Albert Sauer (17 August 1898, Misdroy – 3 May 1945, Falkensee) was a Nazi German commandant of Mauthausen-Gusen concentration camp.
[2] Between 1 August 1937 and mid-1938, Sauer was second Schutzhaftlagerführer in Sachsenhausen concentration camp and thus belonged to "Wachtruppe Brandenburg".
[1] In the period between 1 August 1938 and 1 April 1939, he officially acted as commandant of the then-temporary quarry Wienergraben, so named because of the Wienergraben Valley in which it was located, of Granitwerke Mauthausen, which relied on slave labor from the subcamps of Mauthausen-Gusen.
[3] In the period of 1941–1942, he had an official position in the RKFDV (Reichskommissar für die Festigung deutschen Volkstums; Reich Commissioner for the Consolidation of German Nationhood).
Later, he was temporarily the commandant of Kaiserwald concentration camp which was vacated in July 1944, by execution and deportation of inmates.
