She published as a mathematician at least in the period 1943–1979.


Among other things, she published Histoire comparée des numérations écrites (Flammarion 1975), where they are on p. 51-52 and in the chapter "Les grands nombres en numération parlée", p. 566-574, (in German: The large numbers literally ) made use of the terms échelle longue and échelle courte for the first time .

In the 1960s she also published on mathematics in Babylonian cuneiform texts.
