Construction
Ladd Observatory was designed by the Providence-based firm of Stone, Carpenter & Willson. The building was added to the National Register of Historic Places in 2000.
Telescope
The main telescope is a 12-inch (30 cm) refractor with a lens made by John Brashear following the design of Charles S. Hastings. The equatorial mount and mechanical clock drive were made by George N. Saegmuller.
Timekeeping
Besides astronomical research and education, Ladd sent out a time signal for decades. When they decided to stop the service in the 1970s, they discovered that nobody was actually receiving it.
Associations
Astronomers associated with Ladd include Winslow Upton, Frank W. Very, Frederick Slocum, Robert Horace Baker, and Charles H. Smiley.
H. P. Lovecraft had free access to the observatory for several years and wrote astronomy articles for Providence newspapers based upon his study there between 1906 and 1918.
