Regular meteorological observations were made at Brown University by Alexis Caswell (1799-1877) who was Professor of mathematics, astronomy and natural philosophy. Caswell began recording these observations in 1831 and his “Meteorological Register; Providence, R.I.” was published in Smithsonian Contributions to Knowledge. Caswell kept these records until 1876; after that date the records were kept by the City Engineer.
Weather observations for Providence, RI continued at Ladd Observatory soon after the building was constructed in 1890. An instrument shelter was installed on the deck of the building next to the dome. These weather records were kept by Winslow Upton (1853-1914) who was Professor of astronomy and the first Director of the Observatory.
