Henri Azariah Abraham (12 July 1868–22 December 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 executed at Auschwitz during the Holocaust.
