This study introduces an example of interdisciplinary course in oral history and theater held at K University. Wol-Wall Festival was run by Lee Hae Kyoung, a professor of theatre from 2009 to 2011 in Bukjeong village in Sungbuk-dong. I also took part in the festival as a historian. In the festival, the residents of Bukjeong village themselves became actors and performed a play representing their own life histories. As a project of saving the Yeomcheon bridge handmade shoes street in 2017, the oral history and the theater were combined together through a resident-participatory interdisciplinary course. In this interdisciplinary class, the life histories of shoemakers in Yeomcheon bridge area were recorded and the historicity of the Yeomcheon bridge area was explored along with the history of handmade shoes. The results of the course were published as a book of oral life history. And some of the shoemakers played the role of themselves in a play representing their own life histories. This interdisciplinary course confirmed the positive effects of combination of oral history and theater. The problem that the interviewee is alienated from his or her oral data could be overcome in this way. If the method of communication in oral history focuses on story rather than letter, the interviewees who have been objects of the researchers could become active subjects who tell their own stories.
