I finally had to give in and google on the info and hints you gave and found: Chaim Soutine
This is actually not a name I know, so would never have guessed it. But I can see that the lack is my ignorance and not his obscurity. I may well have seen one of his works without the name registering, perhaps in a special exhibition.
I'm not taken with dead things, but some of the landscapes look very interesting. Must have a look next time I'm at the Tate. Thank you for the introduction!
