Paulette Destouches-Février

The same year, Gaston Bachelard cited her work on the Heisenberg principle and the Schrödinger equation in his book The Philosophy of No: A Philosophy of the New Scientific Mind, published in 1940 by Presses Universitaires de France, explaining that "the works of Mrs. Février prove that this logic is a three-valued logic.".

She then taught in several high schools in the provinces and in Paris, while continuing research work with Jean-Louis Destouches, whom she married in 1941.

[3] On that occasion, journalist Jacqueline Piatier wrote on July 20, 1950, in Le Monde:[3]From her graduate diploma on a three-valued logic, the result of her reflections on the works of Mr. Louis de Broglie, a young student, Mrs. Février, entered the heart of the debate.

Since then, guided by love, Mrs. Destouches, a philosophy agrégée, has made presentations to the Academy of Moral and Political Sciences, written in the Journal de Physique, and obtained a doctorate in mathematics.She divorced Jean-Louis Destouches in 1950 but remained his intellectual companion until his death in 1980, and together they continued their collaborative work.

She left teaching in 1961 for a position as a CNRS engineer at the Blaise Pascal Institute, presented a second third-cycle doctoral thesis in statistical mathematics in 1967, devoted to the structure of experimental and predictive reasoning in physics,[4] and then ended her career as a cultural advisor to the French Embassy in Sweden and director of the French Institute in Stockholm.
