Günter Schmahl (26 March 1936 – 14 August 2018)[1][2] was a German physicist, professor at the University of Göttingen and a pioneer of X-ray microscopy.

The main focus of Schmahl's work, and his most important achievement, was the development of full-field soft X-ray microscopy. He was one of the first to recognize the potential of this method and to identify and follow the technological approach of using zone plates as lenses in such a microscope.[3][P 1][P 2] Schmahl and his colleagues further developed the technique until it was ready for application in two- and three-dimensional imaging of biological samples.[4][P 3][P 4][P 5][P 6]

Schmahl founded the Institute for X-ray Physics at the University of Göttingen and headed it until his retirement in 2002.[5] He was also one of the founders and the first organizer of the International Conference for X-ray Microscopy, which has been held every three years since 1983 and biennially since 2008.[6]
