This dissertation explores the figure of the mad scientist in Victorian literature through some of the most enduring literary examples, viewing these works not as anti-science cautionary tales but rather thought experiments for dealing with hazardous scientists and hazardous science. It makes a claim for a spectrum of hazardous scientists from the beneficial to the truly mad and argues that the primary difference between them is a matter of socialization. It argues that these novels advocate for the scientist and society to negotiate and co-construct a mutually beneficial symbiotic relationship.
