The special exhibition Helen Frankenthaler at the Kunstmuseum Basel presents more than fifty works spanning six decades of the American artist’s career. It offers a comprehensive overview of her oeuvre and is the largest exhibition of her work ever held in Europe, as well as her first institutional solo show in Switzerland.
Helen Frankenthaler (1928–2011) is recognized as a central figure in postwar American art and a key representative of Abstract Expressionism. She is best known for developing the soak-stain technique in the early 1950s, in which diluted paint is poured onto unprimed canvas laid on the floor. This innovation significantly influenced the emergence of Color Field painting.
The exhibition highlights Frankenthaler’s engagement with historical art from the fifteenth to the twentieth century, presenting her abstract paintings for the first time in dialogue with earlier works that inspired her. Her large-scale, luminous compositions are characterized by intense color, lyrical handling, and a balance between spontaneity and structural control. In addition to her celebrated paintings on canvas and paper, the show also includes her acclaimed prints and works in other media.
The exhibition was prompted in part by the museum’s 2024 acquisition of the major painting Riverhead (1963), a gift from the Helen Frankenthaler Foundation. Frankenthaler continued to refine her approach throughout her career while repeatedly returning to the soak-stain method that defined her pioneering contribution to modern painting.

Room 1: Artistic Influences
Frankenthaler becomes part of the New York art scene in the early 1950s, just as the city is emerging as a new center of the international art world and replacing Paris as the cultural epicentre. She belongs to the first generation of artists shaped by this newly ascendant modern art milieu. She begins a relationship with the art critic Clement Greenberg and quickly gains access to the art scene in New York. They entertain a lively dialogue about art.
Frankenthaler devotes herself to abstract painting and departs from traditional forms she had learned in college. Her early works are inspired primarily by Arshile Gorky (1904–1948), Wassily Kandinsky (1866–1944), Joan Miró (1893–1983), Willem de Kooning (1904–1997), and Jackson Pollock (1912–1956).
Room 2: The Soak-Stain Technique & The Early European Trips
On October 26, 1952, Frankenthaler produces her key work, Mountains and Sea, using a completely new process: She pours paint onto an unprimed canvas that she had placed on the floor. The fabric absorbs the heavily diluted oil paint, creating translucent and luminous areas of color that leave the structure of the canvas visible. This marks a technical breakthrough that fundamentally changes how painting can function—color becomes part of the canvas itself rather than a layer sitting on top of it. Frankenthaler moves across the entire canvas, working on it from all sides and manipulating the paint with brushes, sponges, and other tools. This method differs radically from the traditional way of painting with a brush at an easel. She deploys her whole body to engage with the entire space. With this technique, Frankenthaler breaks from artistic predecessors and establishes her own pictorial language.
Frankenthaler takes many trips to Europe during her lifetime. They are formative experiences for her artistic development. In 1948, she travels across the Atlantic for the first time and in subsequent trips encounters works of great art historical significance. She visits major museums and important exhibitions. The impressions left by the landscapes, cultural sites, and art works flow into her painting. Frankenthaler is particularly taken with the prehistoric cave paintings in Altamira. In 1953 and 1958 she visits the cultural site in Spain several times. The artist sees a connection to her own painting and compared the rough cave wall to the untreated canvas in her works.
Room 3: Homage to Painting
In 1956, Frankenthaler begins producing works that are inspired by encounters with other artworks. Her models range from Titian (ca. 1488–1576) to Marie Laurencin (1883–1956), demonstrating a remarkable stylistic and temporal breadth. She responds to specific paintings or draws inspiration from the way artists worked in the past.
In the early 1960s, new art movements such as Pop Art, which draws on imagery from advertising, consumer goods, and popular media, and Color Field painting emerge. In this period of artistic upheaval, Frankenthaler also starts to question the techniques she had been using. She begins to produce airy and partially figurative pictorial constructions.
Room 4: Biography
In the fourth room, visitors are invited to delve deeper into Frankenthaler’s life and creative evolution: a richly illustrated biography retraces key stages of her life, complemented by the twenty-minute film portrait Helen Frankenthaler: Let the Picture Lead You by Maria Anna Tappeiner (Wolf Truchsess von Wetzhausen / WESTEND Film & TV Produktion, 2025), which captures the artist’s extraordinary charisma.
