The world doesn't hear very much about Albert Speer. I doubt many of today's kids would recognize the name. (I've known adults who have to stretch to identify Hitler.) Partly, I think, this is because he was a civilian and not given to wearing snappy uniforms and stomping around in breeches and boots.
In 1925, handsome young Albert Speer and his wife were in Berlin, a cosmopolitan city, and Speer became a student of architecture at the university, although he would have preferred studying maths.
When the German economy collapsed in the 1930s and Hitler's radical ideas were becoming popular, Speer first heard Hitler speak in the university's atrium, and he was seduced by Hitler's smooth delivery and his knowledge of art. (Hitler had dabbled in painting.) This wasn't the Hitler of the Nuremberg rallies, raving and shouting. It was Hitler the philosopher and he won Speer over.
Speer joined the Nazi party and worked for Hitler as an architect and a stage designer, as it were. He provided the background for the political speeches. In 1934 the compliant Speer was appointed chief architect for the Reich and designed the stadiums for the Nuremberg rally and the 1936 Olympics. In 1942 he became Minister of Armaments.
There is no denying that he was about as good a manager as any dictator could have hoped for, even though his real love remained architecture. If Hitler asked for a given number of weapons systems, Speer could provide double the number, even after the Reich began its collapse. Even in mid-1944 Speer was exceeding his quota of airplanes and large weapons.
Speer was the only defendant at Nuremberg to admit his responsibility and spent twenty years in Spandau Prison. He was released in 1967 and died in 1981, after having written the usual self-serving biography.
The program was evidently made in and for modern Germany and is a pastiche of stills, movie footage, and a few witnesses who provide talking heads. It's extremely informative and hard on Speer, probably with reason.
