Jean-Jacques Henner and "la vie romantique"

If there's a festival in every village in France, there's a museum on every corner of Paris. One of them celebrates the art of Jean Jacque Henner, but it's closed for renovations, so in the interim the wonderfully named Musee de la Vie Romantique (fr) has stepped up and culled about a hundred of Henner's works for exhibition (Bloomberg). Which raises a question -- who the hecks is Jean-Jacques Henner?

Henner was a contemporary of the Monet/Manet crowd and "a confirmed bachelor," which is often a secret code for "gay."  But in Henner's case, his subject was something which would seem to belie that assumption. His specialty was "scantily clad girls with an aura of pious chastity," a description that makes me chuckle as I write it. His pictures were extremely popular during his life, but after his death he fell into obscurity, which may be the ultimate judgment of his paintings. I haven't yet found an informed critique of his work, so counter to my own ignorant conclusion: he does have his own museum, after all, which owns 1,000 of works, and which will presumably re-open with trumpets and celebrations in the not-too-distant future.
