it! blog, written by Miriam Orsini, details the research and analysis that conservators have to undertake before they even begin to work on objects. Particularly exciting for me is the photo towards the end of this post showing one of the X-Ray tubes glowing green under UV light! I had no idea they could do this…

    Probably one of the most exciting things conservators must do before they start conserving an object is researching and analysing the object itself. This is the moment when the object starts to talk to you and tells you its story. In this post we are going to share some of the pretty amazing stories which these X-Ray tubes have told us.

    We started with some preliminary research using the internet and academic literature to find out more about what kind of X-Ray tubes we were dealing with, and to try to understand their functioning and to date them. We realised that the tubes represented four stages in the history of the manufacture and design of X-Ray tubes, from  earlier examples to more modern models.

    My tube (above) is an early example of an X-Ray tube known as Jackson Tube or Focus Tube. This particular example was produced by a company based in London, Newton & Co. The presence of the company’s name and address, Fleet Street London, inscribed on the metal plate contained in the tube, led us to think that the tube was made before 1930, when the company moved from Fleet Street to Wigmore Street.
