Abstract: This article is devoted to the organization of the educational process in post-war Leningrad. This process is described as one of the factors of the rapid and sustainable recovery of urban industry in the second half of the 1940s. The blockade lasted for a long four years. The result of it was a massive destruction of the city. However, the main damage that Leningrad suffered and which significantly slowed down the process of its restoration was the mass death of people. The city is faced with an acute shortage of workers, primarily high-class professionals. The blockade caused huge damage to the material part of Leningrad universities. The elimination of this damage, carried out largely by the work of their employees, students and teachers, is one of the Great Pages of history. It was the combination of pedagogical and scientific thought that allowed many post-war profiles of industrial enterprises to appear. Students and young scientists actively contributed to the resumption of production of almost the entire range of pre-war products, as well as the development of new types of products, modern machines, machine tools, devices. As a result of the set of measures analyzed in this article, the Leningrad industry in terms of gross output reached the pre-war level in the late 1940s, and was able to exceed it by 1950.

Abstract: The article is devoted to the analysis of scientific, practical and production activities of employees of the Leningrad Polytechnic Institute named after M.I. Kalinin during blockade.

Most of the scientific works of the university scientists were of a practical nature. Being in extreme conditions, despite all the difficulties, teaching staff of the university continued to work, publish works, conduct experiments that made it possible to ensure the work of enterprises of the Leningrad industry, thereby making a huge contribution to the Victory over fascism.
