 Lizard Hollow Observatory became operational in September 2000.   The 28-cm W.R. Beardsley telescope
 of the Observatory was dedicated on October 4,  2000.   The late Wallace R. Beardsley was an astronomer
 at the Allegheny Observatory of the University of Pittsburgh whose interests were in binary star orbits and
 stellar spectroscopy.
