When I was invited by our President, Blair O. Rogers, to write the early history of the ISAPS and to also present a summary at the XII Congress in Paris(1), I accepted with pleasure as I had already corrected an initial report written by Mario Gonzalez-Ulloa (2,3), I also presented a report about at the 1985 Congress in Madrid(4), and, as Co-Chairman and Chairman of the Education Council, I proposed to the Executive Committee to write the 20 (or 25) year history of the ISAPS(5,6). I thought that I was entitled to do so, since I had participated at the first meeting in Sao Paulo (Fig.1), in October 1-4, 1969, in the foundation of the Society and thereafter, up to 1992, in almost all the meetings of the Executive Committee.

On the other hand my files are presumably the most complete, including minutes, reports, bulletins and hundreds of letters, to which those of the IPRS, concerning the ISAPS, have to been added, which are also in my hands as present General Secretary of the Confederation.
