Born in Lausanne, Switzerland, he worked mainly in France, from 1885 to 1925.
He was a painter, but his best works are perhaps wood-engravings.
I find that are masterly, among these, the series "Intimacies":
wood cut slices of life,
mostly of couple life.
Images are dominated by thick black spaces (the artist has to scoop out the white
areas in xylography).
But this black background makes even clearer the "pictures" that
Vallotton takes in the rooms of private lives, where he pitilessly catches
psychological moments and intercourses between charachters.
