      Sep. 21, 2023

      RALPH ROSENBORG Ocean Waves.

      Est: $1,500 - $2,500

      RALPH ROSENBORG Ocean Waves. Watercolor and pen and ink on cream wove paper, 1936. 280x383 mm; 11x15 inches. Signed and dated in ink, lower right recto. Provenance: Conner Rosenkranz, New York, with the label. Rosenborg (1913-1992) was born in New York to Swedish parents and proved to be a precocious young artist early on. As a teenager, Rosenborg won a scholarship to attend art classes at the American Museum of Natural History. This learned keen observance of nature would be sustained throughout his artistic career. Rosenborg began studying with the artist Henriette Reiss, who was associated with Wasily Kandinsky, and introduced Rosenborg to avant-garde ideas. Early in his career, Rosenborg exhibited in group shows in New York, where his focus on nature, rather than geometric forms set him apart from his contemporaries. He had his first solo exhibition at the Eighth Street Theater in 1935. He became known for his use of bright colors, attention to visual movement and rhythm, and in his oils, textures. During the 1940's, Rosenborg was in a romantic relationship with artist Louise Nevelson, but due to his temper and alcoholism, had few other long term friends or a longstanding relationship with a particular gallery. Though he continued to associate with and show with the New York Abstract Expressionists during the 1950's, Rosenborg's style remained largely independent from those influences. He had a long career, showing his work at various galleries through the 1980's. In a review of his show at the Princeton Gallery of Fine Art in 1983, writer Vivien Raynor posited that "Rosenborg seems powered less by a love of nature than by a passion to dominate it with his own immutable laws."

BIOGRAPHY: Although Ralph Rosenborg has painted abstract throughout his life, nature has served as his perennial motif. He won a scholarship while still in high school to Saturday art classes at the American Museum of Natural History in New York City. After classes ended, he continued to study privately with his teacher there, Henriette Reiss, who provided not only exacting technical training, but broad-based instruction in music, literature, and art history. More significantly, Reiss had worked with Kandinsky earlier in her career and introduced her young protege to the vast arena of vanguard European ideas. After four years, Rosenborg was ready to exhibit. He showed frequently during the 1930s- initially in group exhibitions at ACA Galleries and later in Mayor La Guardia's 1934 "Mile of Art" at Radio City. His first solo exhibition, at the Eighth Street Theater in 1935, was followed by shows at various galleries almost annually throughout the 1940s. A highly personal artist, inclined toward interpreting nature rather than the geometric form pursued by many of his fellow members of the American Abstract Artists, Rosenborg wrote in 1955: "Painting will always remain a super-real world to me, devoid of all modern forms of blasphemy. It is a world in which the immensity of creation moves me to a personal form of prayer and contemplation. It is also a world in which its laws demand a personal integrity of purpose, a simple humbleness, and a sufficient set of experiences as the basic requirement for admission to it. During the 1930s and 1940s, Rosenborg moved freely between expressionist watercolors evocative of the rhythms and colors of nature (such as the Untitled watercolor of about 1938) and more consciously structured oils, such as The Far-away City in which deep-toned, dream world landscapes take on the color and architecture of expressive stained glass. He paid little heed to modernist theories of surface and structure that fascinated many of his contemporaries. Later during the 1950s, Rosenborg's paintings increasingly reflected the energies, as well as the appearances, of the natural world. Tumultuous seascapes, serene landscapes, and brightly colored floral still lifes, were all executed with an attention to richly textured, heavily painted surfaces. Although New York City has remained home for Rosenborg throughout his career, he has traveled widely. In 1966, an award from the National Council on the Arts and Humanities enabled him to tour Europe. He continually strives upward in his work, and frequently draws an arrow in a rectangular box on the back of his paintings. Originally a Mayan motif, the arrow, for Rosenborg, "signifies that I will strive to always go up, aesthetically, spiritually, and from all practical points of view. It's very important because I try to stay on earth, but actually, the painting is another world."
