Pictured here is the monument near the Observatory that was originally erected in 1912 in honor of the Observatory’s founder, Abbott Lawrence Rotch.  It was later etched with a summary of the climate information that was recorded during the Observatory’s first century (1885-1984).  This page lists the climate records on the monument that have been replaced since that time.
