Henri Abraham (1868–1943) was a French physicist who made important contributions to the science of radio waves. He performed some of the first measurements of the propagation velocity of radio waves, helped develop France's first triode vacuum tube, and with Eugene Bloch invented the astable multivibrator. He was murdered at Auschwitz during the Holocaust. Source: Wikipedia (en)
