First anniversary commemorative pin for the May 12, 1945, liberation of Theresienstadt concentration camp acquired by Frank Meissner, whose family had been imprisoned in the ghetto/labor camp in Czechoslovakia. On September 16, 1945, there was a public ceremonial burial for 601 victims exhumed from six mass grave sites uncovered at the Small Fortress. From 1940-1945, the Small Fortress served as the prison at the Terezin camp. At the age of 16, Frank left Trest, Czechoslovakia, in 1939 to avoid the increasingly harsh Nazi persecutions of Jews. He went to Denmark with Youth Aliyah to attend agricultural school. In fall 1943, when the Germans decided to deport all Jews from Denmark, Frank was smuggled on a fishing boat to Sweden. During his exile, he received weekly letters from his family, even after their deportation to Theresienstadt ghetto. The letters stopped in 1943. In the fall of 1944, Frank learned that his family had been sent to Auschwitz concentration camp. He joined the Czech army-in-exile in Great Britain. After the war ended in May 1945, Frank returned to Czechoslovakia searching for his family, but he found no survivors.
