Biographical Note

The Cassirer family originated in Breslau (now Wrocław, Poland) but by the early twentieth century many members had settled in Berlin. On October 28, 1890 eight family members founded the Marcus und Jeanette, Siegfried und Henriette Cassirer'sche Familien-Stiftung.

The family included many individuals who became well-known in their fields. Some of its prominent members included Hugo Cassirer, a chemist who founded the firm Dr. Cassirer & Co. with his father Louis Cassirer in Berlin in 1896; the philosopher Ernst Cassirer, who taught at the universities of Berlin, Hamburg, Oxford, Yale and Columbia, as well as elsewhere; the publisher Bruno Cassirer, who had his own publishing company begun in 1901; the publisher, author and art enthusiast Paul Cassirer; the philosopher Fritz. Cassirer; the neurologist Richard Cassirer; and the astronomer Eva Cassirer.

Most family members emigrated from Germany following the rise of Nazism, eventually leaving the family spread throughout the world, including the United States, the United Kingdom, France, Denmark, Switzerland, and South Africa. A few family members returned to Germany.

Edith Grünfeld (great-granddaughter of Marcus and Jeanette Cassirer) married the businessman Georg Tietz, the eldest son of Oscar Tietz, founder of the German department store known today as Hertie. In 1936 they immigrated to the United States with their two children by way of Lichtenstein, Yugoslavia and Cuba, arriving in 1941.

This series is in English and German.
0.3 linear feet.


Scope and Content:

Series I contains of the genealogical research of Edith Tietz, including several folders of research correspondence in addition to copies of family trees and a notebook of names.

More than half of this series consists of correspondence between Edith Tietz and numerous members of the Cassirer, Bondy, and related families. These letters include discussion of family connections and reminiscences of family members no longer alive along with friendly greetings and updates on family news. Some letters include brief narratives of family history or sketches of parts of family trees. The second folder of the series, which focuses on research into a branch of the interrelation of the Cassirer, Bondy, and Waller Families, includes a few official documents and obituaries for Robert Waller, Max Waller, and Otto Bondy. Most of the genealogical research is centered in the folders of correspondence organized by family and the loose correspondence; the latter was not previously organized. Greeting cards and the letters of Irmgard Foerg are primarily friendly greetings, with little mention of Edith Tietz's research.

The final three folders of this series hold its family trees and notes on research. The first of these shows the family branches from the late 1800s through the 1970s, while the folder on Moses Cassirer and his descendants displays that branch of the family from the 1700s through the 1800s. The most frequently-occurring surnames in the trees include the Cassirer, Stein, Goldstein, Glaser, Gruenfeld, Tietz, and Bondy families. The final folder contains a notebook of family members, organized alphabetically by surname. Women's names are ordered by their married surname. Each entry includes biographical dates and names of spouses.
