Emile Berliner, the first to record on a disc also called the father of the gramophone; and this is a Grammy Special Merit Award “recognising contributions of significance to the recording field” named after him.
This particular one was awarded to Garrard Eng Ltd in 1971 ‘For the development of a Zero Tracking Error tone arm for disc record reproduction”
The tonearm used on the famous Garrard Zero series of which I’m displaying the examples in my collection on this site.
As far as I’m aware 6 of these plaques were made and this one was for some time on the toolbox of one of the engineers that received the plaque. He sold it to me a few years ago.
