Edie Lehnsherr was the mother of Magneto.
Because of their Jewish heritage, the Lehnsherr family was transported to the Auschwitz concentration camp in Nazi-occupied Poland in 1944. Edie tried to look for her son when they were seperated, but was pushed away with her husband, Jakob.
When Erik was brought before Klaus Schmidt, he was told to move the coin with his magnetic powers. After he couldn't, Schmidt sent his mother in and threatened that after the count of three, he would kill her. After failing to move the coin, Edie was shot dead, igniting Erik's powers.
