Klaus Biemann (November 2, 1926 – June 2, 2016)[3][4] was an Austrian-American professor of chemistry at the Massachusetts Institute of Technology.
He was drafted into the Wehrmacht during the final months of World War II and was sent to aid the divisions fighting against Allied forces then retreating before the Soviet Army on the Eastern Front.
[10] Two years later with the assistance of Büchi, he was offered a faculty position at MIT in the analytical chemistry division where he turned his focus to peptide analysis and sequencing.
Before embarking on his new research, however, Biemann decided to buy a mass spectrometer and use it to study peptides instead.
[10] He partnered on the NASA Viking mission project to Mars which failed to detect organic matter on its the surface in 1976.
