Although I had read Joseph Cornell's biography a couple of times, I hadn't realized that it was the amazing dot woman artist Yayoi Kusama who had been his first girlfriend (when he was 60). I blogged about Cornell a couple of times: here and here.
I also recently blogged about Kusama ( LINK).
She talks about the affair (lasting 10 years) in an old interview with Kusama by Grady Turner in Bomb Magazine (1999).
