Millionaire philanthropist and partly closeted freethinker William Smith erected this small but well-equipped observatory—along with a comfortable brick house for its director—next door to his own red-brick mansion in Geneva, New York, in 1888. Smith recruited astronomer William Robert Brooks (1844-1921), who used the observatory’s 10-inch Warner and Swasey refractor telescope and 4-inch transit telescope to discover a great number of comets, bringing scientific fame to Geneva just as Smith had hoped.
Owned by Hobart and William Smith Colleges until 1974, the structure was privately acquired in 1974 and has since been restored.
