Henry Dukso Moon was born on September 28, 1914, in San Francisco, California. His
father, Yang Mock Moon, a scholar and activist for Korean independence, had emigrated to
the United States from Korea in 1903; his mother, Chan Sung Lee, had come to the United
States from Korea as a "picture bride" in 1913. Henry Moon graduated from Galileo High
School in San Francisco in 1931, and went to the University of California, Berkeley,
where he received his A.B. degree in Medical Sciences in 1935, upon his completion of the
first year of the curriculum of the University of California School of Medicine. From
1935-1937 he was a graduate student in Anatomy (M.S., 1937). While at Berkeley's
Department of Anatomy and the Institute of Experimental Biology, he came under the
influence of Professors William R. Lyons and Herbert M. Evans, and in Professor Lyons'
laboratory he did much important work in studying ACTH that had been isolated and
purified there from prolactin derived from sheep pituitary glands. His brother, Dr.
William H. Moon, has noted that "Henry [Moon] was the first second-generation Korean to
be born in San Francisco, and the first San Francisco-born Korean to graduate from U. C.
Berkeley and U.C. Medical School in San Francisco."
