Harlan J. Smith (1924-1991) served as director of McDonald Observatory from 1963 to 1989. He was the first University of Texas director, after a partnership with the University of Chicago's Yerkes Observatory ended. Among many other accomplishments, he initiated the construction of the 2.7-meter (107-inch) telescope at McDonald that now bears his name. (Credit: McDonald Observatory)
