Egon Wellesz was an Austrian-born composer and musicologist from Vienna who began his career in the early 20th century, composing operas, orchestral, chamber and choral works while developing a parallel scholarly interest in Byzantine and medieval music. His music blended late-Romantic and early modernist techniques, and after emigrating to Britain in 1938 he continued to compose and to publish research that helped shape twentieth-century scholarship on Byzantine chant and liturgical repertoire.
