The electromagnet ... will be demagnetised and magnetised correspondingly with the condensations and rarefactions of the mass of air, ... and the armature ... will be set into vibrations similar to those of the membrane in the transmitting apparatus.—(Legat’s Report, Zeitschrift, p. 128, 1862.) [p. 77.] The current traversing the coils of the electromagnet E, occasions an increase and diminution in its intensity, and the armature A1 is thrown into vibrations ... and thus imparts to the air at n1 a facsimile copy of the motion of the air that acted upon the membrane n.—(Specification of British Patent, No. 4765, Dec. 9th, 1876, p. 17.)
The transmitter, Fig. A, consists of a conical tube ... closed by a membrane ... by speaking ... into the tube ... there will be evoked a motion of the membrane ... (op. cit.) A cone A is used to converge sound vibrations upon the membrane.
When a sound is uttered in the cone the membrane a is set in vibration....
The apparatus ... offers the possibility of creating these vibrations in every fashion that may be desired, and the employment of electro-galvanism gives us the possibility of calling into life, at any given distance, vibrations similar to the vibrations that have been produced, and in this way to reproduce at any place the tones that have been originated at another place.—(Legat’s Report, op. cit.) ... and thus electrical undulations are created upon the circuit E b e f g.... The undulatory current passing through the electromagnet f influences its armature h to copy the motion of the armature c.... These undulations are similar in form to the air undulations caused by the sound.
>As soon therefore as it shall be possible ... to set up vibrations whose curves are like those of any given tone or combination of tones, we shall receive the same impression as that tone or combination of tones would have produced upon us.—(Memoir ‘On Telephony,’ p. 60.) [p. 55.] —that is, they are represented graphically by similar curves....
A similar sound to that uttered into A is then heard to proceed from I.—(Specification of U. S. Patent, No. 174,465.)
Any sound will be reproduced, if strong enough to set the membrane in motion.—(Letter to Mr. Ladd, 1863.) [p. 84.] There are many other uses to which these instruments may be put, such as ... the telegraphic transmission of noises or sounds of any kind.—(Ib.)
the armature belonging to the magnet will be set into vibrations similar to those of the membrane in the transmitting apparatus.—(Legat’s Report, 1862.) [p. 77.] I would have it understood that what I claim is:—... Tenth. In a system of electric telegraph or telephony consisting of transmitting and receiving instruments united upon an electric circuit, I claim the production in the armature of each receiving instrument of any given motion by subjecting said armature to an attraction varying in intensity, however such variation may be produced in the magnet, and hence I claim the production of any given sound or sounds from the armature of the receiving instrument by subjecting said armature to an attraction varying in intensity in such manner as to throw the armature into that form of vibration that characterizes the given sound or sounds.—(Specification of British Patent, No. 4765, Dec. 9, 1876.)

One cannot help thinking that some claims to great inventions are just a little “too previous.”

If it should still be said that Reis’s method of transmitting speech, whether it did its work by undulatory currents or no, was avowedly imperfect, and that therefore such a claim as that quoted above is justified by the subsequent invention of an instrument the articulation of which was more reliable, let us compare what each inventor has said about the imperfections[54] of his own instrument.

Reis.Bell.
That which has here been spoken of will still require considerable improvement, and in particular mechanical science must complete the apparatus to be used.—(Legat’s Report, 1862.) [p. 78.] It is a mistake, however, to suppose that the articulation was by any means perfect.... Still the articulation was there, and I recognized the fact that the indistinctness was entirely due to the imperfection of the instrument.—(‘Researches in Telephony,’ Journal of Soc. of Telegr. Engineers, Dec. 1877.)

If it should be said that Bell is here speaking only of an early and experimental form, and not of his real invention, it should be remembered that Bell here refers to the apparatus with cone and membrane, identical with that exhibited at Glasgow in September, 1876, by Sir William Thomson (who had received it from Bell) and by him described as the very “hardihood of invention,” and “by far the greatest of all the marvels of the electric telegraph.” It certainly worked upon the principle of undulatory currents,[55] whether it articulated or not. Bell had himself, speaking in May 1876, before the American Academy of Arts and Sciences upon his researches, even more explicitly admitted the imperfections of his own instrument.

The effects were not sufficiently distinct to admit of sustain ed conversation through the wire. Indeed, as a general rule, the articulation was unintelligible, excepting when familiar sentences were employed.—(Proceedings of American Academy of Arts and Sciences, vol. xii. p. 7.)

Yet this most imperfect machine, of which the articulation was, as a general rule, unintelligible, had, two months previously, had a patent granted to it as a new invention, the claim being for “the method of, and apparatus for, transmitting vocal or other sounds telegraphically, as herein described, by causing electrical undulations similar in form to the vibrations of the air accompanying the said vocal or other sounds, substantially as set forth.”

If then mere mechanical imperfections do not make an invention any the less a true invention capable of legal recognition, it would be dishonest to the last degree to deny to Philipp Reis the honour of his invention, of which he honestly and openly stated both the successes and the imperfections. He told the world what he aimed at, and in what measure success had crowned his aims. His claim to be the inventor of the Telephone he considered to be justified by that measure of success. If he was so far in advance of his time that the world was unprepared to receive or use the splendid discovery which he gave freely to it, that was not his fault; nor does neglect or apathy make him in one single degree the less entitled to the credit of his inventions. Tulit alter honores has not unfrequently been truly said concerning the men of genius who have had the misfortune to live in advance of the age.

But posterity does not let the names of such truly great ones perish in the dust. The inventor of the Telephone will be remembered and honoured in the coming if not in the present age.
