Recent developments and additions to the site.
- As of 23 Jul 2023, based on new evidence a major change has been made to the assignment of the ancestors of Markus Cassirer. In particular, Markus Cassirer is no longer believed to have descended from Moses ben Loebel Cassirer (1768-1837) but rather from his first cousin Moses ('Mausche') Cassirer of Bujakow. An explanation of why this is required by the evidence is presented here Cassirer Ancestry Reconsidered and the family tree has correspondingly been adjusted to take account of it. The most important impact is that it brings together two previously difficult to connect parts of the Cassirer extended family. Key documents in support of this are available here.
- As of 25 December 2021 this site has now moved to meta-studies.net I have taken the opportunity to fix up some broken links and move the whole thing to a new server. It may take a while for Google to catch up, but the content is all still here!
- Site under reconstruction. It was time to reorganise this site which had grown like Topsy from 2004 when it was first established. The new site has been built using a database (Pm Wiki php database for the technically minded). The pages of the old site have either been recreated, or are now displayed within the framework of this new structure.
- I have purchased the domain cassirer.info. It is now possible to refer to some specific Cassirer locations in the site as follows: http://cassirer.info, http://ernst.cassirer.info, http://paul.cassirer.info, http://bruno.cassirer.info, http://richard.cassirer.info. Other links can be added. Let me know if you think any would be particularly useful.
- A Research in Progress section has now been added to the site in each family cluster. This is a nice place to piece together scattered bits of information as they come in.
- The London Reunion 2012 A highly successful reunion of Cassirer relatives was held in London in October 2012. Photos and other details including a free down-loadable book of the event. Arising out of this we now have:
- An Additional album of documents from Ernest Cassirer has been added relating to Lydia Cassirer, Rudolph Cassirer (including a letter from Albert Einstein) and the Nazi certificates of good conduct and lift of restraint required for Johanna Baron nee Cassirer to leave Germany.
- An album of documents associated with the Preston family has been added. Julie Cassirer married Otto Bondy (owner of the Cable Factory in Vienna). Their children Toni Bondy married Ernst Cassirer, whilst Walter Bondy, a well known painter, became part of the Berlin Secession. Daughter Martha Bondy married Oskar Pollak (sadly both victims of the Shoah).
- Irene Sychrava album. Irene Sychrava brought a wonderful collection of family photos, many of them identified, to the London reunion. She also generously agreed to lend them so they could be copied and put up on the website. Photos from the Ernst and Toni Cassirer, and Bondy lines and dinner menus and postcards including to the Geheebs can be found here.
- One family: Two lines. The Serck-Hanssen and Goerke Family Genealogy - Some real progress has been made in tracing the way in which the Marianne Serck-Hanssen and Johanna Goerke lines connect with the line of Cassirers stretching down from Marcus Cassirer.
- The work done for One family: Two lines leads naturally to a series of questions about the origins of the Cassirer family. How and where was the name coined? What of the other Cassirer descendants who were born but of whom we have yet to find information? And how did the Cassirer family move geographically and socially to become so well-known and frankly financially well endowed? Work on this can now be found centred on the Research in Progress section. This work includes:
- A tentative identification of further Cassirer relatives who lived in Oberglogau and quite a bit more now on Cassirers who we know of and may or may not be relatives.
- A set of documents related to Other Cassirer Descendants which has been added. This includes descendants of the brothers and sisters of Markus Cassirer and a generation further back, from the children of Loebel Moses Cassirer (1738-1809).
- An on-going analysis of the development and geographic movement of the Cassirer family with particular emphasis on their time in Bujakow where Loebel Moses Cassirer, possibly a "court jew" at the Grafen (estate of a nobel person), is believed to have first coined the name "Cassirer".
- Additional information uncovered on possible connections in Bujakow.
- Various other Cassirer "facts and snippets".
- The list of family victims of the Shoah (Holocaust) has now been brought up to date in relation to current available knowledge. This is now supplemented with a list of other Cassirers - some of whom are discussed above - not yet firmly identified with this family, who were victims of the Shoah.
- The Czech government has opened up death records from Theresienstadt Concentration Camp which may now be retrieved on line. Death certificates are now shown on this site for Lucie Lasker, Otto Steinitz, Dr David Königsberger and his wife Toni (nee Cassirer).
- For Isidor Cassirer descendants (including the Falk line, and Ernest Cassirer) the ancestors on the maternal side (Cecilie Sommerguth) are now traced back to 1720 bringing in many more relatives.
- Kabelwerk Dr. Cassirer Berlin-Spandau plans from 1928 reproduced here.
- The family tree has now been updated within the Cohen family cluster with records of more than 1000 people merged in providing either new entries or additional facts. Key to this has been the extensive genealogical work by Rod Corrie for whose generous contribution the site is greatly indebted.
- Some photo tributes have been added: Paul Cassirer Photo Album, Claude Cassirer (1921-2011), Some Cassirer Graves.
- A set of Schiffer family documents has been added. Since Emilie Schiffer married Louis Cassirer, and Rosalie Cassirer's daughter Margarethe Goldstein married Georg Schiffer, this family had a strong and early connection with the Cassirers. Sadly includes records of Else Schiffer (nee Knopf) victim of the Shoah (Holocaust).
- New information on The Julius Cassirer descendants and the stolen Pissaro painting including a highly informative article by Melissa Müller.
- In February 2014 a set of Cassirer documents was put on line as Papers of the Cassirer-Tietz Family, 1879-1983 by the Leo Baeck Institute. 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. [Caution should be exercised in relation to the genealogy provided as it seems to replicate the apparent misconception first published by Harry Nutt in his book "Bruno Cassirer" that the mother of Markus Cassirer was Eva Fischer whereas the evidence points to her being Pesel bat Salomon Friedländer. This arises from the fact that there were two Moses Cassirers living in close proximity (see elsewhere in this site).]
- In February 2020 this site is being moved to a new vps server.
- In March 2021 a new section has been created preparing for the Cassirer Reunion to be held in 2022.
