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.
