Zhao Jiuzhang (1907–1968) was one of the 23 recipients of the Two Bombs and One Satellite Merit Medal. Devoting his whole life to serving the nation through science and technology, and guided by an exceptionally far−sighted strategic vision, he established and advanced China's basic research in geophysics, space physics, atmospheric science, ocean wave research, and seismology, and was one of the initiators and founders of China's artificial satellite program. Taking into full account the actual conditions of New China, Zhao Jiuzhang emphasized that "missions drive the development of disciplines, while disciplines in turn support the fulfillment of missions". Learning from his scientist spirit and carrying forward his devotion to China, his visionary foresight, his pioneering and innovative drive, and his distinctive philosophy of education are of far−reaching practical significance for further strengthening basic research and accelerating China's endeavor to build herself into a leading country in science and technology in the new era.