Room 5: Line and Surface
Around 1970, Frankenthaler enters a particularly productive phase. She continues to develop her painting technique and experiments with bolder applications of pigment, producing large-format works that are reminiscent of landscape but consist of abstract areas of color.
In works such as Flood (1967), the focus is still on the color field. Shortly thereafter, the line reappears in her works as a finely drawn stroke, but it does not form a contour or a boundary. Rather, the line becomes an autonomous pictorial element that provides a counterpoint to the fields of color and gives structure to the canvas. This interplay of linearity and area creates a spatial effect. In works such as Moveable Blue (1973 ), the line increasingly becomes a painted element.
Room 6: Materiality and Experiment
In the early 1960s, Frankenthaler starts to experiment with acrylic paints. In some works, the wood grain of the floorboards imprints onto the canvases, and Frankenthaler integrates this effect into her visual language. While producing other works with thick layers of paint, she discovers that the color penetrates through to the back of the canvas. She then turns the works over to continue painting on the flip side. The latter came to be referred to as “floorboard paintings” and are an example of her intense exploration of materiality and pictorial space.
Her approach to paint as substance, surface, and process is part of a broader postwar rethinking of what painting can be, explored by many Western artists of the time.
Room 7: New Painterly Experiments
In the 1970s, Frankenthaler widens the scope of her painting style. Still working on the floor, she produces works with textured and multilayered surfaces, applying the paint in a variety of ways and layering it with different tools. Despite extended expanses of color, the paintings retain a spatial depth created by transparent layers of paint.
Frankenthaler’s works on paper also take on greater significance during this period. She regards them as autonomous works, approaching their production in much the same way as her paintings and imbuing them with the same expressive power.
Towards the end of the decade, she returns again to the study of 15th- to 17th-century painting. Using thin veils of color over a dark ground, she creates effects of light and shadow similar to what she had seen in the work of artists such as Titian or Rembrandt (1606–1669).
Room 8: Paraphrases in the 1980s
In the 1980s, Frankenthaler once again engages intensively with works from the history of art, responding to a variety of specific works that range from Japanese woodcuts to paintings by European artists such as Gustave Courbet (1819–1877) and Édouard Manet (1832–1883). In these encounters, she does not copy the paintings but paraphrases them by transforming them into her own abstract visual language.
These historical works serve as a starting point for what she seeks in her own creative process: “Scale and the play of space and light are largely what it’s all about.” (1996). The motifs of her pictorial models are still partially recognizable, but they dissolve into stormy landscape or atmospheric spaces. In this period Frankenthaler uses a wide range of methods to apply color. Thin layers and spatters of paint can be seen next to energetic sweeps and impasto clumps of color.
Room 9: The Last Productive Years
In the late 1980s, Frankenthaler begins a series of paintings with dynamic painted surfaces and contrasting color effects. The intense, glowing colors on a dark ground are reminiscent of stormy landscapes. In the early 1990s, too, her expressive painting continues to be inspired by an engagement with natural phenomena. The application of color, however, became more thickly layered.
In her final productive years, Frankenthaler focuses increasingly on large-scale works on paper, which she created at her studio table. Her interest in the artists of the past, such as Claude Monet (1840–1926), Rembrandt, or James McNeill Whistler (1834–1903), remain ever-present. She paints her last canvases, including Cloud Burst, in 2002, which is unique and circles back to her beginnings in the early 1950s and the soak-stain technique.
1st floor foyer: “Salome”
Helen Frankenthaler’s Salome (1981) is installed at the entrance to the Kunstmuseum Basel’s collection of U.S. American art, in the company of works by artists she knew and with whom she exchanged ideas. The collection has deep roots: As early as 1959, a donation made the Kunstmuseum the first European institution with a collection of contemporary painting from the U.S. Key works by Franz Kline (1910–1962), Barnett Newman (1905–1970 ), Mark Rothko (1903–1970), and Clyfford Still (1904–1980) form the basis of what remains a central focus of the collection to this day. With the donation of the painting Riverhead (1963) by the Helen Frankenthaler Foundation in 2024, one of the most important woman painters of U.S. postwar art is now also represented in the art museum.
