Social Democrat, Cooperative Member, and Jew. Joseph Berkowitz Kohn’s Activism in Late 19th Century Hamburg

Sebastian Voigt

Source Description

Joseph Berkowitz Kohn’s “memoirs” give an account of the eventful life of a Jew born in the Polish town of Leczyca in 1841 who participated in various struggles for emancipation in his homeland. In 1863 Berkowitz Kohn was forced to flee Poland and went to Hamburg, where he set up his own business as a merchant. Beginning in the mid-1870s, he became active in the Social Democratic Party and especially in cooperatives. He became a well-respected personality within Hamburg’s labor movement. Joseph Berkowitz Kohn died in Hamburg in 1905. This short excerpt from the text, which is about 100 pages long, is based on the diary he kept during the last three decades of his life for his ten children and their descendants. Originally not intended for publication, his notes were copied on a type writer by his daughter Sophie. This typescript was given to the Museum der Arbeit in Hamburg, presumably by Inge Henker, a distant relative of Berkowitz Kohn. In 2006 Ulrich Bauche and Gertrud Pickhahn published an annotated edition of his memoirs based on this version. Gertrud Pickhan / Ulrich Bauche (eds.), Joseph Berkowitz Kohn, Erinnerungen.

Caught between Judaism and the Polish fight for independence


Berkowitz Kohn be­gins his au­to­bi­o­graph­i­cal text with a de­tailed de­scrip­tion of his birth place, the Pol­ish town of Leczyca, in which Jews rep­re­sented slightly more than half of the pop­u­la­tion in the mid-19th cen­tury. He stemmed from a fam­ily of mer­chants. The eth­nic di­ver­sity of his home town in­formed his in­tel­lec­tual and po­lit­i­cal in­ter­ests, which were to re­volve around poli­cies to­ward mi­nori­ties, so­cial sol­i­dar­ity, and na­tional eman­ci­pa­tion. In ad­di­tion, the im­por­tance of ed­u­ca­tion in Berkowitz Kohn’s fam­ily en­vi­ron­ment strongly in­flu­enced his fur­ther path in life. For ex­am­ple, he re­counts re­ceiv­ing an atlas of the world as a Bar Mitz­vah gift and there­upon be­came de­ter­mined to see the world for him­self.

In ad­di­tion to his na­tive Yid­dish, he learned He­brew as well as the lan­guage(s) of his en­vi­ron­ment and the major Eu­ro­pean na­tions. Ac­cord­ing to his own ac­count, he first wrote his jour­nal in He­brew be­fore writ­ing pas­sages in French, Pol­ish, and fi­nally in Ger­man. As a young adult, he ex­ten­sively stud­ied the three par­ti­tions of Poland since the end of the 18th cen­tury, which had led to the com­plete dis­ap­pear­ance of any sov­er­eign Pol­ish na­tional state. Dur­ing meet­ings of se­cret pa­tri­otic as­so­ci­a­tions, he passed on his knowl­edge as a basis for Pol­ish na­tional pa­tri­o­tism. He also took part in the next armed re­volt against Tsarist Rus­sia in 1863/64. Fre­quent scenes of frat­er­niza­tion be­tween Poles and Jews could not hide the wide-​spread, Catholic-​inspired An­ti­semitism Berkowitz Kohn had been con­fronted with since his child­hood. After the re­volt was bru­tally put down by Russ­ian troops, Berkowitz Kohn de­cided to flee. He first trav­eled to By­d­goszcz Bromberg via Gdansk Danzig and Toruń Thorn. An ac­quain­tance of his fa­ther’s ad­vised him to go to Ham­burg, not least be­cause one of Berkowitz Kohn’s cousins lived there. He even­tu­ally ar­rived in Ham­burg on April 20, 1864.

Escape to Hamburg. Life as a merchant


At the time of his ar­rival, Ham­burg ex­pe­ri­enced an eco­nomic boom. The pop­u­la­tion had in­creased to more than 250,000 in­hab­i­tants, roughly four per­cent among them of Jew­ish ori­gin. The Jew­ish con­gre­ga­tion num­bered about 12,500 mem­bers and had the au­thor­ity to in­de­pen­dently de­cide on res­i­dence per­mits for (mostly east­ern Eu­ro­pean) mi­grants. Two of its mem­bers, whom he does not men­tion by name, vouched for Berkowitz Kohn. Find­ing em­ploy­ment proved dif­fi­cult for him, how­ever. For a time, he had to make a liv­ing sell­ing lot­tery tick­ets, like his cousin. It was his cousin, too, who showed Berkowitz Kohn Ham­burg’s var­i­ous facets and neigh­bor­hoods when he first came to the city. He was si­mul­ta­ne­ously fas­ci­nated by its vi­brant life and dis­gusted by the vices pre­vi­ously un­known to him, such as pros­ti­tu­tion. He wit­nessed great poverty in the work­ing class neigh­bor­hoods his work often took him to, which awak­ened his in­ter­est in so­cial is­sues. Sell­ing lot­tery tick­ets was gen­er­ally te­dious and did not pay well, so that Berkowitz Kohn soon gave it up and in­stead de­cided to learn a skilled trade. He began train­ing as an um­brella maker.

