Answer:
Albert Speer was a German architect who was Minister of Armaments and War Production in Nazi Germany during World War II. Therefore, he was part of the leadership of the Nazi government, with which he had direct responsibility for the decisions of this regime, thus being largely responsible for the war crimes that Germany committed during World War II. In addition, since he was in charge of producing the armaments necessary to sustain the war, and designing new weapons developments capable of wreaking havoc on enemies, Speer had a fundamental role in the battle conditions of the war. For these reasons, Speer was sentenced to 20 years in prison during the Nuremberg Trials, which was appropriate given his participation in the Nazi regime.
