Willi Apel (1893-1988)

A German-American musicologist, made a substantial contribution to the understanding of early music through his many publications.  Among these are "The Notation of Polyphonic Music, 900-1600" and "Gregorian Chant" (1958).  Many generations of American music students have relied on "The Harvard Dictionary of Music" and the two-volume "Historical Anthology of Music".  This latter publication was a collaboration with Archibald T. Davison.
