Contributed by John Goodrich / Hindsight, of course, is 20/20. Looking back at the early decades of modernism, we may sense something inevitable about the ascent of Picasso and Matisse. Weren’t both driven, gifted artists poised to take advantage of their cultural moment? And wasn’t the time ripe for Matisse’s upending of expectations of color, and Picasso’s overturning of pictorial structures? Of course, life is not so tidy and linear for the artists operating in the moment. As the luminous exhibition “Make Way for Berthe Weill: Art Dealer of the Parisian Avant-Garde” at NYU’s Grey Art Museum demonstrates, none of the early modernists had a monopoly on talent or a singularly dominant vision of what painting had to be.
