Erling Andersen, Professor in the Economics Institute, University of Copenhagen, and student of Georg Rasch, died on 18 September 2004, at 64 years old. Here is part of his personal recollection of Henri Caussinus:
"When writing my book on categorical data, published in 1980, I included a chapter on two-way contingency tables with dependencies. From my teacher and predecessor Georg Rasch I have learned about the model, later to be called RC-association models by Leo Goodman, but I still looked around to see if somebody had not addressed this problem. In my search I became aware of the paper by Henri Caussinus in the Annales de la Faculté des Sciences de l'Université de Toulouse . I shall not claim that I understood all 111 pages in French. But I immediately saw the importance of Henri's work, and (as anybody can check,) he is duly quoted in my 1980 book.
"It was some years later that I actually met Henri. Actually at a COMPSTAT meeting in Copenhagen. I did not know what to expect. But it so happened, that I had just started playing the French Horn, and persuaded my teacher, solo player in the Royal Danish Orchestra, to give a concert in one of the churches in Copenhagen, together with several of his colleagues in the Royal Orchestra. I remember that my wife Ellen and Henri and me sat in one of the front boxes of the church. Henri really enjoyed the music, and he was much pleased, when we after the concert got a little chat with the royal musicians.
"Some years later I discovered - maybe a bit later than several of my Dutch friends and colleagues - the importance of correspondence analysis and its relationship to the RC-association model as formulated by Georg Rasch and Leo Goodman. I decided, therefore, to spend a couple of months with professor Escoufier in Montpellier, especially to unravel the mystery of MCA = Multiple Correspondence Analysis. During my stay in Montpellier, I was invited to come to Toulouse for two days. It became two of those days that will always stay in my mind as a combination of many long talks of what had happened to the theory of contingency tables for the last 20 or so years, and of other long talks of what has happened to our children and what we enjoyed and expected of our grandchildren."
