Executed members of the 20 July plot

Friedrich Olbricht (4 October 1888 – 21 July 1944) was a German general during World War II. He is known for being one of the plotters involved in the 20 July Plot, an attempt to assassinate Adolf Hitler in 1944.
Olbricht was a senior staff officer, with the rank of lieutenant general. He was secretly in contact with most of the leaders of the resistance. They briefed him on their various plots and he placed sympathetic officers in key positions. Olbricht quietly encouraged field commanders to support the resistance. By late 1943, his office was the centre of Resistance plotting, under Claus von Stauffenberg. Had the 20 July plot to assassinate Adolf Hitler been successful, Olbricht would have assumed the position of minister of war in a post-Nazi regime.

Adolf Reichwein (3 October 1898 – 20 October 1944) was a German educator, economist, and cultural policymaker for the SPD, who resisted the policies of Nazi Germany.

From 1938 he became involved with the anti-Nazi resistance, and was executed in 1944 for his role in the 20th July plot to overthrow Adolf Hitler's regime.
