Hermine Poitou is a French designer and artist, and the wife of the English actor David Thewlis. They married on 6 August 2016.

That sentence is very nearly the entire public record about her, and this page is not going to pretend otherwise. There is no documented biography, no catalogued body of work, no interview archive and no verified net worth. She has never sought a public profile, and the pages that fill those gaps with confident detail are inventing it.

What is richly documented is her husband’s career — a Cannes best actor award, two BAFTA nominations, roles from Naked to Harry Potter to Fargo, and two published novels. That is below too, because it is the part of this story anyone can actually check.

Everything above is drawn from David Thewlis’s published biography, which is the only reliable source that mentions her. Read 20 October 2026.

Look at how short that table is. Nine rows, of which four say that something is not recorded. That is not a failure of research — it is the finding. A person can be married to a well-known actor for a decade and still, quite deliberately, leave almost no public trace.

What Is Not Known, and Why We Leave It Out

Other pages about Hermine Poitou carry a birth date, an age, an education history, a description of her design career and a net worth. We carry none of those, and it is worth explaining why rather than just leaving gaps.

Commonly publishedThe problem with it
A specific age or birth yearNo source records one. The figures online disagree with each other
Details of her childhood and educationNothing is documented. The descriptions are written to fill a heading
An account of her design careerNo studio, gallery, exhibition or client has been publicly catalogued under her name
A net worth figure, often around $800,000No filing, no disclosed earnings, no stated method. Attaching the words “unofficial estimate” does not make it a source
Claims about her familyShe is a private individual. Her relatives are not public figures and are not named here

A profile should be as long as the evidence allows and no longer.

The same rule is applied across every spouse profile on this site, including Kim Hasse and Tia Kemp. Where there is a document, we quote it. Where there is not, we say so.

The Marriage, and the Date Nobody Quotes

Here is the one piece of genuinely specific information this page can add.

David Thewlis and Hermine Poitou married on 6 August 2016. Most pages about her give only the year, and several give no date at all. They live in Sunningdale in Berkshire.

David Thewlis’s relationshipsYears

It is worth noting the contrast. His previous long relationship, with Anna Friel, was heavily covered by the British press for a decade. The marriage since 2016 has been almost entirely absent from it. That looks less like a lack of interest and more like two people making a different choice about publicity.

David Thewlis: The Documented Career

This is the verifiable half of the story, and it is a substantial one. He was born David Wheeler on 20 March 1963 in Blackpool, and took his mother’s maiden name professionally because his own was already registered with the actors’ union.

The Part Most People Miss: He Is a Novelist

Buried under the film credits is something that gets almost no attention. David Thewlis has published two novels with major houses.

  • The Late Hector Kipling (2007, Simon & Schuster) — a black comedy set in the art world.
  • Shooting Martha (2021, Weidenfeld & Nicolson).

It is a genuine second career rather than a celebrity side project, and it is the detail most profiles of him — and every profile of his wife — leave out entirely. Given that his wife works in art and design, a household containing a novelist and a designer is a more interesting fact than any invented net worth.

Why No Net Worth Figure Appears Here

A figure of around $800,000 circulates for Hermine Poitou. We are not repeating it, because there is nothing underneath it.

She has no public company filing. No earnings have been disclosed. No body of work has been catalogued and priced. And her husband’s earnings, which are also private, are not hers. A married couple do not share a net worth figure, and estimating one person from the other’s career is not a method.

Where numbers genuinely exist, we publish them — see our breakdown of UK presenter salaries or our ranking of the richest UK celebrities, both built on disclosed figures. Here there are none, and the honest page says so. For another profile of a partner who has stayed out of public life, see Kristina Dourif.

Conclusion

Hermine Poitou is a French designer and artist who married David Thewlis on 6 August 2016 and lives with him in Sunningdale. After nearly a decade of marriage to a well-known actor, that is still the whole of the public record, and it is clearly how she wants it.

This page is deliberately short on her and detailed on him, because that is the shape of the evidence. If something verifiable is published — an exhibition, an interview, a piece of documented work — we will add it. Until then, a profile that respects her privacy is also the only accurate one.
