Franz Kline

Kline built large abstract paintings from sweeping black strokes laid against white grounds. He worked at night under harsh light to sharpen the contrast, and applied both oil and house paint with wide brushes, leaving a physical record of the arm's movement across the canvas. The forms read as architectural, like beams or scaffolding, though Kline insisted they carried no symbolic content and rejected the frequent comparison to Japanese calligraphy.

Kline was born in 1910 in Wilkes-Barre, Pennsylvania, and studied at Boston University from 1931 to 1935 before continuing at the Heatherley School of Fine Art in London, where he met his future wife, the dancer Elizabeth Parsons. He settled in New York in the late 1930s and worked figuratively for years. The friendship and example of Willem de Kooning was decisive: Kline began projecting small ink sketches onto his studio wall and enlarging the brushstrokes to mural scale, the exercise that produced his signature abstraction. His breakthrough came with a 1950 solo show at the Charles Egan Gallery.

Through the 1950s he became a central figure of the New York School, shown in the Museum of Modern Art's touring exhibition The New American Painting in 1958 and at the Venice Biennale. He died in New York in 1962 of rheumatic heart disease, at fifty-one, leaving a concentrated body of work that has anchored his market ever since.

Kline sits at the center of the critical account of Abstract Expressionism. The poet and curator Frank O'Hara treated him as the quintessential action painter, and Harold Rosenberg placed him alongside de Kooning and Pollock in his influential definition of Action Painting; Clement Greenberg championed the work while steering attention toward its abstract form rather than any source or symbol. The recurring critical theme is the gesture as subject: the black stroke is not a sign of something else but a record of the act of painting, which is why Kline resisted the calligraphy reading so consistently. His reputation cooled somewhat after his early death in 1962, then was reassessed upward during the market and scholarship of the late 1980s, and a later generation of Minimalists, including Donald Judd and Richard Serra, was drawn to the architectonic structure of his canvases even as they set aside the heroic gesture. Debate today centers less on his importance than on where individual late paintings rank within a small, tightly held body of work.

Kline's market is mature and supply-constrained, the profile of a deceased master rather than a living artist. His auction high is Untitled (1957), which sold for USD 40.4 million with fees at Christie's New York in November 2012, against a hammer of about USD 36 million to a telephone bidder. The result confirmed the top tier of his market and was followed by King Oliver (1958) at USD 26.5 million in 2014 and Steeplechase (1960) at USD 21.4 million in 2015, both at Christie's New York. The strongest results cluster in his late, large black-and-white canvases from roughly 1957 to 1961.

Because Kline died in 1962, the supply of his work is fixed, and the major paintings rarely come to market; when they do, results turn heavily on date, scale, and condition rather than on a smooth trend line. The black-and-white canvases of his late period are the most sought after and account for nearly all of the top auction prices. A comprehensive catalogue raisonne is in progress at the Hauser & Wirth Institute, which over time should sharpen attribution and provenance research; until it is complete, careful provenance and verification through the estate and archive matter more than usual. For a collector, the depth of museum holdings, from the Museum of Modern Art and the Metropolitan Museum to the Whitney and Tate, is the clearest signal of long-term durability.
