Paul Anderson is no relation to Andy, whose real name wasn't Anderson anyway. He's also a very bright guy - I had the pleasure of visiting him at his home a couple of months ago.
The RADIO NORD antenna was not developed by one, but by John. Mullaney, a radio engineer in the US military in the 40s I think, who set up his own stations and engineering consultancy in the 50s, which is how he came into the Radio Nord fold. His son (also John) took over the business in the 80s and he too retired just before the pandemic. Mullaney Engineering is still a revered name in broadcast circles and is now run by Tim Sawyer.
I have the full spec' and operating instructions on the NORD antenna - in the 60s it was protected by all kinds of US military restrictions, but this are now lifted. Contact me direct if you want more details.
