F.A. Zander and Yu.V. Kondratyuk,pioneers of rocket engineering

The paper briefly describes the life and activities of F.A. Zander and Yu.V. Kondratyuk (A.I. Shargei), pioneers of domestic rocket engineering who made a significant contribution to the development of cosmonautics and rocket technologies. The main ideas and proposals of these prominent scientists and inventors in the field of rocket and space engineering, which found their application in space conquering, are considered. To the 120th anniversary of F.A. Zander and 110th anniversary of Yu.V. Kondratyuk
