Although trained in Spain, Rusiñol made sure to spend a few years in Paris for seasoning. Other Catalonian painters including Ramon Casas, Hermenegildo Anglada Camarasa and Ignacio Zuloaga did the same in those days.
Here are examples of Rusiñol's work.
An autumn scene.
He did a few courtyard paintings as well.
Kitchen of the famous Montmartre night-spot.
He had another painting of the same setting titled "Before the Morphine.".
Utrillo was probably the father of cityscape modernist Maurice Utrillo, whose mother most certainly was model and painter Suzanne Valadon.
That's Erik Satie the modernist composer.
And here he is with Suzanne Valadon, with whom he had perhaps his only serious affair. For some reason Rusiñol has Suzanne at the piano (so far as I know, she didn't play piano) and piano-playing Satie as the observer.
