This 1977 biography is a definitive Soviet scholarly account of the life and legacy of Niels Bohr, published as part of the prestigious "Scientific-Biographical Series" by the USSR Academy of Sciences. Bohr’s unique relationship with Soviet scientists—most notably his friendship with Lev Landau and his visits to the USSR—gave him a near-legendary status in the Soviet scientific community, making this meticulous study particularly significant.
The volume is divided into two distinct analytical sections. The first, by E. M. Klyaus, traces Bohr’s personal history, from the founding of the Copenhagen Institute to his emergence as a global advocate for "Open World" scientific cooperation and nuclear peace. The second part, authored by U. I. Frankfurt and A. M. Frenk, provides a rigorous reconstruction of Bohr’s intellectual journey. It delves into the evolution of the Bohr model of the atom, the formulation of the Correspondence Principle, and his philosophical debates with Albert Einstein over the nature of reality and the Complementarity Principle.
