This project proposes a two-week NEH summer seminar, aimed at higher education faculty members, including graduate students and contract or contingent faculty. To be hosted at the University of Denver in Summer 2021, this seminar brings together three trained historians whose work focuses on sound and radio broadcasting, and who have professional homes in three different disciplines (area studies, history, and religious studies). It aims to support participants in studying the roles of sound in 20th century history, using radio broadcasting as a key case study, and in developing initiatives for incorporating sound and material evidence of sound into their pedagogy.
