Heinrich Graf von Lehndorff-Steinort

Heinrich Ahasverus Graf von Lehndorff-Steinort (22 June 1909 – 4 September 1944) was an East Prussian junker and aristocrat who became a member of the 20 July plot to assassinate Adolf Hitler.

After the Second World War broke out, he was first deployed in Poland, and later, as a reserve lieutenant, posted to General Fedor von Bock's staff, who later became supreme commander of Army Group Centre (Heeresgruppe Mitte).

As a first lieutenant in the reserves, Lehndorff was deployed as liaison officer to Defence District I (East Prussia) in Königsberg (today Kaliningrad, Russia).

Along with Kurt Hahn, Gerhard Knaak, Hans Otto Erdmann and Max Ulrich von Drechsel he was sentenced to death by the Volksgerichtshof under Günther Nebelung on 4 September 1944.

His wife Gottliebe née Gräfin von Kalnein (1913–1993)[3] and their four daughters (Marie Eleanore [who married Wieland Wagner's son, Wolf Siegfried],[4] Vera, Gabriele, and Katharina) spent the remainder of the war confined to concentration camps.
