Richard Glazar (November 29, 1920 – December 20, 1997) was a Czech-Jewish inmate of the Treblinka extermination camp in German-occupied Poland during the Holocaust.

One of a small group of survivors of the camp's prisoner revolt in August 1943, Glazar described his experiences in an autobiographical book, Trap with a Green Fence: Survival in Treblinka (1992).

[2] His parents divorced in 1932, and his mother married a wealthy leather merchant, Quido Bergmann, who already had two children, Karel and Adolf.

[1] Glazar's father died of pneumonia in the Soviet Union, to which he had escaped from the Nisko reservation in the General Government of occupied Poland; some 1,100 Czech Jews had been deported there by the Nazis in 1939.

[citation needed] Glazar's mother survived both Auschwitz and Bergen-Belsen, and was the only member of his family left when he returned to Prague in 1945.

On September 12, 1942, he was transported to the Nazi concentration camp or ghetto at Theresienstadt (previously the fortified town of Terezin, located 35 miles north of Prague).

Following the German occupation of the rest of Czechoslovakia on March 15, 1939, Theresienstadt became a holding area for transports to other concentration camps, such as Auschwitz.

When Glazar moved to Switzerland after the Prague Spring, his memoir was published in full in German as Die Falle mit dem grünen Zaun: Überleben in Treblinka (1992).

He described in his book the packing of victims' clothes for shipment to Germany, and how the gold from teeth was extracted and, together with coins and jewelry, added to the German loot.

Food brought by the victims helped sustain both the SS and the Ukrainian guards, along with inmates who would steal it at the unloading ramp.

The Sonderkommando had virtually no food, which made the Jewish inmates realize that their lives depended on the transports arriving regularly.

While on the run, they were arrested by a forester, but managed to convince him that they were Czechs working for "Organisation Todt" (a Nazi construction and engineering group in Poland).

Glazar helped Michael Peters, the founder of the Aktion Reinhard Camps (a network of private Holocaust researchers), build a model of Treblinka.
