The dealer who bankrolled Cubism

Walk into 28 rue Vignon, a side street near the Madeleine church in Paris, in 1907, and you would find a room about four meters square — roughly a single bedroom — with almost nothing on the walls. The man behind the counter was Daniel-Henry Kahnweiler: 23 years old, German, born in Mannheim into a banking family that had shipped him off to Paris and London to learn the money trade. He had learned it well enough to know what he wanted to do instead. With a small loan of family money he had rented this closet of a shop, and he intended to sell the most unsellable pictures in Europe.

Within a couple of years he had quietly signed up the wildest young painters in Paris: Pablo Picasso; Georges Braque; and two of the Fauves — the “wild beasts,” a movement of painters who slapped down raw, unmixed color — namely André Derain and Maurice de Vlaminck. Soon a young Spaniard named Juan Gris joined them. Kahnweiler bought their canvases when nobody else would, back when the only people who admired this work were the handful of people making it. On the side he also dealt in African and Oceanic carvings — the same kind of objects that had just rewired Picasso’s eye.

Here is the part that sounds backwards. Kahnweiler did the opposite of what a dealer is supposed to do: he kept his painters out of sight. The normal way to launch a new artist was the Salons — the giant annual public exhibitions in Paris where critics, buyers and the press discovered who was next. Kahnweiler banned his painters from showing there. Instead he sold privately, one canvas at a time, to a tiny circle of true believers — collectors in Germany, Russia and the United States who would buy on his word alone.

It worked because scarcity is its own advertisement. If the only place to see a Picasso was in a German industrialist’s drawing room, owning one meant you were in on a secret the world hadn’t caught up to yet. To free the painters to take risks, Kahnweiler eventually put them on what amounted to a fixed monthly payment in exchange for first claim on everything they made — though the formal exclusive contracts came later, around 1912; in these early years it was a looser, trusting arrangement.

The work he was hiding had, by then, picked up a name — and not from the painters. In 1908 Kahnweiler hung some Braque landscapes in this shop. A critic named Louis Vauxcelles walked in, sneered that Braque had reduced everything to “petits cubes” — little cubes — and the insult stuck. That sneer is why we now say Cubism: the art of breaking the world into hard, angular blocks. So when Picasso painted Kahnweiler’s portrait two years later, he was not just painting a friend. He was painting the system that paid for Cubism, in the style that system had bankrolled into being.
