Is there any way of finding any details on Mr Epstein - the inventor of the Epstein frame (Epstein square)? I searched in the deepest places in Google and the most I could find it is that probably his first name started with "I" or "J", but that is all.
Any papers published by him?
Where did he worked? There must be some university records somewhere?
It is a bit embarrassing to the scientific community I think that the Epstein frame is so widely known, but there is not even a snippet of information on the inventor himself.
Dear Stan,
I've just managed to find a reference to Epstein's (first?) publication. Here it is.
Epstein, J., Magnetic Testing of Sheet Steel, Elektrotechnische Zeitschrift, 1900, vol. 21, pp. 303-307.
If you can get an access to this journal, perhaps we can learn where from his paper was submitted. At least we know that his first name starts with J (Josef?).
Best, Sergei
Dear Stan, here is another bit of information about Joseph Epstein (yes, his first name is definitely Joseph). See the atached link (sorry, it's in German!). If I understood it correctly, Prof. Dr. Joseph Epstein is from Leipzig but he spent some time in the very famous place---Physikalischer Verein (Frankfurt am Main, Germany). Here is an extract from their site on the history of this Institute: "Der Physikalische Verein hat 1889 seine Elektrotechnische Lehranstalt gegründet und damit die erste Elektrotechnikerschule in Deutschland, wenn nicht der Welt, geschaffen. Der erste Leiter wurde Prof. Dr. Joseph Epstein (18 -1930) aus Leipzig; nicht nur die Lehranstalt und der Physikalische Verein sondern das technische Ausbildungswesen in Deutschland verdanken ihm sehr viel."
Best, Sergei

Joseph Epstein got his PhD degree from the University of Leipzig in 1887. The subject of his PhD thesis was about chronometry (Die logischen Prinzipien der Zeitmessung).

Dear Sergei Sir,
Thank you so much for working so hard to provide such inaccessible information to us. You are really doing a good job on this scientific platform. Please keep it up. We need some true and sincere spirits as you. Keep rocking in the same way !!!!!!!
Sergei: I did find the information about the published paper you mentioned, but it was difficult to follow it any further, especially that I don't speak German.
Also, I am trying to think how could we get access to this journal.
Regards
Stan
Hi, interesting discussion. I can help with German and in Linz we are working on similar topics. Regards, Gerd
Gerd,
Thank you for joining in. Would you be able to look up some German encyclopedia or some other source? There is very little information about the man?
Regards
Stan
Hi,
I have already asked our university's library for the article. I will keep you posted about any news. With a quick search I was not able to find a biography in German.
Regards, Gerd
Gerd,
Fantastic news! I am hesitating to ask but if it is not too long could you possibly translate it into English? Or just send me the original?
Regards, Stan
I did not get it so far. If there is a possibility to get it, we can discuss the other options ;-) But I will do my best.
Thank you for posting the link to it. Just need to learn German now to translate it! :)
Thank you, too. I downloaded it and gave it to a colleague. Hope he will have time soon to translate it.
Branko Koprivica thank you for sharing the link. i will share it to colleagues
