- 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. [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).] The documents are housed at the Center for Jewish History, 15 West 16th Street New York, N.Y. 10011, http://www.lbi.org.

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 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 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.
- Recent Vital Docs - Recently recovered vital documents enabling significant uncertainties about the early history of the Cassirers to be clarified and reset.
- 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.
- Additional album of documents from Ernest Cassirer relating to Lydia Cassirer, Rudolph Cassirer (including a letter of recommendation from Albert Einstein) and the Nazi certificates of good conduct and lift of restraint required for Johanna Baron nee Cassirer to leave Germany.
- Additional album of documents from Ernest Cassirer relating to Lydia Cassirer, Rudolph Cassirer (including a letter from Albert Einstein to Rudolph Cassirer, 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 Johanna Baron nee Cassirer to leave Germany.
