The true history of physics can only be read in the life stories of
those who made its progress possible. Matvei Bronstein was one of those
for whom the vast territory of theoretical physics was as familiar as
his own home: he worked in cosmology, nuclear physics, gravitation,
semiconductors, atmospheric physics, quantum electrodynamics, astro-
physics and the relativistic quantum theory. Everyone who knew him was
struck by his wide knowledge, far beyond the limits of his trade. This
partly explains why his life was closely intertwined with the social,
historical and scientific context of his time. One might doubt that
during his short life Bronstein could have made truly weighty
contributions to science and have become, in a sense, a symbol of his
time. Unlike mathematicians and poets, physicists reach the peak of
their careers after the age of thirty. His thirty years of life,
however, proved enough to secure him a place in the Greater Soviet
Encyclopedia. In 1967, in describing the first generation of physicists
educated after the 1917 revolution, Igor Tamm referred to Bronstein as
"an exceptionally brilliant and promising" theoretician [268].