He even­tu­ally gave up his plan to em­i­grate to the United States of Amer­ica. He did change pro­fes­sions and found em­ploy­ment in his land­lord’s dry goods store. A short time later he started his own leather goods store, which pros­pered yet also meant hard work from early morn­ing until late at night. As an in­de­pen­dent mer­chant, he did re­ceive both a Ham­burg trade li­cense and the sta­tus of cit­i­zen, how­ever. This is how he com­mented on it: “Me, a Ham­burg cit­i­zen!? Oh, for­give me, my dear home­land, my friv­o­lous be­hav­ior, ex­cuse the hounded wan­derer who yearns for peace and seems to get by with­out that most sa­cred sense of duty of the re­cent past, ex­cuse your or­phaned son if he wants to rest in a for­eign fold and wants to pick flow­ers on for­eign mead­ows in order to make wreaths to com­mem­o­rate you.” (p. 98)

Feeling torn between Poland and Hamburg


This quote com­bines many as­pects of Berkowitz Kohn’s dif­fi­cult and event­ful life. Torn be­tween dif­fer­ent coun­tries, forced to flee, and con­stantly re­minded of his ori­gin, he even­tu­ally chose Ham­burg as his adopted home. He later found his po­lit­i­cal home in So­cial Democ­racy, whose so­cial­ist uni­ver­sal­ism pro­vided him, the “haunted wan­derer,” with a solid and si­mul­ta­ne­ously cos­mopoli­tan an­chor. Ini­tially, he was plagued by a bad con­science to­wards Poland, his “dear home­land,” which he left due to his yearn­ing “for peace”. To make up for this re­nun­ci­a­tion and in order to up­hold the mem­ory of his place of birth, he be­came ac­tive in Pol­ish exile as­so­ci­a­tions.

A short time later, Berkowitz Kohn mar­ried Au­guste Gabrielsen, who came from an or­tho­dox fam­ily. Hav­ing tem­porar­ily been es­tranged from Ham­burg’s Jew­ish con­gre­ga­tion, he was now brought into closer con­tact with the com­mu­nity by his wife. In­stead of in­te­grat­ing him­self, how­ever, he at­tempted to re­form it by writ­ing trea­tises on Jew­ish his­tory and giv­ing lec­tures. In the 1870s, when An­ti­semitism di­rected against east­ern Eu­ro­pean Jews in­creased in Ham­burg as in other places, un­like many of his fel­low Jews, he did not re­treat from pub­lic life in order to keep a low pro­file. In­stead he founded a Pol­ish as­so­ci­a­tion, in which Chris­t­ian and Jew­ish em­i­grants con­versed in their na­tive lan­guage and dis­cussed the sit­u­a­tion in their for­mer home­land. Berkowitz Kohn served as head of the as­so­ci­a­tion for many years.

Activism in the Social Democratic movement


More­over, he con­cerned him­self with the in­creas­ingly press­ing mat­ters of the “So­cial Ques­tion.” He wit­nessed the con­se­quences of ac­cel­er­ated in­dus­tri­al­iza­tion in the liv­ing con­di­tions of Ham­burg’s pro­le­tariat, yet he also felt them him­self. The in­ven­tion of new ma­chines meant fi­nan­cial ruin for many shoe­mak­ers, and in the early 1880, it tem­porar­ily bank­rupted his leather goods store just after his tenth child had been born. His sym­pa­thies for so­cial­ist ideas and So­cial Democ­racy grew stronger. Gen­er­ally speak­ing, Jews were ac­tive in the So­cial De­mo­c­ra­tic Party in dis­pro­por­tion­ately high num­bers. Their per­cent­age among So­cial De­mo­c­ra­tic mem­bers of par­lia­ment was much higher than their per­cent­age among the over­all pop­u­la­tion. And not even this: Also many of the party’s lead­ing thinkers were Jews. At the time, Ham­burg be­came the strong­hold of the Ger­man labor move­ment. Its local SPD chap­ter counted 4000 mem­bers in the mid-1870s, which was al­most a fifth of the party’s coun­try­wide mem­ber­ship. Ham­burg was also the lo­ca­tion of sev­eral labor union ex­ec­u­tive boards as well as the cen­ter of the co­op­er­a­tive move­ment.


