History of the Cape Astronomical Association.
The Cape Astronomical Association (C.A.A.) is the oldest Astronomical Society in Southern Africa. The founding meeting was held on the 8th November 1912. This society existed for approximately ten years. The Johannesburg Astronomical Association was founded in 1918. On 23rd August 1922 the two societies amalgamated to form the Astronomical Society of South Africa (A.S.S.A.). The two parent associations respectively became the Cape Centre and the Johannesburg Centre of A.S.S.A.
