In this episode, I chat with Professor Louis Epstein. Professor Epstein is a historical musicologist specializing in early twentieth-century French music, digital mapping, and the science of teaching and learning. His book The Creative Labor of Music Patronage in Interwar France examines collaborations between patrons and composers that shaped French classical music between the world wars. A recipient of fellowships from the Fulbright Program, the Whiting Foundation, and the Mellon Foundation, he has published in journals including Music & Politics, Journal of Musicology, and Journal of Music History Pedagogy. Professor Epstein co-founded Open Access Musicology and leads The Musical Geography Project, an interactive digital mapping initiative that earned him the 2016 American Musicological Society Teaching Award. At St. Olaf College, he previously served as Co-Director of the Center for Innovation in the Liberal Arts.
