Hayman Professor of Mechanical Engineering and Professor of Jet Propulsion, Emeritus, and his wife, Oral Lee Marble, concerning Tsien Hsue-shen [Qian Xuesen]. Tsien earned his PhD in aeronautics at Caltech in 1939 and in 1950 was the Robert H. Goddard Professor of Jet Propulsion.

Subsequent trip back to China by the Marbles in 1991-1992 finds Tsien’s health failing. Founding of library in Tsien’s honor; Marble succeeds in returning Tsien’s papers—which he has kept personally—to China. The interview includes personal reminiscences on the Tsien family, including Jiang Ying, Tsien’s wife, a musician and opera singer, and Tsien Yucon, his son, who earned a master’s degree at Caltech.
