  • 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.

    Re-packing UCL´s Magic Lantern Slides

    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).

    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…)
