Some sources state that Czaplicka was operated on for appendicitis at St Bartholomew's Hospital by Józef Handelsman, but Handelsman was a psychiatrist, not a surgeon, and never worked at St Bartholomew's Hospital. The confusion appears to stem from the fact that Czaplicka was under the psychiatric care of Handelsman at the time she was admitted to St Bartholomew's. Her operation at the hospital was in fact carried out by Mr William Bruce Clarke, as noted in the hospital's Female Admission Register, 1908-1913 (see online catalogue entry for this item here).
