Statement of Significance (as of designation - December 20, 1989):
Founded in 1885 by Abbott Lawrence Rotch (1861-1912), this observatory the principal structure associated with the history of weather observation in the United States. The Blue Hill took a leading role in the newly emerging science of meteorology and was the scene of many of the first scientific measurements of upper atmosphere weather conditions; by 1895, the observatory was the source of weather forecasts of remarkable accuracy. Knowledge of wind velocities, air temperature, and relative humidity at various levels came into use as vital elements in weather prediction due to techniques developed at this site.
