Musee Zadkine, housed in his former home, just a hop, skip and jump from the Luxembourg Gardens in the 6eme.
It is small and perfectly formed, and a lovely way to pass an hour looking at beautifully serene and gentle sculptures.
You can easily see the influence of his friend Modigiliani and later Cubism. It was hard not to reach out and touch the sinuous forms.
Seek out the tranquil green courtyard and enjoy everything for free. There were only two other people there when I visited. Thank you Paris.
