Many museums are drawing audiences with art that is ostensibly more entertaining than stuff that just sits and invites contemplation. Interactivity, gizmos, eating, hanging out, things that make noise - all are now the norm, often edging out much else.

Imagine it's 1981. You're an artist, in love with art, smitten with art history. You're also a woman, with almost no mentors to look to art history just isn't that into you. Any woman approaching art history in the early eighties was attempting to enter an almost foreign country, a restricted and exclusionary domain that spoke a private language.

Willem de Kooning is generally credited for coming out of the painterly gates strong in the forties, revolutionizing art and abstraction and reaching incredible heights by the early fifties, and then tailing off.

I also take pleasure in the so-called negative power in Grotjahn's work. That is, I love his paintings for what they are not. Unlike much art of the past decade, Grotjahn isn't simply working from a prescribed checklist of academically acceptable, curator-approved 'isms' and twists.

It is not possible to overstate the influence of Paul Cezanne on twentieth-century art. He's the modern Giotto, someone who shattered one kind of picture-making and invented a new one that the world followed.
