Escofier-Cordier was a French statistician graduated from the University of Rennes, specialised in data analysis. She worked with Jean-Paul Benzécri on factorial correspondence analysis, for which she wrote the first computer program in FORTRAN in 1965 on IBM 1620 at the University of Rennes. She discovered the transition relations connecting the points-lines to the points-columns thus avoiding a double diagonalization but especially allowing a simultaneous interpretation of the representations of the lines and the columns,.
Her first major contribution is her thesis entitled L’analyse factorielle des correspondences, defended in 1965. This first presentation by AFC was for several years the only text available on this method.
