There were two entries both for Estera Frajda Bitterman born 01/01/1924 with the same addresses listed. Born in the year 1924, it would make sense that Estera attending Gymnasium and High School for Girls.
There is a note associated with her information which reads: GEST 28.8.42 which I believe means she died in August 28th, 1942. I also believe she died in the Lodz Ghetto because there is no note of her being transported anywhere. However, I will continue my research in order to validate this claim.
I believe this student died in Sattler 7 on 28/8/1942 because on one of the listings the note reads: Sattler 7 GEST 28.8.42
We know from the other listing that Sattler 7 was one of the students addresses within the ghetto, and based on this note it seems likely that this is the location where she died.
