For eighty years, Elmira College possessed an observatory built by Professor Charles Farrar. Professor Farrar began buying telescopes for the observatory in 1859, and construction began in August 1859. The observatory first opened for use in April 1860 under the control of the Elmira Academy of Sciences. Twenty years later, control was transferred to Elmira College. Students would gather in the observatory for "dome parties". "The domed building, which occupied a triangular plot fronting on Seventh Street, stood until 1939".
