Named in memory of Ching-Sung Yu (1897–1978), a Chinese-American astrophysicist, whose spectrophotometric measurements of 91 stars at the Lick Observatory in the early 1920s represented a milestone in research on stellar energy distribution. After returning to China he established the Purple Mountain Observatory and served as its first director. He also developed the site of what is now the Yunnan Observatory, was director of the Academia Sinica’s Institute of Astronomy and president of the Chinese Astronomical Society. After World War II Yu worked at the Harvard College Observatory and later became professor of astronomy and director of the Williams Observatory at Hood College in Frederick, Maryland.
