  • Magic Lantern Slides and Historypin

    By Nicholas J Booth, on 12 July 2016

    This is a guest post by Bethany Gugliemino, a Museum Studies MA Student carrying out her placement with the UCL Teaching and Research Collections.

    Hello! In my last post, I told you a bit about my work with UCL’s magic lantern slide collection and shared some of my favourite slides. Today, I want to show you where you can see more of this collection and even help us identify some of the more mysterious content.

    As I’ve been cataloguing the slide collection over the last few months, I’ve created a separate list of slides that show an identifiable (or potentially identifiable) location somewhere on earth. This is a shorter list than you might think, since so many of the slides are lecture notes, graphs, and diagrams of scientific equipment. Working with this list, I’ve begun uploading images of these slides to the website Historypin. This site allows users to upload historic images and pin them to a specific location and to create collections and tours of different subjects.

    You can see UCL’s collection of images on Historypin here. Zoom in or out on the map on the left and adjust the date range to filter the slides that appear in the gallery on the right.

    So far, there are images ranging from Alexander Graham Bell’s family home in Canada to officers inspecting a wireless radio installation in St. Petersburg. (more…)

    Some favourite magic lantern slides

    By Nicholas J Booth, on 14 March 2016

    This is a guest blog written by Bethany Gugliemino, a Museum Studies MA Student on a work placement with the UCL Teaching and Research Collections. 

    Hello! My name is Bethany and I’m a museum studies student here at UCL. I’m currently completing my work placement with the UCL Science and Engineering Collections, specifically working on the collection of magic lantern slides held in the Electrical Engineering collection. You may remember reading about these slides before on the blog when a previous intern began cataloguing the collection. Since those posts covered what lantern slides are and how they’re made and an overview of the main contents of the collection, I thought I would give you some examples of my favourite slides I’ve found so far.

    JA Fleming – Discoveries From The Archive.

    By Nicholas J Booth, on 24 July 2015

    This guest blog has been written by Kelsey Svaren, a placement student who has been working with us over the past few months. 

    A few weeks ago I spent some time in UCL Special Collections working my way through the 24 boxes of material that John Ambrose Fleming left to UCL. I was able to look at these boxes in the span of four days, and let me tell you that is not an easy feat! Although I spent more time on certain boxes and documents than others, I feel I got a good overall view of what Fleming wanted UCL to have in its possession and can understand how the University’s history is interwoven with that of Fleming’s. During this time, I have been able to make some generalised conclusions about this man; the one who gave us the technology for so many inventions that people find themselves dependent upon today.

    Finding meaning in the Thermionic valve

    By Nicholas J Booth, on 26 May 2015

    This guest blog has been written by Kelsey Svaren, a placement student who has been working with us over the past few months. 

    Hi, my name is Kelsey and I am current MA Museum Studies student here at UCL. As part of my program, I am required to undergo a placement where I work on a museum related project. I have spent the last month working closely with Nick Booth, curator of the Electrical Engineering Collections at UCL. I have spent this time researching the numerous thermionic valves in the collection.

    Before I started my placement, I had a vague idea of what a thermionic valve is. I knew that it could be used in technologies, such as radios and telephones, to receive and amplify radio signals. Other than that, I was pretty clueless. Since I have started my placement, I have learned more about thermionic valves than I ever thought I would!

    The thermionic valve is especially important to UCL, because it’s inventor, John Ambrose Fleming was a professor at UCL and helped to develop the Electrical Engineering Department that we see today.

    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).

    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.

    Unpacking UCL’s Magic Lantern Slide Collections

    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…)
