Paul Hereford Oliver MBE (25 May 1927 – 15 August 2017) was an English architectural historian and writer on the blues and other forms of African-American music. He was equally distinguished in both fields, although it is likely that aficionados of one of his specialties were not aware of his expertise in the other. He wrote some of the first scholarly studies of blues music, and his commentary and research have been influential. Source: Wikipedia (en)
