From a video, a documentary called Who Gets to Call It Art? by Peter Rosen. (review) This is the Henry who was …. well what? Some sort of mentor to Andy Warhol and David Hockney and a whole bunch of N.Y. abstract expressionists. Will write more here, and post work from both of those artists of Henry if I can find it, and hopefully one by Alice Neel. It is such a male bunch, but there were women and she must have been one, as well as Lee Krasner, they still fall away in the gender gap.
Have found some more:
His name is Henry Geldzahler, but was known just as Henry.

Hard to find the paintings I want online.
