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.[1][2][3] The team determined the sample to be over 1,725,000,000 years old.[4][5][6]

Monsanto

[edit]

In 1934, Editha Karl-Kroupa Kroupa, who was an Austrian research chemist worked with a new method of microchemical analysis in the laboratory of Prof. A. Franke at the University of Vienna, analyzed a sample of radioactive rock from near Winnipeg, Canada. | [7] Kroupa emigrated to the United States in the 1950s. According to US Customs records, on 3 June 1953, Editha Karl-Kroupa, age 43 and Hugo Karl, age 43, arrived at New York City, New York, and listed a local address as the Hotel Almac on Broadway and 71st Street in New York City. The couple embarked from Bremerhaven, Germany on 26 May 1953 aboard the USNS General Alexander M. Patch (T-AP-122) and traveled in Cabin Class. They arrived in New York on 3 June 1953 and presented Austrian passports to US Customs officials. The couple traveled with 6 pieces of baggage.[8]

Kroupa worked as a chemist in the Inorganic Chemicals Research Division for the Monsanto Company, in Dayton, Ohio, where her research focused on phosphates.[9][10][11][12]
