That's what the new film "Leonie" is about. Leonie Gilmour wasn't a great artist. She took up with a writer and edited him into near-greatness. He then scurried back to Japan and married somebody else.
But the child from that union became sculptor and landscape architect Isamo Noguchi, one of the major figures in 20th century art.
"Leonie," starring Emily Mortimer as Noguchi's mom, must qualify as the oddest "woman ahead of her time" bio-drama in living memory. Here was an early 20th century alumnus of Bryn Mawr and the Sorbonne who never had much of a career herself, but whose influence came from a child she had outside of a conventional marriage and outside the racial boundaries of her day.
In 1901, she responds to an "editor needed" ad.
