The visual culture of the sciences has become a focus for increasing attention in recent literature. This is partly a result of the concern with examining the material culture of the sciences that has developed over the last few decades. Increasing attention has also been devoted to understanding science as spectacle and to trying to understand the spaces where scientific performances, variously understood, take place. This essay surveys some aspects of the visual culture of the sciences in the long nineteenth (...) century. I examine the way visual scientific performances---such as magic lantern shows, optical illusions, and public experiments---were put together. I suggest in particular that if we want to understand the ways in which nineteenth‐century sciences appealed to their audiences we need to pay close attention to these kinds of performances, their performers, and the material and social resources that were deployed in their staging.
