1) Planetarium at Jones Observatory in Chattanooga, Tennessee - It consists of a home built projector in 1951 under a 12' dome of corrugated card board and wood frame. The projector is a copper dodecahedron. The projector is still in use under a plaster 24' dome built in 1958.
Armand Sptiz on his visit there said he was going to sue for patent infringement. He took some of the improvements such as use of copper and the horizon light cutoff from this projector to use in his projectors.
The Jones Observatory was constructed for the Chattanooga school system in 1936. It is considered the first large public observatory and telescope in the south. It was leased for one dollar for 99 years to the University of Chattanooga during the second World War by the City of Chattanooga.

2) Argus Planetarium, Ann Arbor, Michigan -
a) Name: Argus Planetarium
b) Donor: Argus Camera Company of Ann Arbor, Michigan for a cost of about $6,000.
c) Location: Inside of Pioneer High School (was called Ann Arbor High School back then)
d) Dedicated: 1956
I have the proceedings for a meeting at Cranbrook Institute of Science of a group that was to become the Great Lakes Planetarium Association, which mentions that the Argus Planetarium was the only school planetarium at the time.
* Spitz A-1 serial #104 (installed by Armand Spitz) operated 1956 to 2002 September; run from a central console, with two slide projectors and a monaural sound system. This projector became unusable due to multiple mechanical failures and lack of suitable star lamps.
* Digistar 3SP operated 2003 February to Present; the entire theater was renovated. The cloth dome was replaced with a metal one and the seats were replaced with movable seats in a unidirectional configuration.
f) Dome: 24 foot cloth dome with internal metal ribs (these ribs were NOT pocketed, as were the later cloth domes)
g) Seating: 63 auditorium style seats in 2 concentric circles
h) Planetarium Directors:
* Dr. John Rosemergy (1956 to 1986)
* Stephen A. Schaffer (1986 to Present)

4) United States Air Force Academy Planetarium, Colorado Springs, Colorado -
Certainly, the most prominent of the planetaria located in schools, and it was probably one of the first to be permanently located in an institution of post-secondary education. It operated free-of-charge to nearly four million members of the general public from 1959 March until 2004 July 30. Originally using a Spitz Model B, this planetarium chamber now houses a Digistar II Projector.