In this en­vi­ron­ment, Berkowitz Kohn in­creas­ingly be­came ac­tive in the “so­cial move­ments,” as the ex­cerpt from the source states. Wide­spread poverty and poor liv­ing con­di­tions among the pro­le­tariat had made him aware of the ne­ces­sity for a fun­da­men­tal change in so­cial con­di­tions. He con­sid­ered po­lit­i­cal ed­u­ca­tion a key fac­tor in this ef­fort. He was ac­tive in sev­eral Work­ers’ Ed­u­ca­tional As­so­ci­a­tions Ar­beit­er­bil­dungsvere­ine and in var­i­ous co­op­er­a­tives. Using his com­mer­cial knowl­edge, he ex­plained larger eco­nomic con­texts to the work­ers: “Upon closer in­spec­tion of the new so­cial laws, one soon found in the union meet­ings and in the form­ing of co­op­er­a­tives, a large field for sow­ing the seed of eco­nomic ed­u­ca­tion for the work­ing class. In Ham­burg’s Old Town and in Barm­bek, I taught his­tory, ac­count­ing, and basic po­lit­i­cal econ­omy at the School for Work­ers’ Ed­u­ca­tion Arbeiter-​Fortbildungsverein. I later joined the board of the Ed­u­ca­tion As­so­ci­a­tion in Eimsbüttel, and I was able to re­cruit good teach­ers of Ger­man, Cal­cu­lus, Writ­ing, Draw­ing, Stenog­ra­phy, etc.” (pp.111)


As chair­man of a pro­le­tar­ian ed­u­ca­tional as­so­ci­a­tion, he at­tracted the at­ten­tion of the po­lice, who, act­ing on the Anti-​Socialist Law The “Law against the Pub­licly Dan­ger­ous En­deav­ors of So­cial Democ­racy,” [Sozial­is­tenge­setz] passed on Oc­to­ber 19, 1878. of 1878, sus­pected the as­so­ci­a­tion of being a So­cial De­mo­c­ra­tic front. How­ever, state re­pres­sion was un­able to pre­vent the rise of So­cial Democ­racy in Ham­burg or in any other Ger­man city. In fact, the So­cial De­moc­rats gained a sig­nif­i­cant num­ber of votes in the course of the 1880s. Party-​affiliated news­pa­pers were es­tab­lished and var­i­ous work­ers’ as­so­ci­a­tions were founded while Ham­burg’s labor union move­ment grew as well.

After the Anti-​Socialist Law was re­pealed in 1890, Ham­burg was rep­re­sented in par­lia­ment by Au­gust Bebel, one of the lead­ing and most in­flu­en­tial Ger­man So­cial De­moc­rats, and Jo­hann Hein­rich Wil­helm Dietz, founder of the J.H.W.-​Dietz pub­lish­ing house, among oth­ers.

Berkowitz Kohn’s political legacy


The co­op­er­a­tive move­ment also saw a fur­ther boost dur­ing this time. In 1899, Berkowitz Kohn took on a lead­ing role in the found­ing of “Pro­duk­tion,” a con­sumer co­op­er­a­tive and build­ing and sav­ings so­ci­ety, which was to be­come one of the most im­por­tant so­cial­ist con­sumer co­op­er­a­tives. He re­mained ac­tive in Ham­burg’s labor move­ment until his death on April 3, 1905. His im­por­tance for Ham­burg’s So­cial De­mo­c­ra­tic Party be­comes ev­i­dent in the nu­mer­ous obit­u­ar­ies hon­or­ing the decades of ser­vice this Jew­ish com­rade de­voted to it. “Vorwärts,” the party’s cen­tral organ, was among the pa­pers re­port­ing his death, and sev­eral co­op­er­a­tives placed death no­tices in Ham­burg’s work­ers’ news­pa­pers. More than 100 peo­ple at­tended his fu­neral at the Jew­ish ceme­tery in Hamburg-​Ohlsdorf, most of them SPD party mem­bers bear­ing a red and black flag and sev­eral wreaths dec­o­rated with red bows. The pall­bear­ers were Jew­ish, and the fu­neral ser­vice was held in ac­cor­dance with Jew­ish rite. De­spite his decades of ser­vice to Ham­burg’s labor move­ment, Berkowitz Kohn largely fell into obliv­ion. His de­scen­dants con­tin­ued his work, how­ever. His grand­son, Rein­hard Kohn, after years of being per­se­cuted and op­pressed by the Na­tional So­cial­ists, not only be­came Sen­ate Pres­i­dent of Ham­burg after 1945, but, being a long-​standing mem­ber of the SPD, he also was ap­pointed deputy chief jus­tice of the Higher So­cial Court.

Joseph Berkowitz Kohn’s mem­oirs rep­re­sent a re­mark­able doc­u­ment for Ham­burg’s Jew­ish his­tory. His life par­a­dig­mat­i­cally re­flects the mi­gra­tion of east­ern Eu­ro­pean Jews to Ham­burg and their fre­quent ac­tivism in So­cial Democ­racy, labor unions, and co­op­er­a­tives dur­ing the last third of the 19th cen­tury.
