Edith Kroupa (1910–1991) was a research chemist who utilized microchemical analysis in the laboratory of Professor A. Franke at the University of Vienna. In 1930, Kroupa and Friedrich Hecht analyzed a sample of radioactive rock from the Huron Claim, Manitoba near Winnipeg, Manitoba, Canada. The team determined the sample to be over 1,725,000,000 years old. Also in 1930, Kroupa and her colleague Friedrich Hecht had discovered triple-weight hydrogen, also known as tritium.
