Stefanie Horovitz – the woman behind the isotope
Overlooked by history, murdered by the Nazis: the forgotten story of a talented chemist who helped prove the existence of isotopes
Stephanie Horovitz’s murder at the Treblinka extermination camp in occupied Poland at the hands of the Nazis was the final tragic turn in the life of a meticulous and talented experimentalist, destined to be overlooked by history. Her careful extractions and measurements confirmed the existence of isotopes, a finding that had huge implications to chemists working in the early 20th century, and still resonates today.
