«We once had an appointment for dinner at Bristol [probably in Berlin]. Sauerbruch, my father, Mrs. Rust, de Crinis and Mrs. de Crinis... She [Lili de Crinis] got up and ran towards Ms. S[auerbruch], hugged and kissed her and called out almost too loudly for me to understand: 'My dear Mrs. Sauerbruch, how pleased I am to see you!' Then she came back to the table with her arm in her arm and winked at me».
— from letter by Helmut G. friend of de Crinis, to W. Krüger, 1990s.
