The Jewish Encyclopedia (https://en.wikipedia.org/wiki/Jewish_Encyclopedia) contains a sizeable entry on one 'Adolph Klein', allegedly born on 1829-05-29 in ther German city of Halle (Saale).
Puzzlingly, hardly anything seems to have survived of his writings (or at least: to have found its way to the internet).
For a historical research project, I need to know:
- Are there indications (over and above the few that I'll list below) that this 'Adolph Klein' actually lived? If so, was this 'Adolph Klein' Jewish in any meaningful way?
- Has anything survived of his writings (or of the journals he is said to have edited) and if so, where can those be read? (There seems to be nothing on the internet.)
The above-mentioned encyclopedia-entry lists the following titles of texts Klein allegedly wrote (none of them returned any result in the currently largest internet search engine, except for one hit only: above-mentioned encyclopedia-entry, which is why one may get the idea that this character might be entirely fictional)
i. "Anthropologie und Makrobiotik" (i.e. 'anthropology and macrobiotics')
ii. "Der Chemisch-Mechanische Theil des Menschlichen Organismus und Seine Lebenskraft" (i.e. 'the chemico-mechanical part of the human organism and its vis vitalis')
iii. "Die Geistbewusste Persönlichkeit und Ihre Unvergänglichkeit als Weltprinzip" (i.e. 'the mind-conscious personality and its imperishability as a world-principle')
iv. "Die Magnetischen Funktionen des Eisengehaltes im Blute" (i.e. the magnetic functions of the iron-content in the bloodstream')
v. "Geheimnissvolle Funktionen der Sympathischen Ganglien" (i.e. 'mysterious functions of the sympathetic ganglia'; cf. https://en.wikipedia.org/wiki/Sympathetic_nervous_system)
vi. "Philosophie und Anthropologie" (i.e. 'philosophy and anthropology')
vii. "Religions-Einigung" (i.e. 'unification of religion(s)')
viii. "Sozialpolitische Beiträge zur Judenfrage." (i.e. 'socio-political contributions to the Jewish question')
ix. "Ueberwindung des Wissenschaftlichen Materialismus" (i.e. 'the overcoming of scientific materialism')
x. "Weshalb Theologie, Materialismus und Spiritualismus in Bezug auf das Menschenräthsel zu Falschen Schlüssen Gelangen?" (i.e. 'why theology, materialism and spiritualism arrive at wrong conclusions in regard to the puzzles of humanities')
xi. "Wissenschaftliche Beiträge zum Hypnotismus" (i.e. 'scientific contributions to hypnotism')
It is also said that this Adolph Klein worked as an editor of the following journals:
"Berliner Eisenbahn-Zeitung" (i.e. 'Berlin railroad newspaper)
"Das Rothe Kreuz" (i.e. 'the red cross')
"Deutsche Frauenblätter" (i.e. 'German women letters')
"Gross-Lichterfelder Wegweiser" (i.e. 'guidepost for gross-lichterfeld')
I could not find any scans of these journals (or even of libraries where they might have been preserved).
Adolph Klein is not listed in www.deutsche-biographie.de. (I searched for `Adolf Klein', too, to allow for variant spellings, but---while there are several such entries---none came even close to agreeing with the entry in the Jewish Encyclopedia).
One 'Friedrich Wilhelm Adolph Klein' is mentioned in an enrollment-book of the University of Königsberger ("Akademisches Erinnerungs-Buch für die, welche in den Jahren 1817 bis 1844 die Königsberger Universität bezogen haben"; https://books.google.de/books?id=A8JLAAAAcAAJ&pg=PP5&lpg=PP5&dq=%22Erinnerungsbuch+fur+die+welche+in+den+Jahren+1817+bis+1844+die+Konigsberger&source=bl&ots=8uiawZqQt3&sig=eeawzmw-hVjZdEWhXg62OF2qEoI&hl=en&sa=X&ved=2ahUKEwjZhPGlu7XeAhXBDuwKHUdkDX4Q6AEwC3oECAEQAQ#v=onepage&q=%22Erinnerungsbuch%20fur%20die%20welche%20in%20den%20Jahren%201817%20bis%201844%20die%20Konigsberger&f=false). However, while the location of the university of Königsberger is consistent with the information given in the Jewish Encyclopedia according to which Klein worked as a medical doctor in Königsberger, this 'Friedrich Wilhelm Adolph Klein' cannot be the 'Adolph Klein' I am looking for, for the simple reason that he is said to have been born in 1829 while `Friedrich Wilhelm Adolph Klein' is said to have enrolled at University of Königsberg in 1830; no 1-year old has ever seriously enrolled at a university.
The pseudonym `Nielk Floda', given in the entry in the Jewish Encyclopedia is listed as part of a long list of pseudonyms in 'Meyers Konersationslexikon', and is resolved as 'Dr. Adolf Klein', but nothing more than that is said (also, this information is already in the entry in the Jewish Encyclopedia).
