This is one of the earliest US foundry-machine shops remaining in operation and one of the few water powered. It was founded by Samuel N. Knight (1838-1913) to manufacture machinery for the gold mines of the Mother Lode region. Knight was one of several inventors experimenting with impulse turbines to exploit the area's abundant high-head water power for driving hoists, ore stamps, and other mining machinery.

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.
