VHF tropo (non ducting) history

Whilst trying to locate an up-to-date list of VHF 2m beacons I am likely to be able to copy here on a halo, I chanced upon a site with a history of non-ducting tropo (NDT) going back to the work by Marconi in the 1920s and 1930s. See http://www.quercus.demon.co.uk/thistory.html. Interesting reading.
