In his blog no. 387 Jack Windsor Lewis drops the name of former BBC announcer Patricia Hughes, about whom he writes: "[she] was noted for the elegance of her (old-fashioned) speech."
She joined the BBC as a secretary in 1944. In 1946 she became an announcer on the General Overseas Service, later on the Home Service, Light Programme and Third Programme. She left the BBC in 1962 to look after her family, but returned in 1969. She was allocated to the Radio 3 team where she stayed until she retired in 1983.
