Biographical/Historical
Description: Epstein was born in Poland. His family moved to Canada when he was seven. After his university years, Epstein worked for the Canadian Atomic Energy Project, where he was introduced to mass spectrometry by Harry Thode. Later, at the University of Chicago working with Harold Urey, Epstein became more involved in his pioneering work in isotopic geochemistry. He is known for his studies of the relative proportions of the stable isotopes of several elements. By analyzing the proportions of the different isotopes of hydrogen and carbon in meteorites, Epstein verified that they contained preserved organic compounds which were not only extraterrestrial in origin, but also compounds that were originally formed in interstellar space.
