Towards the end of November 1941, the Nazi authorities began to deport the Jews of Bohemia and Moravia (the Protectorate) to the fortress city of Theresienstadt, about 60 km north of Prague. In June 1942 , deportations of Jews from Germany and the Netherlands to Theresienstadt began.
According to the Theresienstadt ghetto listings, a transport marked XIX/7 Ez arrived in Theresienstadt on 5 October 1944. This transport was listed as Ez, which were the German initials for special transport of individuals (Einzelreisende Sondertransport). The Roman numeral XIX referred to transports from of Usti nad Labem (Aussig) and the vicinity (Sudetenland region),
The only person listed on this transport was Gerson Müller, who was born 11 days prior near Litomerice (Leitmeritz). According to personal file no. 325 in the Beit Theresienstadt archives, Gerson Müller was born in the small fortress (Kleine Festung) in Theresienstadt. His mother, Ruzena Müllerova, was deported with her eldest son Petr from Praha (Prague) to Theresienstadt on 14 December 1941 on transport M. Apparently, she had been employed in German households outside the ghetto, and was imprisoned in the small fortress for attempting to pass information about the ghetto to the outside world. After giving birth to Gerson on 24 September 1944, the infant was sent to Theresienstadt, where his brother was still imprisoned.
Based on the above information, it may be presumed that no actual transport took place. Since a a transport number identified every inmate of the ghetto, it would seem that transport XIX/7 Ez on 5 October 1944 was a fictitious transport created out of bureaucratic necessity.
Ruzena Müllerova and her two children managed to survive her imprisonment and the harsh conditions of the ghetto until the end of the war. However, the father of the family, Hanus Müller, was sent from Theresienstadt to Auschwitz-Birkenau on 28 September 1944, several days after the birth of his son, and was in all likelihood murdered upon arrival.
