	I have a book in my book case at work which describes the history of
waveform measurements, going back to acoustic waveform measurements
using a "sensitive gas flame" and rotating mirror time base.  Can't
remember the exact title, but the author is named Phillips and it is a
British publication.  Things were surprisingly advanced by 1890, but
Braun's work came along a bit later.  There's no way of knowing if Tesla
ever looked at a waveform, but I'd bet he understood them from an
analytical approach.
