The first edition of the first Soviet book to systematically document the young International Mathematical Olympiad, written by Elena Morozova and Ivan Petrakov, both of whom had personally led Soviet delegations to the fourth through seventh Olympiads. The book collects every problem set from the first seven Olympiads (Romania, 1959, through East Germany, 1965) together with jury materials and selected national-olympiad problems from the participating socialist countries, and opens with a history of the competition: founded in the summer of 1959 at the initiative of the Romanian Ministry of Education and the Romanian Academy of Sciences with seven participating countries, the Olympiad quickly became an annual summer tradition rotating among the socialist states, each national team fielding eight finishing secondary-school students who were typically winners of their own national olympiads. The preface traces the deeper Soviet tradition behind this internationalism: the first Soviet school olympiads were held in Leningrad in 1934 and Moscow in 1935 at the initiative of leading Soviet mathematicians, spreading nationally after the war and inspiring parallel olympiads in physics, chemistry, astronomy, geography, and biology, and, by 1965, even in linguistics at Moscow State University. Written from the inside by the very officials who led Soviet delegations to these early competitions, the book stands as a primary historical source for the formative decade of what remains today the most prestigious international competition in school mathematics, as well as the direct ancestor of a long-running Soviet and Russian olympiad-book series that continued expanding under Morozova, Petrakov, and later Skvortsov through subsequent editions covering many more Olympiad years.
