Stereo superhero

I WAS delighted to learn of a Grammy f or Alan Blumlein, inventor of stereo (Mail).

I worked for EMI for 17 years in the Fifties, Sixties and Seventies, including the time of the launch of stereo LPs in the UK.

He was referred to, almost to the point of reverence. And he was always r eferred t o as A. D. Blumlein, never as Alan.
