About Dr Fickelberg
Dr Fickelburg and a Jewish nurse were among those gassed in a truck from Lodz to Chelmno.
'The Chronicle of the Lodz Ghetto' recorded with precision the number of deportees: 5,353 men and 5750 women.
The Chronicle knew only that they had been resettled, not that they had been deported to Chelmno and gassed.
