Cincinnati Astronomical Society

The Cincinnati Astronomical Society (C.A.S.) was founded in 1911 by Dr. Delisle Stewart, formerly an astronomer at the Cincinnati Observatory in Mt. Lookout. Unsatisfied with the research being done there, Stewart envisioned a state-of-the-art astronomical observatory featuring a 27" diameter telescope, the largest in Ohio. Citizens responded to Stewart's concept by buying bonds to fund the new observatory. By the late 1930s construction began on the facility just north of this site. The Great Depression took its toll, however, and the observatory was never completed. The C.A.S. successfully transformed into an amateur society and continues to offer public astronomy programs and educational activities for schools, scouts, families, and C.A.S. members.
