Jean-Paul Benzécri

Leaving for the United States in 1955 for Princeton University, after a 4 months study he submitted a Ph.D. thesis in differential geometry entitled Variété localement plates[1] under the supervision of Henri Cartan.

From 1959 until 1960 he did conscripted military service in the Operational Research Group of the French Navy where he practiced multidimensional data modeling by traditional analytical methods without the use of a computer.

Since his early work in 1963 on Natural Language Processing (NLP), Benzécri got the intuition that electronic computing was going to be the Novius Organum (i.e., the new tool) enabling to solve the problem cooperatively between mathematics, logic and linguistics.

Inspired by the pionneering works of Louis Guttman and Chikio Hayashi as well as by the distributional methodology of Zellig Harris, he devised a geometric equivalence to these approaches by searching the principal axes of inertia of a weighted cloud of points.

But he was also opened to reintroduce a new statistical framework into this purely exploratory process by deriving an a posteriori projection of supplementary variables (i.e. columns) and individuals (i.e. rows).
