Walking toward the Wagner Free Institute of Science near Temple University in Philadelphia in October, I was a little nervous. My friend Hannah and I thought we were going to go back in time and never return.
Why the concern, you ask?
We attended an annual magic lantern slide salon, of course. You can think of magic lanterns as the pre-cursor to slide carousels, projectors, and perhaps even motion pictures. When they first became popular in the eighteenth century, magic lanterns projected their scenes on glass onto walls or other backgrounds using an artificial light source. In the nineteenth century, as the Brooklyn Museum explained, the slides and the machine provided a way for lots of people to learn from the new photographic medium. (Not all slides are of photographs, though.) Modern machines, like the one we saw at the festival, are electrified. The projector we saw holds two glass slides at a time that are swapped out manually. The Wagner was an exciting place to attend such a salon, as the auditorium dates to 1865 and has hosted many a magic lantern presentation.
I learned a lot from this event. Quite frankly, I thought the presentation would be more transformative (see reference to concern about going back in time). But in fact, the visual experience of seeing the slides merely echoed projector or slide carousel presentations. The images did appear more crisp than what contemporary projectors seem to be capable of reproducing. What I found most interesting was the breadth of lantern slide collections in the region and how underutilized they are as archival sources. There may be good reason for this. If you ever handle these slides, you sense immediately how fragile they are. You drop it, it breaks (speaking from experience at an antique mall last year).
But that did not stop these archivists from institutions as varied as the Chemical Heritage Foundation, Penn Museum of Archaeology and Anthropology, and Philadelphia Museum of Art from generously bringing their fragile collections to the Wagner and putting on a show. Some archivists used historic scripts. Others created wholly contemporary interpretations of old slides. Some mixed the two. We learned about how workers at the Stetson hat manufactory, which was based in Philadelphia, made its famous hat. We took a tour through the galleries at the Philadelphia Museum of Art. And we all cooed over a basket of baby lions born at the Philadelphia Zoo.
The festival was part of Archives Month Philly. Looking forward to more fun events next year, even if we do not go back in time or confront magic. This was, after all, held at an Institute of Science.
