Alfred Price
Some 10-15 years ago I used to give talks to local aviation societies and IEE branches on Radar and/or EW.
I turned up to give my EW one to the Uppingham District Aviation Society only to find Alfred Price on the front row.
Since a reasonable amount of my EW talk used information (and diagrams) from his books I was a bit twitchy - but afterwards he complimented me. Phew!
A gentleman. RIP
