Wallace R. Beardsley (1922 - 1991)

Wallace R. Beardsley (June 4, 1922-March 16, 1991) attended the University of Washington, where T. S. Jacobsen apparently first taught him astronomy, though his bachelor's degrees were in mathematics and physics (1948). In 1950 he began his studies at the Yerkes Observatory. Departure of his thesis adviser in 1953 evidently led to his taking a position at the Allegheny Observatory that year, and to a delay in receiving the Yerkes S.M. degree (1960). His research interests centered on astrometric and spectroscopic observations of a variety of binary stars.
