Interesting portraits of personalities in the memories of contemporaries . The book "We are mathematicians from the Lenin Mountains" is similar to the collective memoirs, in which fellow students enrolled in 1954 in the mathematical department of the Faculty of Mechanics and Mathematics of the Moscow State University named after M. In. Lomonosov, write not only about themselves, but also about their friends, teachers, about the events that they observed or were participants in them . And they write about how they were able to enter the unknown and know it. Graduates of the Faculty of Mechanics and Mathematics in 1959 are an intellectual part of our society, who actively participated in the development of the Moscow University and the whole of our country, from the beginning of the 60s of the twentieth century to the first years of the twenty-first century.
