Conversations: Isabelle Rousseau on twenty-two years of practice

Madame Rousseau receives her visitors in a small office above the salon de pratique on rue de Sèvres. The room contains: a desk; two upholstered chairs; a tall window that opens onto a courtyard with three plane trees; a single shelf of bound treatises whose oldest spine reads 1962; and a kettle. There is no smartphone. There is no clock that is visible from where the visitor sits. Madame Rousseau does not appear to need either.

This is an edited transcript of a conversation conducted in February of this year. Madame Rousseau requested that the recorder be left running for the full session and that the editors be the ones to make the cuts.

The Editors: You apprenticed under Madame Bertin from 2002 to 2006. What was the first thing she taught you?

Isabelle Rousseau: That the question of what to do is almost always less interesting than the question of what not to do. She made me sit and watch her work, for two months, before she let me touch a face. I thought I was being slow-rolled. I was being shown a discipline.

TE: Did you think of leaving?

IR: Once. There was a particular afternoon. I went home and made a list of the reasons I had come, and a list of the reasons I was thinking of going. The first list was longer. It is sometimes useful to take instructions from your own younger handwriting.

TE: You teach the Foundation residency at the Maison. What is the difference, if any, between what you teach the cohort and what Madame Bertin taught you?

IR: The protocols are the same. The texts are the same — the Maison has reprinted them, gently. What is different is the cohort. They arrive having read more than my cohort did at their age, and having seen more than my cohort had seen. They also arrive having been told, by an industry, that the work is faster than it is. The first week of residency is dedicated to gently disagreeing with that telling.

TE: You don't own a smartphone. Is that a position?

IR: It is a habit. It became a position by attrition. I make calls from a telephone in my apartment. People who need to find me find me. The work I do requires a kind of attention that a smartphone is engineered to interrupt. So.

TE: Final question. What is two grams of pressure?

IR: (Laughs.) It is what every student wants me to define and what no student can be told. It is what the discipline asks. It is what the discipline pays you back for. Three decades on, I have not stopped being surprised by how much it gives, and how little of it is required.
