Proficiency Testing as a Tool for Confirming the Validation / Verification of Measurement Methods
In September of this year, the 120th anniversary of the birth of Maria Semenovna Schreiber, co-author of the outstanding physicist-chemist Nikolai Arkadievich Izmailov on the famous article of 1938, from which the history of thin-layer chromatography is started. The biography and heritage of N. A. Izmailov have been studied quite deeply, unlike M. S. Schreiber. Little is known about her, besides the fact that she did her scientific work in chromatography when she was a graduate student and worked under the supervision of N. A. Izmailov. Meanwhile, Maria Semenovna Schreiber (1904–1992) is the world's first woman to make a discovery in chromatography. In 1938, N. A. Izmailov and M. S. Schreiber came up with a new chromatography method, which was later called thin-layer chromatography (TLC). The article presents for the first time* a biography of Schreiber, as well as some of the events and people that may have served as the source of the two scientists' interest in chromatography.
