Music professor Eileen McCall Washington (1907-1994) taught vocal art of Renaissance music at San Francisco. She organized the Madrigal Singers, the first group on the West Coast devoted to studying the English madrigal, contrapuntal folk songs written for mixed voices and performed a capella, in Spring 1931. They were so widely acclaimed that they performed bi-weekly concerts broadcast over the western NBC radio network heard locally on radio stations KPO and KYA, and they traveled to Stanford University to perform and teach Stanford students about early music.
