Re: Prysewiczuvna girls school in Lodz #lodz
The school was
Gimnazjum żeńskie Janiny Pryssewiczówny
located at ul. Sienkiewicza 35 (in the year 1923). (Pryssewiczowna's Girls Gimnasium)
In the year 1934 or 35 it was bought by Tadeusz and Janina Czapczyńscy,
(New name of the school was: Prywatne Gimnazjum i Liceum Janiny Czapczyńskiej located at ul.Narutowicza 58)
I looked at "Szukaj w archiwach" site and there are no records for Pryssewiczówna school, but there is a rich documentation for Czapczynski's school.
They are located in the Lódź Archive (Archiwum Państwowe w Łodzi)
It is possible that you will find something there for these individuals. Especially classroom diaries (dziennik lekcyjny) have many information about the students.
