This article introduces the exhibit called "Out from Under: Disability, History and Things to Remember" and positions it as a focal point for exploring questions of disability, museum exhibition and adult education. Created by the School of Disability Studies at Ryerson University in Toronto, "Out from Under" was the first public exhibit of disability history in Canada (2007-2014) and the first to be displayed at the prestigious Royal Ontario Museum. With adult education in mind, we unravel some of the strands of teaching and learning woven through this lengthy, creative project. Highlighting a complex blend of actors and forms of knowing, we consider the knowledge activated through exhibit creation as well as a subsequent formal study of visitor responses. We situate the whole project as a robust and rare example of social movement learning through practices that crossed the borders between disability/mad rights movements, an undergraduate programme of Disability Studies and a major Canadian museum.
