In many sites and publications (for example, HERE), this man is said as Theodor Tolsdorff (3 November 1909 - 25 May 1978), a recipient of Brillanten zum Ritterkreuz des Eisernen Kreuzes with the last rank of Generalleutnant. In reality, he is actually Ritterkreuzträger Karl Frewer (21 July 1908 - 6 March 1945) who received the Ritterkreuz on 12 November 1943 as Major and Kommandeur I.Bataillon / Grenadier-Regiment 167 / 86.Infanterie-Division. The most obvious difference is that Frewer was alo a recipient of Nahkampfspange (visible in this picture), while Tolsdorff was never awarded the same medal.
