Gisela Schertling’s tonsilectomy
When she was 11 or 12 years old, Prof. Dr. Zanger in Jena took out her tonsils. On that occasion, they observed excitability and convulsions. Professor Zanger’s nurse [Note 1] told us immediately that we needed to particularly look after Gisela’s health, because her nervous system did not work right.
