The Cincinnati Observatory, “The Birthplace of American  Astronomy,” is the oldest professional observatory in the United States.  Ormsby MacKnight Mitchel, the “Father of American Astronomy,” founded the  observatory in 1842.  John Quincy Adams laid the cornerstone  for the observatory on Mt. Ida, later renamed Mt. Adams. The  original Merz und Mahler 11-inch refractor telescope was put into service  in 1845 and is still in use here today on Mount Lookout.

Studies on the feasibility of building a hydro plant in the site were initiated in 1893. The increasing need for power that was cheaper and easily adapted to mine underground use drove the Lota coal mine company to develop a study of alternatives for this purpose. Engineer William E. Raby traveled to the United States and Europe to assess the use of electricity generation and transmission. The availability of the Chivilingo hydro resources arose as a better alternative to a steam plant.

The Cincinnati Observatory, founded by Ormsby MacKnight Mitchel in 1842, is America’s oldest public/professional observatory. The observatory was situated on Mt. Adams, east of the current downtown Cincinnati; the hill was named for former President John Quincy Adams when he laid the observatory’s cornerstone. In 1873 the observatory was relocated to Mt. Lookout when it became a component of the University of Cincinnati (UC). From 1870s until 1930s the stellar proper motion studies reigned as the observatory’s principal activity.
