Mr. Edison, the inventor of the famous lamp-black button transmitter, which he christened later as “The Carbon Telephone,” has himself stated in his account of his inventions,[7] that he was started upon this line of investigation by having put into his hand, by the late Hon. Mr. W. Orton, a manuscript translation of Legat’s Report on Reis’s Telephone, given in the Journal of the Austro-German Telegraph Union (see Translation, p. 70). So that he was, therefore, aware at least of this: that in Reis’s instruments “single words uttered, as in reading, speaking, and the like, were perceptible indistinctly, nevertheless, here also the inflexions of the voice, the modulations of interrogation, exclamation, wonder, command, etc., attained distinct expression.” So far as Mr. Edison is concerned, therefore, Reis is his starting-point by his own direct avowal. Professor Graham Bell has not failed to acknowledge his indebtedness to Reis, whose entry “into the field of telephonic research” he explicitly draws attention to by name, in his “Researches in Electric Telephony,” read before the American Academy of Sciences and Arts, in May 1876, and repeated almost verbatim before the Society of Telegraph Engineers, in November 1877. In the latter, as printed at the time, Professor Bell gave references to the researches of Reis, to the original paper in Dingler’s ‘Polytechnic Journal’ (see Translation, p. 61); to the particular pages of Kuhn’s volume in Karsten’s ‘Encyclopædia’ (see p. 106), in which diagrams and descriptions of two forms of Reis’s Telephone are given; and where mention is also made of the success with which exclamatory and other articulate intonations of the voice were transmitted by one of these instruments; and to Legat’s Report, mentioned above (and given in full on p. 70). Professor Bell has, moreover, in judicial examination before one of the United States Courts expressly and candidly stated,[8] that whilst the receivers of his own early tone-telephones were constructed so as to respond to one musical note only, the receiver of Reis’s instrument, shown in Legat’s Report (as copied in Prescott’s ‘Speaking Telephone,’ p. 10), and given on p. 109 of this work, was adapted to receive tones of any pitch, and not of one tone only. It is further important to note that in Professor Bell’s British Patent he does not lay claim to be the inventor, but only the improver of an invention: the exact title of his patent is, “_Improvements_ in Electric Telephony (Transmitting or causing sounds for Telegraphing Messages) and Telephonic Apparatus.” So far as Professor Bell is concerned, therefore, he is guiltless of stigmatising the Reis instrument as a mere “tone-telephone.”
