Zionist publicist; studied in Berlin and Leipzig; 1919 Editor for the "Jüdisch Jugendblätter" Editor for the "Wiener Morgenzeitung" since 1919; Factory director in Berlin and Bank Director; 1925 emigration to Palestine; Change of name to MARGALIT; Director of the Bank Leumi Lejisrael [Anglo-Palestine Bank]; moved to Kiriat Tivon; Since 1956 scientific works, including studies of the old-semitic [altsemitisch] and sumeric cultures; Publications [see below] [8, Footnote 175].I'm not sure about these references to the Wiener Morgenzeitung: most sources (i.e. those I've seen so far) only mention his brother Isidor. But the reference to the "Jüdisch Jugendblätter" is also repeated here[8, Footnote 153].
Other warmongering german Zionists like Heinrich Margulies published articles in Jüdischen Rundschau published articles with inflammatory titles like "Der Krieg und die Zurückgebliebenen" oder "Wir und der Krieg". [...] Gershom Scholem and 15 members of the wrote an angry letter to the editors objecting to the war. The letter was also signed by 15 members of the "Jung-Juda" associated, but it wasn't published, and the president of the Zionistischen Vereinigung Deutschlands, Arthur Hantke, reprimanded Scholem and two others as he feared that if the letter were to be published, then the Vereinigung could be banned for unpatriotic behaviour.
Although I didn't find his speech - or indeed the figure of this Heinrich Margulies - particulary sympathetic, in my opinion his objection does have some merit.
The second general speaker, Mr. Heinz [!] Margulies, tried to counter Dr. [Robert] Weltsch's remarks and made polemic comments about Buber's influence in the jewish Youth Movement, as his misunderstood ideas could lead to a really bad outcome. [6, Footnote 175]
... Heinrich Margulies, whose article caused Scholem's first anti-war activity, turned against his mentor at a youth conference after the war. Margulies accused Buber of "spiritualizing" Zionism (Vergeistung des Zionismus), presumably by ignoring the need for a concrete program of emigration to Palestine.
Memo to self: Expand the controversies.
"Es gibt kein Himmelreich auf Erden", Heinrich Margulies - ein sekulär Zionist Vera has provided me (in e-mails and through her book) more details of Heinrich's life, which now appear here on the website. If you can read german, then I can recommend that you read this book for a very detailed account of the above mentioned controversies.
In 1913 he then moved to Berlin.
Damals war Margulies Vorstandsmitglied und stellvertretender General Direktor der Engelhard-Brauerei in Berlin gewesen und wurde im Laufe des Jahres 1923 von seinem Arbeitgeber nach Mailand geschickt, [...] 1923. [9, s.273]
At that time Margulies was a board member and assistent general manager of the Engelhard Brewery in Berlin and in 1923 he was sent by his employers to Milan [...].

In 1923 he was appointed managing director ("Consiegliere Delegato") of the "Societa per l'Indistria Birraria", a Berlin-Vienna subsidiary of the Engelhardt-Brauerei. In 1925 he was already planning to emigrate to Israel, hoping to work for the Anglo-Palestine-Company, later Anglo-Palestine Bank (A.P.B. In 1948 this became the Israel National Bank, the Bank Leumi leIsrael). He finally managed to get a visa in September 1925, with Nanni and his three children following him in December 1925. [9, s.273f]
After the war he was sent on research trip to the USA. Here he spent several months studying methods for financing small and medium sized industrial firms and operations.
The youngest brother, Heinrich, was already influenced by his two older brothers in the zionist Youth Movement, where he excelled. As a young man he published a two-volume "Critique of Zionism" and emmigrated soon after World War I to Erez Israel, where he has become a leading economist. Although he has attained an important position in his contry's financial economy -- he is one of the directors of the Anglo-Palestine Bank Ltd. -- he is often enticed back to his literature and architectural studies. He recently published with "Dwir", Tel Aviv, an interesting piece of archeological research "Paroh schebijmej Josef" (Joseph's Pharoah), under the pseudonym of H. Owadjy.
