station at Treblinka. Rajzman said, "When the persons descended from the trains, they really had the impression that they were at a very good station from where they could go to Suwalki, Vienna, Grodno, or other cities." Rajzman also stated that Franz was responsible for the death of renowned psychologist Sigmund Freud's sister. At first, Kurt Franz supervised work commandos, the unloading of transports, and the transfer of Jews from the undressing rooms to the gas chambers. Franz had a baby-like face, and for this he was nicknamed "Lalke" ("doll" in Yiddish) by the prisoners. But Franz's appearance belied his true nature. He was the dominant overseer in day-to-day interactions with prisoners in Treblinka, and he became the most feared man at Treblinka for the cruelty which he visited upon them. Facts prove otherwise. Despite visible damage to the camp during the revolt, the gas chambers were left intact and the killing of Polish Jews under Kurt Franz continued, albeit at a reduced speed with only ten boxcars "processed" at a time until the last transport of victims arrived on 19 August with 7,600 survivors of the Białystok Ghetto Uprising. Franz followed Globocnik to Trieste in November 1943. Barry the dog Franz was known for being unusually cruel and sadistic. He often made his rounds of the camp riding a horse, and would take his St. Bernard dog, Barry, along with him. Barry was trained to follow Franz's command, which was usually to bite the genitalia or buttocks of prisoners. Barry's first owner was Paul Groth, an SS officer at Sobibor. Depending on his mood, Franz would set the dog on inmates who for some reason had attracted his attention. The command to which the dog responded was, "Man, grab that dog!" ()—by "man", Franz meant the dog Barry, and the "dog" was the human inmate whom Barry was supposed to attack, in an effort at dehumanization. Barry would bite his victim wherever he could catch him. The dog was the size of a calf so that, unlike smaller dogs, his shoulders would reach to the buttocks and abdomen of a man of average size. For this reason, he frequently bit his victims in the buttocks, in the abdomen and often, in the case of male inmates, in the genitals, sometimes partially biting them off. When the inmate was not very strong, the dog could knock him to the ground
