!!!Key Cassirer Documents
* RecentVitalDocs - Recently recovered vital documents enabling significant uncertainties about the early history of the Cassirers to be clarified and reset.

* [[http://meta-studies.net/genealogy/ZDocs/Berlin2002/index.html|Berlin Reunion 2002.]]  In 2002 a reunion was held in Berlin for relatives of the Cassirers. It was by all accounts a great success. Pictures from the reunion are show here.

*[[Family victims of the Holocaust]]

*LoebelMosesCassirer - Residence Permit of Loebel Moses Cassirer and other documents and marriage certificate signed by LoebelMosesCassirer 1796.

*[[Main.CassirerStiftungMetatdata|Cassirer Family Trust "Stiftung" documents 1914-1931]]
 
*[[http://meta-studies.net/genealogy/ZDocs/Cassirer/Kriegszt_1918/index.html|"Deutsche Kriegszeitung" 17 March 1918 - Original in German]]; [[http://meta-studies.net/genealogy/ZDocs/Cassirer/Kriegszt_1918/War_Paper.htm|Translation into English.]] A mock 'war newspaper' produced by the Cassirer family on 17 March 1918 as an amusing account of family news and the war.

*[[CassirerAnecdoteBooklet|Cassirer Anecdote Booklet]] 18 October 1937 -Original in German; [[CassirerAnecdoteBookletTrns|Translation into English.]]  This booklet, in German, edited by ToniCassirer, was produced for the occasion of MaxCassirer 's 80th birthday. It contains many amusing anecdotes and is the most detailed original account of the lives of the Cassirers in the late 19th and early 20th century.

*[[http://meta-studies.net/genealogy/ZDocs/Cassirer/Cassirer_Address_Book_31/A01.html|Cassirer page: Berlin Jewish Address Book 1931.]] This is a page of the Berlin Jewish Address Book in 1931 showing the addresses of a number of members of the Cassirer family at that time in Berlin.

*[[http://meta-studies.net/genealogy/ZDocs/Fident/Identr.html|Cassirer Group Photographs.]] Various group photographs taken at weddings and other Cassirer occasions between 1900 and 1937, some of whom are identified and some of whom remain to be identified. Your assistance in identifications would be appreciated.  Also begging for identification is this picture of a [[Cassirer residence in Breslau]].

*[[Main.CassirerFalkMiscellaneousAlbum|Album of miscellaneous additional information on the Cassirer and Falk families.]] There is quite a bit of information which is progressively uncovered about the Cassirer and Falk families. There is more diverse detail on everything from paintings owned by PaulCassirer, to the [[Main.KabelwerkDr.CassirerBerlin-Spandau|Cassirer Cable Factory]]. Some of it is information provided by researchers such as Adalbert Saurma who have provided translation and research for this site. This album is the place where this information was initially progressively collected. It is no cross-referenced into the [[Cassirer.Families|Families and Individual pages]] in this Document Collection.

*[[http://digifindingaids.cjh.org/?pID=482057|Papers of the Cassirer-Tietz Family, 1879-1983]].  In February 2014 the Leo Baeck Institute placed in digitised form its records of the papers of the Cassirer-Tietz Family. This replicates a number of documents already on this site but also contains a wealth of additional documentation, including attempts at preparing a family genealogy.  [Interestingly the genealogy supports very recent evidence, and the genealogy first published by Harry Nutt in his book "Bruno Cassirer" that the mother of [[Main.MarkusCassirer|Markus Cassirer]] was Eva Fischer.  This now appears to be correct and should replace prior assignments  of his mother as Pesel bat Salomon Friedländer.  This arises from the fact that there were two Moses Cassirers  (quite probably first cousins) living in close proximity (see [[Main.VariousLeadsFromOldGermanResources#moses2|elsewhere in this site]]).]  The documents are housed at the Center for Jewish History, 15 West 16th Street New York, N.Y. 10011, [[http://www.lbi.org]].

 
!!!Descendant Albums
Albums of documents and photos have been created  relating to the following Cassirer ancestors: 

*EduardCassirer Descendants - [[Main.BanoFamilyAlbumOfCassirerDocuments1885-1939|album]] including related photographs, messages, references, menus, obituaries and celebratory poems 1885-1939.
**ErnstCassirer including [[http://meta-studies.net/genealogy/ZDocs/Webp/My_Grandfather_ErnstC.htm|reflections]] by his grandson, PeterCassirer.
**IreneSychrava - [[http://meta-studies.net/pmg/index.php?n=Main.IreneSychravaAlbum|album]] including photos, postcards and menus.

