Albert Speer was a Nazi architect and engineer who played a prominent role in Hitler's regime during World War II. Known for his efficient management techniques and construction innovations, he was often described as a "master planner" or a "brilliant organizer". However, after the war, Speer was tried and convicted for war crimes, leading to the use of more negative synonyms like "war criminal", "Nazi collaborator" or "Holocaust enabler". Despite his later condemnation, his initial reputation as an effective administrator has led to more neutral phrases like "Hitler's architect" or "Third Reich's chief architect".
