Note of I.Kurchatov for M. Pervukhin, 'About Necessity to Demobilize V.M. Kelman'
In this document, the "father" of the first Soviet nuclear bomb, Igor Kurchatov, asks the chief of the Soviet ministry of energy, Pervukhin, to help demobilize the Ukranian physicist Veniamin Kelman, who was a fellow of UIPhT before the war. In this note Kurchatov writes about the high quality of the Ukrainian nuclear scientist and about his importance for the development of the Soviet nuclear program. This document once again demonstrates that Ukraine played a significant role in the Soviet military nuclear program.

Letter, Igor V. Kurchatov, Director of the Soviet Nuclear Program, to Lavrenti Beria
In this letter, physicist Igor V. Kurchatov, the scientific director of the Soviet nuclear project, writes to secret police chief Lavrenti Beria, whom Stalin had given principal responsibility for the atomic effort. Prodded by his own scientists and by intelligence reports of the secret Anglo-American atomic enterprise, Stalin had initiated a small-scale Soviet nuclear weapons program in late 1942-early 1943. But the level of support political leaders had given the project failed to satisfy Kurchatov, who pleaded with Beria for additional backing.
