The Bauer Sisters

Dagmar Nick, greatgranddaughter of Jenny Asch, has written a book Juedisches Wirken in Breslau [Sigmaringen:  Bergstadt Verlag, 1996] focussing primarily on Jenny and her husband, Dr. Sigismund Asch, who was famous in Breslau for his philanthropy, as a hero of the Revolution of 1848, and as a pioneer in public health.  There is also much information on Lina Morgenstern in the book, and somewhat less about the other sisters.

There is also a recent book Suppenlina, by Heinz Knobloch, [Berlin: Edition Hentrich, 1995] on Lina Morgenstern, and an historical novel Das Glueck Lina Morgenstern, by Wolfgang Lohmeyer, [Vienna:  Langen Mueller, 198x].

For important anniversary birthdays of her sisters [e. g. 70th], Lina Morgenstern wrote laudatory articles in the deutsche Hausfrauen Zeitung, which she edited.  I've translated these, and others, and they can be found on Paul Honigmann's web site.