* IsidorCassirer Descendants including:
**IsidorCassirer and LydiaCassirer - [[IsidorCassirer&LydiaCassirerdocuments|document set]], including telegram from von Hindenberg, Honour Cross certificate presented to Lydia, marriage certificate, and ironically Honour Cross in the name of Hitler to RudolphCassirer 
**[[ErnestCassireralbum|Album]] of documents from ErnestCassirer including Mourning Book and war records of their son RudolphCassirer.  
**[[Main.ErnestCassirerAlbum2|Additional album of documents]] from ErnestCassirer relating to LydiaCassirer, RudolphCassirer (including a letter from AlbertEinstein to RudolphCassirer, about the status of Refugees in which Einstein says that he had written to President Roosevelt, and suggests that anyone who had influential contacts urge them to also do what they could). Included also are the Nazi certificates of good conduct and lift of restraint required for JohannaBaron nee Cassirer to leave Germany.
**[[MiriamLaparnealbum|Album]] of Cassirer Photographs and Anecdotes ~1890-2005 from the late MiriamCassirerLaparne.

* JulieCassirer married OttoBondy (owner of the [[Main.DasKabelwerk|Cable Factory in Vienna]]).   Their children ToniBondy married ErnstCassirer, whilst WalterBondy, a well known painter, became part of the Berlin Secession. Daughter MarthaBondy married OskarPollak (sadly both victims of the Shoah). This is an [[Main.PollakAlbum|album of documents]] associated with this line.

* JuliusCassirer Descendants - including an [[RFBrunoCassirerAlbum|album]] of documents on BrunoCassirer by Regina Pfennig.  The story of Julius's son Fritz (FriedrichLeopoldCassirer)  and their descendants is part captured here - in [[The stolen Pissaro painting Saga]] - which recounts the saga of the struggle by ClaudeCassirer for return of a painting stolen by the Nazis from Friedrich's wife LillyDispecker. The struggle continues through Claude's son DavidCassirer.
 
* MartinCassirer Descendants - including
**A [[BenBanoAlbum|moving account of the life of SusanneBano]], and her grandmother LucieLasker, who lost her life in Auschwitz: by Susanne's son, BenBano.
**The [[Lucy Lasker and Willi Bodlaender|Lucy Lasker and Willi Bodlaender  album]]. The last year of LucieLasker was intimately tied to the fate of a friend WilliBodlaender, who whilst not a Cassirer shared with her, via a postcard, their last communications before their murder by the Nazis.  This album contains material honouring both of them and their living relatives.
 
* SalomonCassirer Descendants - with an [[SalomonCassirerCollection|album]] including the Marriage Certificate of [[Main.KaetheCassirer|Käthe Cassirer]] and Dr. PaulHerrmann.

* LouisCassirer Descendants - including an [[ReinholdCassirerInterview|interview]] with ReinholdCassirer
**[[Main.PaulCassirerPhotos| Photos]] of PaulCassirer - from funeral, Berlin Secession, and gallery.
**[[Main.SchifferRecords|Schiffer family documents]].  Since EmilieSchiffer married LouisCassirer, and RosalieCassirer's daughter MargaretheGoldstein married GeorgSchiffer, this family had a strong and early connection with the Cassirers. Sadly includes records of [[Main.ElseKnopf|Else Schiffer (nee Knopf)]] victim of the Shoah (Holocaust).

*OtherCassirerDescendants.  The above are the descendants of MarkusCassirer. This section is devoted to those identified amongst the many other descendants, including the brothers and sisters of MarkusCassirer and a generation further back, from the children of LoebelMosesCassirer (1738-1809).

!!!Speculations and Queries
Material in this section is particularly speculative, drawing as it does on secondary material (often found by web-search) and with suggestive but far from conclusive connections suggested.  Please exercise care in utilising these observations noting that they are speculative if you ever cite them.  If you have information that would improve our knowledge, as always, this will be very welcome.

*[[UnidentifiedCassirers|References to Cassirers who may be related]] appearing in the historical record who may or may not be connected to this family tree. Any help you can give in establishing such connections would be appreciated.  Included are those of these who were [[Main.FamilyVictimsShoah|victims of the Holocaust]]

*See also some old [[http://meta-studies.net/genealogy/ZDocs/Fident/Identr.html|Cassirer family group photographs]].  Help with identifying these ancestors would be greatly appreciated.

*There is also [[Main.VariousLeadsFromOldGermanResources|a lively "living" discussion of the early development of the Cassirer family]] before and after the name "Cassirer" was coined, and the factors in their social and economic environment which caused them to develop as they did.
