Tony Davis has made a good point about adding some English references to the list of references for this proposal. Aside from that, I feel the proposal is well-written and covers all the pertinent material. It makes a strong case for this milestone, and I support it fully. We usually dont like to focus on one individual in establishing a milestone, but, in this case, this is necessary.- Heinrich Hertz is universally acknowledged to have been the first one to experimentally verify Maxwell's equations, demonstrating the equivalence of radio and light waves, and showing radio waves did travel at the speed of light.
Thank youn for your support. We agree with the recommendation by Tony Davies to add the English translation of the Hertz collection to the list of references.
A very good proposal and a very worthy milestone. I think it is especially meaningful that the plaque will be located in the very building where Hertz conducted his experiments. I am a bit troubled by the last phrase in the citation. Would it be better to say that he "demonstrated the fundamentals"?
We agree that Hertz demonstrated the fundamentals of high-frequency technology. But he did not only demonstrate what others accomplished prior to him. To our best knowledge Hertz himself was the first to build high-frequency transmitters and receivers, to achieve 450 MHz and to successfully work in this high-frequency area. Dieter Mlynski
Under the assumption that the suggestions already made will be addressed, I would add my endorsement of this IEEE Milestone proposal.
The plaque wording is logical and easy to read. I fully support this milestone.
I support the milestone and its wording and I vote to approve it subject to the following. I am surprised there is no mention of Oliver Lodge in the supporting materials since he is usually credited with bringing Hertz into popular recognition. I would add some references as appropriate.
The following is a clip from an exhibit about Lodge that was at the Antique Wireless Association Museum in 2010. The exhibit had signed copies of books, documents, etc. This clip includes the key points and relevant publication titles pertaining to Hertz and Lodge---
"On June 1, 1894, Sir Oliver Lodge delivered his historic memorial lecture “On the Work Of Hertz” at the Royal Institution in London. This landmark lecture ignited the study of wireless telegraphy and the search for a practical commercial means of radio communication. Lodge’s lecture was reprinted in 1894, and then published in 1896 as “Signalling Across Space Without Wires: Being a Description of the Work of Hertz And His Successors”. The Fourth Edition was published in 1909 by The Electrician Printing and Publishing Company, Ltd. in London and was presented by Lodge to the Author’s Club in London, a premier gathering place of well known authors founded in 1891. It includes Lodge’s later remarks concerning the development of wireless telegraphy.
Lodge’s 1894 lecture was the first time Hertzian waves had been publicly demonstrated. He used Lord Kelvin’s mirror galvanometer to forcefully show that his research confirmed Hertz’s independent findings validating Maxwell’s theories. Lodge demonstrated the refraction, reflection and polarization of electric waves, and their passage through stone walls from room to room. These experiments, with some variations, were repeated on August 1, 1894 at meetings of the British Association in Oxford at which Morse code signals were sent by radio for the very first time. Although the intended purpose of the lectures was to expound on the theory of electric waves, they created a sensation by showing the capabilities of wireless telegraphy. The lectures are credited with focusing the interests of many notable engineers and scientists on wireless telegraphy including: Dr. A. Muirhead and Captain Henry B. Jackson (R.N.) in Great Britian, Professor A.S. Popoff in Russia, Nikola Tesla in the U.S., and Augusto Righi (Guillermo Marconi’s mentor) in Bologna, Italy. Yet, Lodge did not pursue his discoveries, and the commercial development of wireless telegraphy ultimately occurred only after Marconi and others found ways to make it feasible. Even so, it was through his now famous lecture that Sir Oliver Lodge is credited with initiating the age of wireless telegraphy and the birth of radio." --Dave Bart
It might be helpful to English speaking readers to add to the list of references the English translation of the collected Memoirs, Letters and Diaries of Heinrich Hertz by Joanna Hertz, to include the later English Translation published in USA in 1977 (translation by L. Brinner, M. Hertz and C. Susskind) ISBN 0-911302-35-2
This book has the German text and the English translation printed side-by-side, allowing a direct comparison of the original and the translation, which seems to me useful for readers with a limited knowledge of German, not sufficient to read the German version unaided.

Thank you for your improving suggestion. We fully agree with it. Could you kindly give us the English title of this trnslation from 1977. We could not find it fromn the ISBN.
Dieter, the title is:
Heinrich Hertz: Memoirs, Letters Diaries / Heinrich Hertz: Erinnerungen, Briefe, Tagebücher (English and German Edition)
If you click on the ISBN link, it will allow you to click on various book vendors (I used amazon.com) and will take you to the book page on those sites, for example http://www.amazon.com/exec/obidos/ISBN=0911302352
