Alan Blumlein is a true lost genius, an engineer, who during his brief
life propelled Britain to the vanguard of the modern electronics world.

Working for EMI in the 1930s, he was at the forefront of a revolution,
which gave us recorded sound, television, and radar.

In the field of audio he devised an entire recording system for EMI,
the basis of its fortune for decades.
