TadeuszBanachiewicz (1882in Warsaw -1954inCracow) was outstanding Polish astronomer, geodesistand mathematician. His activity strongly influenced Polish astronomy during between war period and after WWII. He invented a theory of "cracovians" (a special kind of matrix algebra) which brought him international recognition. This theory allowed to obtain easily several astronomical, geodesic, mechanical and mathematical problems. This as well as other achievements were widely known all of the world. He was a professor at the Jagiellonian University in Cracow and director of the University Observatory for 35 years (1919–1954). Banachiewicz c.1910
In 1915 TadeuszBanachiewiczmovedfrom Kazan to the AstronomicalObservatory in Yuryev University (edict from September, 5, 1915),where he took over the vacant post of astronomer -younger assistant. Thesis“ Three essays on refraction theory”. On December , 11, 1915 he became a privat – docent of the Yuryev Univ. Magister degree thesis: “ On the Gauss equation sin (z-q) =m sin4z, where z is close to q”. The public defense took place on September, 12, 1917 Reviewers: Konstantin Dormidontovich Pokrovsky(1868–1944). Leonid SamuilovichLeybenzon (1879 –1951) Erich Schoenberg (1882–1965)

This is the end of 66 days directorship of Banachiewich. The Yuryev University earlier was partially transferred to Voronezh. Banachiewicz was regarded as professor there.
