One of the tangential intrigues of art is the Bohemian lifestyle that often attends it — that liberated, marginal existence that feeds upon and nourishes creative intensity. The painter Janice Biala (1903–2000) lived such a life and lived it to the very fullest.

Her résumé sounds like a potboiler: Overcoming a precarious childhood, she pursued a seven-decade-long career that spanned the art worlds of both New York and Paris, and befriended many of the giants of art and literature on both sides of the Atlantic. Generous but tough — and always opinionated — she produced a unique body of work reflecting her peripatetic life in the limpid, graceful style of French modernist painting. Her geographical and stylistic distance from the New York School meant that she never achieved the fame of some of her contemporaries, but recent shows of her work at Tibor de Nagy Gallery — where her paintings are currently on view until January 5 — have brought her some long-overdue attention.

Biala was born Schenehaia Tworkovska in a region of eastern Poland historically subject to pogroms. By 1913, she left with her Jewish family for a tenement on New York City’s Lower East Side. (The young girl was later to take her hometown’s name as her own. Her older brother Yakov changed his name, too — to Jack Tworkov.) As a teenager, Biala worked various jobs in order to attend classes at the Art Students League and the National Academy of Design, where she studied with Charles Hawthorne. Edwin Dickinson and William Zorach became her friends and mentors. After a brief and unhappy marriage, Biala left for Paris in 1930, where her encounter with Ford Madox Ford was to change her life.

At age 26, she was less than half the author’s age, but their romantic relationship endured until his death in 1939. For both it marked a time of emotional nourishment and artistic productivity . Through Ford, Biala met such luminaries as Picasso, Matisse, Joyce, and Pound. She later wrote that in living for Ford, she had found herself: “He found a little handful of dust and turned it into a human being.” The comment tells not only of the poignant depth of her love, but also the forthrightness of her self-image. Perhaps, though, she undersold herself: When they met, Ford, an inveterate womanizer, was in a deeply depressive and lonely state. Under Biala’s attention, he regained his writing stride, while Biala managed his contracts and illustrated several of his books. After his death, she became his literary executor, staunchly defending his reputation against the insufficient praise of critics.

When Ford died in 1939, Biala barely had time to secure his papers before the Nazi onslaught. She departed for New York, where her brother Jack Tworkov, now well-connected in the New York art world, introduced her to de Kooning and other future Abstract Expressionists. In 1943, Biala married the French artist Daniel Brustlein, best known to New Yorker readers as the cartoonist Alain. Again, theirs was a mutually supportive relationship, as Biala collaborated with Alain in two-person exhibitions and on a number of children’s books. The couple shuttled between Paris and New York for many years before settling permanently in France.

Over the years they befriended Saul Steinberg, Henri Cartier-Bresson, Alberto Giacometti, and Joan Mitchell. Biala’s work, regularly exhibited in Paris and New York galleries since the 1930s, appeared in numerous museum shows. She continued to exhibit to the very end, with her final show at Kouros Gallery in 1999. She died the following year at age 97.

Biala lived as she wished — simply but thoroughly, and in the company of remarkable artists and writers. Spanning nearly 40 years, the paintings and mixed-media collages now on view at Tibor de Nagy Gallery reflect her unpretentious pleasure in her visual surroundings: the street scenes and monuments of France, Spain, Italy, and Morocco. Her admiration for Matisse shows in her simplified descriptions and planes of bright but subtly adjusted colors. In “Bateau sur la Seine” (1980), myriad grays and greens convincingly catch a river’s surface, alternately absorbing and reflecting light. Just two condensations of color punctuate its expanse: a patch of warm white, perfectly capturing a houseboat’s buoyant weight, and the rich, opaque green of a tree’s foliage rising from the near shore. “Open Window” (c. 1989) records a scene reminiscent of Matisse: a window view framed by vertical notes of curtain, wall, and the glass panes of the inward-turned sash. Biala’s hues beautifully convey the illumination of the interior and do so with a self-satisfaction quite alien to Matisse, whose unease disclosed itself in more compulsive contrasts and more swiftly cutting lines. All of Biala’s paintings seem touched by a tough ingenuousness — never sentimental or naïve, but slightly nostalgic in their playful intimacy. Suffusing them is the outlook of a painter who has found what she needs and knows what she wants to do. The results glow with a wondrous candor.
