The Germans built the death camp in Treblinka in mid-1942 next to the nearby penal labor camp. It's first commandant was the medical doctor Irmfried Eberl. The first transport arrived on July 23, 1942 and contained Jews from the Warsaw ghetto; subsequent transports came from the territories of occupied Poland, Germany, Austria, France, Czechoslovakia and the USSR. According to historians' estimates, about 900,000 people died in Treblinka. Most of them - approx. 760 thousand. - came from Polish territories.
