Harlan James Smith
American astronomer (1924–1991)

Harlan James Smith (August 25, 1924 – October 17, 1991) was an American astronomer. He served as director of the University of Texas McDonald Observatory from 1963 to 1989, where, among other accomplishments, he initiated the construction of the Harlan J. Smith Telescope, a 2.7-meter (107-inch) reflector bearing his name .
Smith was born in Wheeling, West Virginia, the son of Paul and Anna McGregor Smith. While attending Wheeling High School he was named first runner up in the "Westinghouse National Science Talent Search". From 1943 until the end of World War II he served in the U.S. Army Air Corps, performing weather observation. Following the war he attended Harvard University, earning a B.A. in 1949. In 1950 he married Joan Greene, and by 1951 had earned his M.S. degree from Harvard. He began teaching at the astronomy department at Yale University in 1953, but still completed his Ph.D. from Harvard by 1955. During his career he studied variable stars, the radio emission from planets, as well as photometry and astronomical instruments. With Dorrit Hoffleit, he was the first to observe the optical variability of quasars, and discovered a class of variable stars known as Delta Scuti variables.

Why this record matters
The subject matters to the general reference register because the source frames it as american astronomer (1924–1991). Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 10, 2026. The linked authority identifier is Q2582109. VIAF identifies the subject as 14855246. The Library of Congress control number is n84134835. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1924, 1991, 1963 and 1989.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
