[4] In the same year, Dorodnitsyn passed the entry examination at the Novocherkassk Polytechnic Institute, with honors, but was denied enrollment based on his “non-proletarian origin”.

He immediately applied to, and was enrolled in, the Grozny Oil Technical School,[5] which was one of the first higher educational institutions teaching hydrocarbon-related subjects in Russia.

[8] Both these organizations created their own seismological task force, appointing Dorodnitsyn as their head and dispatching them to the Ural Mountains, Bashkortostan and Turkmenistan to conduct geological researches.

He completed his postgraduate studies at the Leningrad Main Geophysical Observatory from 1936 to 1938 under the supervision of Prof. Ilya Afanasievich Kibel, a member of the scientific school led by academician Nikolai Yevgrafovich Kochin, a leading Russian researcher in applied mathematics, particularly in the areas of fluid and gas mechanics.

He received his PhD and was promoted to the position of Senior Research Fellow in the Department of Dynamic Meteorology of the Leningrad Main Geophysical Observatory.

[10] In 1940, Dorodnitsyn entered a doctoral program led by academician Nikolai Yevgrafovich Kochin at the Institute of Mechanics of the USSR Academy of Sciences.

[12] Dorodnitsyn worked part time at the Leningrad branch of the Steklov Mathematical Institute as a leading research fellow and later as a department head.

[15] A substantial part of the presentations of Russian and foreign scientists on this conference aimed at original accomplishments in the fields marked by A.A. Dorodnicyn's fundamental contributions.
