The Journal was established in 1903 as the Proceedings of the Annual Meetings of the South African Association for the Advancement of Science. The annual volume became a monthly publication in August 1947. Since 1973, the Journal has in turn had a close association with Macmillan Journals in London (the then publisher of Nature), the Associated Scientific and Technical Societies of South Africa (AS&TS), the Foundation for Education, Science and Technology, and the National Research Foundation.
