Konrad Peter Cornelius Klapheck born on 10 February in Düsseldorf. His father, Richard Klapheck (b. 1883), was professor of art history at the Art Academy in Düsseldorf until dismissed by the Nazis in 1934. His mother, Anna Klapheck, née Strümpell (1899), will teach at the same academy after 1945.

Father dies.

Begins elementary school.

First bomb attacks on Düsseldorf; his mother takes Konrad to Leipzig.

4 December, bomb attack on Leipzig. His grandparents’ home burns down; Konrad finds the red sky from the burning city a marvellous spectacle. Stays until 1945 in the Ore Mountains, Saxony.

Witnesses the May invasion by the Red Army from a hiding place in the woods. Later there are friendly encounters with Soviet soldiers. Takes private Russian language course. Returns to Düsseldorf at the end of the year.

Starts Humboldt High School. The art teacher, Kurt Prechtl, encourages him outside school hours. He gives him an assignment to draw a screw, greatly enlarged. First encounter with works by Matisse, Braque and Picasso at the exhibition Masterpieces of French Painting in Düsseldorf. Being inclined towards classical art and Albrecht Dürer, Konrad reacts at first with confusion, later with enthusiasm.
Reads extensively: at first fairy tales from world literature, stories from classical antiquity, German sagas and folk tales, then the Bible, which he begins to illustrate. In the literature of the nineteenth century it is mostly descriptions that fascinate him: that of a hotel room by Gogol, a harpoon by Melville, a second-hand dealer’s shop by Gottfried Keller. Discovery of modern literature: Kafka in 1949 (in the original editions of Schocken Verlag, Berlin), Joyce in 1951, Proust in 1954, Lautréamont in 1955.

First encounter with authentic jazz at a Duke Ellington concert in Düsseldorf. Klapheck begins to collect records: Count Basie, Lester Young, Coleman Hawkins, Charlie Christian, Charlie Parker, Thelonious Monk.

Three weeks in London, staying with an English friend. Visits the Tate Gallery (now Tate Britain), the National Gallery and the British Museum and attends a performance of Cole Porter’s Kiss Me, Kate.
Remains a member until 1954 of several sport clubs (boxing, athletics).

Travels to Italy with his mother (Verona, Venice, Florence, Ravenna, Rome). Takes lessons at a dancing school, where he meets his future wife, Lilo Lang.

Graduates from high school (Abitur with Latin and Greek). Trip to Paris. Calls unannounced on Max Ernst, who gives him a signed copy of Sept Microbes. Begins studies at the Art Academy in Düsseldorf, where for a year he attends Bruno Goller’s life-drawing class. Klapheck completes two series of drawings, one in the style of Matisse, which his teacher likes, one for himself in imitation of Ingres.

First painting of a typewriter. Goller encourages him to paint objects and discourages his flirtation with abstraction and tachisme.

Stays for six months in Paris, first with Lilo Lang in the rue des Saints-Pères, later alone in Versailles. An attempt to enter the École des Beaux-Arts is turned down. Begins a friendship with the painter Christian d’Orgeix (b. 1927), who shows him original works by Marcel Duchamp (1887–1968) (Rotoreliefs, La Boîte verte) and lends him the novels of Raymond Roussel (1887–1933). Meets Édouard Jaguer (1924–2006), poet, organizer of exhibitions and publisher of the magazine Phases, with whom he will later collaborate.

Publishes a booklet of small-scale drawings using klecksography (inkblots) and decalcomania, influenced by Max Ernst (Eremitenpresse, Stierstadt in the Taunus). Meets Yves Klein (1928–1962) at Klein’s first exhibition in Germany at Galerie Schmela, Düsseldorf. Later translates some texts for him into German.

The New York art dealer George Staempfli visits Klapheck in his studio and buys six paintings for $1000. They are shown 1960 in the New York exhibition Paris Obsessions, along with works by Yves Klein, Soto and Fontana.
First solo exhibition at the Galerie Schmela, Düsseldorf. The only two paintings sold are bought by Willy and Fänn Schniewind for their collection. Reviews are mostly negative.

Marries Lilo Lang and sets up house. Visits the painter Richard Oelze (1900–1980) in Worpswede and buys a drawing, the basis for a small Oelze collection. Klapheck receives a North Rhine-Westphalia art award (Förderpreis des Landes Nordrhein-Westfalen). Later he will refuse all prizes and other honors. In his first solo exhibition in a foreign country twenty-four pictures are shown in Milan at the Galleria Schwarz. The painter Enrico Baj (1924–2003) is one of the first buyers. At the opening Klapheck meets the surrealist poet E.L.T. Mesens (1903–1971) and the painter Sergio Dangelo (b. 1932).

The art critic José Pierre introduces Klapheck to the circle of Paris Surrealists, with whom he forms contacts. He visits André Breton (1896–1966) who encourages him to participate in the evening meetings at the Café La Promenade de Vénus.

The New York art dealer Leo Castelli visits Klapheck in his studio. Klapheck learns of a new art movement in America, later called Pop Art, that has parallels with his work. Castelli buys four pictures. The art dealer Rudolf Zwirner represents Klapheck in Germany and gives him several solo exhibitions.
First museum purchase by Niedersächsisches Landesmuseum Hannover . Klapheck meets the surrealist painter René Magritte (1898–1967) at a Magritte exhibition in Knokke-le-Zoute. He visits Brussels where Magritte criticizes the textured background of several pictures Klapheck brings with him: ‘The subjects are authentic. Why these picturesque additions?’ Magritte gives him a drawing.

Birth of his daughter Elisa.

Meets the artists George Segal, Tom Wesselmann and James Rosenquist. Attends the weekly fight nights at Madison Square Garden.

In US and Europe a new movement arises called Hyperrealism or Photorealism, which underlines Klapheck’s modernity, but also seems – through the technical virtuosity of some of its members – to eclipse Klapheck and his world of consciously simplified images. Participates in several exhibitions of this new movement: Ekstrem Realism at the Louisiana Museum (1973), in Humlebaek, Denmark, and Hyperréalistes américains – Réalistes européens (1974) in CNAC, Paris.

Werner Schmalenbach purchases the painting Der Krieg [War] for the Kunstsammlung Nordrhein-Westfalen.

Retrospective in Museum Boijmans-van Beuningen, Rotterdam, and later in Brussels and Düsseldorf (to 1975).

Until 1980 intensive work in etching at the Atelier Hartmut Frielinghaus in Hamburg. Klapheck engraves twenty-six plates, copies of which are partly printed in different states, which Rudolf Zwirner shows in his Cologne gallery in 1977. For the first time preliminary drawings on a scale of 1:1 are exhibited, as Klapheck regularly produced them since 1973 for his paintings. Because of the movements New Fauves, New Expressionism and Graffiti Art, audience interest is distracted into other directions and Klapheck finds himself in the position of being no longer contemporary and not yet classical.
Accepts a professorship at the State Art Academy in Düsseldorf to teach painting.

Exhibition at the Galerie Aimé Maeght, Paris, with twenty-five works.

Meets the costume designer Wanda Richter-Forgách, who inspires several important pictures: Confession, The Charming Scatterbrain, Man’s World II and others.

Meets Josef Tal (1910–2008), a composer living in Jerusalem, and studies his music. Werner Hofman purchases the 1989 painting Confession for the Kunsthalle Hamburg on the occasion of his retirement.

To coincide with the exhibition the Verlag Schirmer/Mosel produces a book with comments by Klapheck and an epilogue by Christoph Danelzik-Brüggemann.
