EPR in the USSR: the thorny path from birth to biological and chemical applications

In 1944, electron paramagnetic resonance (EPR) was discovered by Evgenii Konstantinovich Zavoisky in the USSR (Union of the Soviet Socialist Republics). Since then, magnetic resonance methods have contributed invaluably to our knowledge in many areas of Life Sciences and Chemistry, and particularly in the area of photosynthesis research. However, the road of the magnetic resonance methods, as well as its acceptance in Life Sciences and Chemistry, was not smooth and prompt in the (former) USSR. We discuss the role played by many including Jakov K. Syrkin, Nikolai N. Semenov, Vladislav V. Voevodsky, Lev A. Blumenfeld, Peter L. Kapitza, and Alexander I. Shalnikov during the early stages of biological and chemical EPR spectroscopy in the USSR.
