Agnes Martin (1912–2004) was an American painter.
She liked to say that the work needs to be inspired and that you can't force it there by technical or intellectual means. That really resonated with me and I think it's very visible in her work and how effective her work is.

A Guggenheim exhibition she was in with Frank Stella, Systemic Painting, really celebrated work organized around rigid rules and simple repetition that resisted formal interpretation.
