Is any more known about John White?
John H. White is an important figure in the talking machine history. I cite Raymond R. Wile (Etching the Human Voice: The Berliner Invention of the Gramophone):
On November 18, 1887, Berliner suffered another blow. He had applied for an additional patent on November 7, 1887, [on "Gramophone"] and he was now informed that his application was being placed in interference with one by John H. White who in his specifications showed a laterally undulating record cut into wax.
White's application comprised a system with a combination of a diaphragm, a pivoted stylus and a laterally undulating sound record cut into wax. In Berliner's testimony the cutting into wax also was emphasized.
It is possible that Berliner’s later reluctance to cut directly into wax stemmed from his experience in this interference. [My emphasis]
[White’s application was abandoned on March 31, 1888 and is now lost to history.]
