Ludwig Gehre (5 October 1895 – 9 April 1945) was an officer and resistance fighter involved in the preparation of an assassination attempt against Adolf Hitler.
By March 1943, Gehre was privy to the preparations under Henning von Tresckow to assassinate Hitler.
In January 1944, Helmuth James Graf von Moltke was arrested, and in March 1944 Gehre was also taken by the Gestapo.
After the failed 20 July 1944 assassination attempt to kill Hitler, the search for Gehre intensified.
From there, he was put onto a transport of SS special detainees and on 5 April incarcerated in the Flossenbürg concentration camp.
