The post-revolution and postwar periods gave a new life to the city. The power machinery engineering, metallurgical production, instrument-making and other industry branches began to develop. The development of science was closely connected with the inauguration of the Taganrog State University of Radio Engineering. In the seventies and eighties, Taganrog was known as an important scientific and industrial center of Southern Russia. Taganrog companies produced: steam-boilers, self-propelled combine harvesters, drill-, casing-, oil-, gas-, and water-pipes, gears for searching fish and other installations. Taganrog products were exported to over 50 countries of the world.
