Documents associated with this person:

Mother of Fräulein Trude Kaff, pupil of Schenker. From his diaries, it is clear that Mrs. Kaff, whom he characterizes as "the wife of a businessmann" (OJ 1/12, p. 311) was a source of irritation to Schenker. She lived in Brno (Brünn).

There was, as his diary attests, correspondence between Mrs. Kaff and Schenker, but not of it is known to survive.
